robertoj Posted August 25 Share Posted August 25 I am experimenting with a cheap ILI9341 screen and mi OrangePi Zero LTS https://www.aliexpress.us/item/2251832431328471.html I found these recent instructions to be able to display graphics here: https://ryjelsum.me/homelab/xpt2046-ili9341-opi-zero/ with a reference to a previous experience (without mentioning success) https://hackaday.io/project/190371-g-edm/log/217902-first-success-with-armbian-nanopi-and-ili9341-touch and independently, I found these instructions and experiences here: https://docs.armbian.com/User-Guide_Allwinner_overlays/ https://forum.armbian.com/topic/27457-connecting-banana-pi-m2-zero-with-ili9341-display-over-spi-on-latest-armbian-image/ <-just found it and it has some success with BananaPi M2 Zero https://tech-de.netlify.app/articles/de547180/index.html https://4pda.to/forum/index.php?showtopic=782242&st=5060#entry112401076 I connected with wires as shown in instructions: https://forum.armbian.com/topic/28674-text-version-of-orange-pi-zero-pinout/ And the LCD's LED input pin to 3.3V I activated the spi-add-cs1 overlay in arbian-config I copied the dts for opiZ into ~/ili9341/ili9341-touch-double-spi-cs.dts Then, I executed: cd ili9341 armbian-add-overlay ili9341-touch-double-spi-cs.dts Then, I rebooted, and my LCD just looks gray.

Should I downgrade to Linux 6.1.53? 1 Quote Link to comment Share on other sites More sharing options...

robertoj Posted October 8 Author Share Posted October 8 When the chip select is not specified, as above, the gpio pin is available for other uses I read somewhere that the ili9341 does not need the MISO wire because no information is read from the LCD ever... is this true? Some people are getting away with it https://forums.raspberrypi.com/viewtopic.php?t=370089 Also, if a wire is loose momentarily, the LCD locks up or turns "white-washed"... is there a way to reset the LCD and its KO module? 0 Quote Link to comment Share on other sites More sharing options...

robertoj Posted October 17 Author Share Posted October 17 I either have something miswired, or the hardware doesn't like the spi-gpio, but I have constant problems switching into X11. I want to try the most commonly method: one SPI bus, 2 chip selects, as shown in this example: https://github.com/dev-null2019/orangepizero2w35tft/blob/main/joyit35a-overlay.dts But modifying it from opiz2w to opiz3. The DTS by dev-null2019 has this connection wiring list: cs0=ph5 pin 24 (user defined,lcd) cs1=ph9 pin 26 (_____,touch) res=pi6 dc=ph4 irq=ph2 mosi=ph7 (native) miso=ph8 (native) clk=ph6 (native) 3v3=native 0v=native It looks weird to me that in line 9 of the DTS, only the CS0 is specified, but not CS1... is that normal? Is everyone feeeding the LCD with 3.3V or 5V? (I was using 3.3V because that works great in my orange pi zero) Has anyone had success with the backlight gpio parameter? Is it ok to use 5V instead of 3.3v? This would be the modified wiring list, for opiz3: cs0=ph5 pin 24 (user defined,lcd, next to 5V) cs1=ph9 pin 26 (native,touch) res=pc14 dc=pc7 irq=pc10 mosi=ph7 (native, both touch and lcd) miso=ph8 (native, touch only) clk=ph6 (native, both touch and lcd) led=3v3 (native) 5v=pin 5 (native, use next pin ph5 for cs0) 0v=native 11 wires, 2 with Y splitter in physical pin order: 3=cs0 4=5v 17=3v3 18=res < 3v3 for LED 19=mosi 20=gnd < mosi with Y 21=miso 22=dc 23=clk 24=cs1 < clk with Y 26=irq Spoiler in physical pin order: 3=cs0 4=5v 17=3v3 18=res < 3v3 for LED 19=mosi 20=gnd < gnd with Y 21=miso 22=dc 23=clk 24=cs1 < clk with Y 26=irq LCD pin order (14 pins): *5 pin connector irq < 1-brown tmiso < 2-red tmosi < 6-blue (Y with mosi) tcs < 3-orange tclk < 5-blue (Y with clk) *4 pin connector miso (no connection) led (3v3)< 4-yellow clk < 5-green (Y with tclk) mosi < 6-blue (Y with tmosi) *5 pin connector dc < 7-purple reset < 8-gray cs < 9-white gnd < 10-black vcc (5v) < 11-brown wire color code 1=brown 2=red 3=orange 4=yellow 5=green 6=blue 7=purple 8=gray 9=white 10=black 11=brown 0 Quote Link to comment Share on other sites More sharing options...
Ivano Posted October 18 Share Posted October 18 Hello there. First time posting on this forum so I apologize in advance if there is any issue with my post. I have been learning and using Armbian for some time on an Orange Pi Zero 2W intended for Klipper with an ili9341 as a screen for KlipperScreen. In order to have the display and touch working with the CS0 and CS1 pins, I used the dts provided below. I am not very knowledgeable about the structure required in dts files, so I tried to keep all the values the same from the examples that I found online on this forum and Github and only modified what I required or what seemed to work for my case. Pins were assigned in the following way: CS0 = Connected to CS from display CS1 = Connected to T_CS from touch IRQ = PI5 Reset = PI6 DC = PH4 LED = PI14 (PWM) These were connected to the same pins in display and touch MOSI = PH7 | Connected to SDI (MOSI) and T_DIN MISO = PH8 | Connected to SDO (MISO) and T_DO SCL = PH6 | Connected to SCK and T_CLK Backlight is controlled by pin PI14 which is assigned to pwm4 in fragment@0 since pwm4 is assigned to PH1 by default on the Orange Pi Zero 2W and that pin was a bit far from the rest. At first I was using gpio-backlight on PI14 to control the backlight, so I left those values commented in the dts just for future reference. For VCC I used the 3.3V pin from the Orange Pi Zero 2W. In regards to CS, I once tried to define both, CS0 and CS1, in cs-gpios at the same time but the dts never loaded when I did this. However touch appears to work fine on CS1 even when only CS0 is defined in cs-gpios. No additional overlays from armbian-config were required for this. Something I noticed and I am not sure if this has to do with my configuration, the drivers, my wiring, or the screen itself, but when the screen was turned off by dpms on an X11 session, touch would stop working on some occasions and touch activity was no longer displayed with evtest which always forced me to reboot the device in order to make it work again. Reloading the ads7846 driver did not help since I always receive an error saying "ads7846 spi1.0: failed to request pendown GPIO" when trying to load the driver with modprobe after unloading it. Due to that issue, I changed the backlight to a PWM pin and instead of completely turning it off, I now set it at the lowest brightness level. I have not yet encountered the same problem again after making this change, so the source of the issue is still a mystery for me. Anyways, I hope any of this information is helpful for the Orange Pi Zero 3.

Ivano, check whether PI5 (your desired IRQ) is not already claimed by the kernel, with the last command I show up there (pinmux-pins) Maybe you can try other GPIO. Then, if it doesn't work, try changing the level and edge polarity parameter (I talk about it in this thread or the other recent ili9341 thread). In your case: use PI5 <8 5 _>, interrupts = <2 10 2>; /* PC10 - IRQ */ < try changing 2 (active high) into 8 (active low) I HAVE NEVER CHANGED THIS pendown-gpio = <&pio 2 10 1>; /* PC10 */ <try changing 1 (edge rising) into 0 (edge falling) Opiz2w reference: More useful discussion here: https://forum.armbian.com/topic/27457-connecting-banana-pi-m2-zero-with-ili9341-display-over-spi-on-latest-armbian-image/page/2/#comments 0 Quote Link to comment Share on other sites More sharing options...

Ivano Posted October 20 Share Posted October 20 I am glad you are making further progress and thankful for sharing your findings. I tried your suggestions and it appears that the pin for IRQ (PI5) is listed as unclaimed when the dts is not loaded, so it appears to be available for use. I previously tried using different pins for IRQ thinking that maybe the one that I was using did not properly support interrupts and that it was causing the random missing touch problem, but the result was the same and touch was randomly lost after the backlight was powered off. This could happen after a few minutes, but sometimes it did not happen even after a full day. I noticed that the problem did not happen when the backlight was not powered off, which is why I decided to dim the backlight to its lowest value instead of powering it off. When I was first trying to make touch work, I had 0 (edge falling) on pendown-gpio which resulted in touch not being registered. Most of the dts I found online had this value set to 0 (edge falling), so it took me a while to try changing the value to 1 (edge rising) to make it work. Anyways, I tried your suggestion about using different values in "interrupts" and touch was still being registered with the value 8, so I will make further tests with this configuration to see if it makes a different for my case. I also tried the dts provided in your last reply with the required modifications for my board (I only changed the pins to match the ones for my board) and with the backlight now connected to 3.3V, but the dts was not loaded and I was presented with a white screen. Logs displayed issues claiming PH9 (CS1) and said that it was already requested. Once I removed CS1 from cs-gpios, the dts was loaded and the display and touch were working properly. The interesting thing is that while logs were complaining that PH9 (CS1) was already requested when both CS were defined in cs-gpios, pinmux-pins was still listing PH9 as unclaimed. But after removing PH9 from cs-gpios, pinmux-pins then listed the pin as claimed and everything seemed to work. I am not sure why this is happening but it appears that your board requires you to explicitly define both CS while mine only wants one in the dts. Below I will provide some details from loading the dts with both CS and with only CS0 defined. This is with the dts from your last reply with both CS defined which is not working for me. | cs-gpios = <&pio 7 5 0>,<&pio 7 9 0>; // PH5=CS0, PH9=CS1 Spoiler cat /sys/kernel/debug/gpio gpiochip0:

robertoj Posted October 20 Author Share Posted October 20 That’s very interesting… why my opiz3 needs both CS defined and the opiz2w only wants one CS defined. but please make further tests and confirm this works with lightdm Sudo apt install lightdm xorg-input-evdev sudo cp /usr/share/X11/xorg.conf.d/45-evdev.conf /etc/X11/xorg.conf.d/ (https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A)_Manual_Configuration) sudo systemctl disable lightdm sudo startx (in second ssh) sudo DISPLAY=:0.0 xinput-calibrator do the calibration plug usb keyboard and mouse Sudo systemctl start lightdm check that the cursor moves with touch or pen right click and 0 Quote Link to comment Share on other sites More sharing options...
Ivano Posted October 22 Share Posted October 22 Hello again. I followed the steps and performed the calibration and LightDM seems to work fine with the display and touch. I only did a short test, but the cursor was moving together with the pen while in the login screen. I currently have KDE Plasma installed and this desktop environment appears to be too big for this screen resolution, however the cursor was still moving with the pen while being in the desktop and I was also able to drag a window and move it around. The only small issue I noticed is that even after performing the calibration, the cursor was getting a small offset from the touch point the farther I was getting from the center of the screen and this made it difficult to reach the border section and also the corners. I experienced problems closing a maximized window due to this. This was somehow resolved after setting a better value range for the min and max values for x and y in the dts. I got the required values by using evtest, then touching each corner, and comparing the minimum and maximum values registered in ABS_X and ABS_Y. My numbers might require some tuning but they are working fine for now and I am able to reach all four corners without the cursor offset issue. Please note that the values reported in ABS_X and ABS_Y are in a decimal format instead of hexadecimal. Spoiler Minimum values: Event: time 1729638604.477383, type 3 (EV_ABS), code 0 (ABS_X), value 174 Event: time 1729638604.477383, type 3 (EV_ABS), code 1 (ABS_Y), value 260 Maximum values: Event: time 1729637910.370625, type 3 (EV_ABS), code 0 (ABS_X), value 3808 Event: time 1729637910.370625, type 3 (EV_ABS), code 1 (ABS_Y), value 3767 ti,x-min = /bits/ 16 <200>; ti,x-max = /bits/ 16 <3800>; ti,y-min = /bits/ 16 <200>; ti,y-max = /bits/ 16 <3800>; If you experience the same offset problem, please feel free to try this to see if it helps you resolve it. I hope this information is helpful. 0 Quote Link to comment Share on other sites More sharing options...
robertoj Posted October 22 Author Share Posted October 22 I HAD the same issues with calibration. The 99-calibration.conf needs to be created, with the output of xinput-calibrator. It is not automatically done. You also need the evdev.conf file copied from usr/share/... to /etc/X11. When I wasn't doing this, I did the calibration many times and it wasn't effective. Read https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A)_Manual_Configuration very carefully and follow all steps regarding calibration. 0 Quote Link to comment Share on other sites More sharing options...
Ivano Posted October 22 Share Posted October 22 Thank you for your quick response. I created the 99-calibration.conf file in /etc/X11/xorg.conf.d/ with the values provided by xinput_calibrator, however it appears that I somehow forgot to copy 10-evdev.conf to /etc/X11/xorg.conf.d/ while testing. After copying 10-evdev.conf to the intended directory and running xinput_calibrator, I now get a different set of values and after putting them in 99-calibration.conf, the calibration is now being properly applied. 0 Quote Link to comment Share on other sites More sharing options...
robertoj Posted Saturday at 03:50 AM Author Share Posted Saturday at 03:50 AM Hello Ivano Can you control the backlight? If so, can you share your whole DTS? (opiz2w) 0 Quote Link to comment Share on other sites More sharing options...
Ivano Posted Tuesday at 08:42 PM Share Posted Tuesday at 08:42 PM (edited) Hello Robertoj. Yes, I can control the backlight via /sys/class/backlight/ when it is configured with gpio-backlight or pwm-backlight. You may find below the default dts for the Orange Pi Zero 2W on kernel 6.6.44.

robertoj Posted yesterday at 04:54 PM Author Share Posted yesterday at 04:54 PM Thank you, but I was referring to the 1 DTS that enables the ili9341, ads7846 and pwm-backlight, just in case you made a last change that you didn't mention. 0 Quote Link to comment Share on other sites More sharing options...
Ivano Posted yesterday at 08:02 PM Share Posted yesterday at 08:02 PM This is the latest dts that I used with pwm-backlight. The only changes I made from the previous dts were moving ili9341 to CS1 and ads7846 to CS0, changing the default calibration values for ads7846, and adjusting the brightness values in pwm-backlight. Spoiler /dts-v1/; /plugin/; / { compatible = "allwinner,sun50i-h616"; fragment@0 { target = <&pwm4_ph_pin>; __overlay__ { pins = "PI14"; // Assign PI14 to pwm4 function = "pwm4"; }; }; fragment@1 { target-path = "/"; __overlay__ { backlight: backlight { compatible = "pwm-backlight"; pwms = <&pwm 4 1000000 0>; // PI14 - pwm4 brightness-levels = <0 8 16 32 64 96 128 160 208 255>; default-brightness-level = <9>; post-pwm-on-delay-ms = <10>; pwm-off-delay-ms = <10>; status = "okay"; }; }; }; fragment@2 { target = <&spi1>; __overlay__ { /* needed to avoid dtc warning */ #address-cells = <1>; #size-cells = <0>; status = "okay"; cs-gpios = <&pio 7 5 0>; // PH5 - CS0, PH9 - CS1 ili9341: ili9341@0 { compatible = "adafruit,yx240qv29", "ilitek,ili9341"; reg = <1>; // CS1 pinctrl-names = "default"; spi-max-frequency = <32000000>; rotation= <90>; fps = <30>; buswidth = <8>; height = <240>; width = <320>; reset-gpios = <&pio 8 6 0>; // PI6 dc-gpios = <&pio 7 4 0>; // PH4 backlight = <&backlight>; //debug = <3>; }; xpt2046: xpt2046@1 { compatible = "ti,ads7846"; reg = <0>; // CS0 pinctrl-names = "default"; spi-max-frequency = <1000000>; interrupts = <8 5 2>; // PI5 - IRQ interrupt-parent = <&pio>; pendown-gpio = <&pio 8 5 1>; // PI5 ti,pressure-min = /bits/ 16 <0>; ti,pressure-max = /bits/ 16 <255>; ti,x-plate-ohms = /bits/ 16 <40>; ti,y-plate-ohms = /bits/ 16 <40>; ti,x-min = /bits/ 16 <170>; ti,x-max = /bits/ 16 <3800>; ti,y-min = /bits/ 16 <200>; ti,y-max = /bits/ 16 <3800>; ti,debounce-rep = /bits/ 16 <1>; ti,debounce-tol = /bits/ 16 <2>; ti,debounce-max = /bits/ 16 <100>; ti,settle-delay-usec = /bits/ 16 <20>; ti,penirq-recheck-delay-usecs = /bits/ 16 <20>; ti,keep-vref-on = <1>; ti,swap-xy = <0>; wakeup-source; }; }; }; }; For gpio-backlight I used the following fragment which replaces fragment@0 and fragment@1 from above. Spoiler fragment@0 { target-path = "/"; __overlay__ { backlight: backlight { compatible = "gpio-backlight"; pinctrl-names = "default"; gpios = <&pio 8 14 0>; // PI14 default-on; status = "okay"; }; }; }; Make also sure that backlight = <&backlight>; is included inside the ili9341 section in order to have the backlight working or it will most likely not power on after the device boots. 0 Quote Link to comment Share on other sites More sharing options...
