Orange Pi Zero 3 ili9486 TFT LCD

WDR_s · October 31

I have this screen here ili9486 : https://pt.aliexpress.com/item/32805704334.html?src=google&pdp_npi=4%40dis!BRL!43.31!38.51!!!!!%40!12000019014148570!ppc!!!&src=google&albch=shopping&acnt=768-202-3196&isdl=y&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&aff_short_key=UneMJZVf&gclsrc=aw.ds&&albagn=888888&&ds_e_adid=&ds_e_matchtype=&ds_e_device=c&ds_e_network=x&ds_e_product_group_id=&ds_e_product_id=pt32805704334&ds_e_product_merchant_id=107713925&ds_e_product_country=BR&ds_e_product_language=pt&ds_e_product_channel=online&ds_e_product_store_id=&ds_url_v=2&albcp=21106536414&albag=&isSmbAutoCall=false&needSmbHouyi=false&gad_source=1&gclid=EAIaIQobChMI14GV5um3iQMVK2BIAB0KwQPmEAYYASABEgJc4fD_BwE

I would like to know if i can connect to my orange pi zero 3

I have already tried to connect but without success, as I am new to this I would like you to help me if possible.

Thanks!

Sorry for my English I'm on google.

Starting with the DTS that worked for me in the orange pi zero 3, with ili9341:

https://forum.armbian.com/topic/44191-orangepi-zero-lts-ili9341-tft-lcd-and-later-orangepi-zero-3/?do=findComment&comment=204672

My DTS is for a customized set of pins that works for me, and it is different than/from the waveshare set of pins.

You need to change:

* file name change to: ili9486-ads7846-spi1.dts

* gpio pin selections everywhere in the DTS

* "adafruit,yx240qv29" should be "ilitek,ili9486"

* change "rotation" to "rotate"

* change "reset-gpios = <&pio N N 0>;" to "reset-gpios = <&pio N N 1>;

Then sudo armbian-add-overlay ili9486-ads7846-spi1.dts

Reboot

(does anyone know the correct DRM driver for ili9486?)

I used your DTS and modified the driver and some other things and it looked like this:

};

/* OPTIONS */
ti,x-min = /bits/ 16 <0>;
ti,y-min = /bits/ 16 <0>;
ti,x-max = /bits/ 16 <0xFFF>;
ti,y-max = /bits/ 16 <0xFFF>;
ti,pressure-min = /bits/ 16 <0>;
ti,pressure-max = /bits/ 16 <0xFFF>;
ti,x-plate-ohms = /bits/ 16 <400>;
ti,swap-xy = <1>;
};
};
};

the screen didn't turn on and I get this:

I see that you didnt change any gpios. You must change them... what are the pins in the orange pi zero 3 that will control the lcd? (you must have the LCD schematic)

If you try my original DTS, without having a screen like mine, do you get these 2 files?

/dev/fb0

/dev/input/event0

According to this https://mjmwired.net/kernel/Documentation/devicetree/bindings/display/ilitek,ili9486.yaml

You must use the line:

compatible = "waveshare,rpi-lcd-35", "ilitek,ili9486";

do i have to add anything to /boot/armbianEnv.txt ? i'm in doubt!

robertoj · November 7

Regarding these lines:

cs-gpios = <&pio 2 5 0>,<&pio 7 9 0>; /*PH5=CS0 for lcd, PH9=CS1 for touch*/

reset-gpios = <&pio 0 8 1>; /* PC15 */
dc-gpios = <&pio 0 5 0>; /* PC5*/

interrupts = <2 7 2>; /* high-to-low edge triggered */
pendown-gpio = <&pio 2 7 0>;

Make sure that you make the comments match with the actual DTS code, for example PH5=<&pio 7 5 0>, because H=7

Also according to the gpio formula, C=2.

Also insert some initial comment lines at the top, summarizing the pinout you discovered for the orange pi zero 3, to show your intermediate work

You are very close. All those spi1.0, spi1.1 dmesg messages indicate that there's no conflict internally in the CPU, but probably the one or a few IOs are connected to the incorrect pin(s).

Another thing to try is change "reset-gpios = <&pio 0 8 1>" to "reset-gpios = <&pio 0 8 0>" because sometimes different kernel modules handle the polarity in the opposite way than it is expected.

Also try changing "compatible = "ilitek,ili9486";" to "compatible = "waveshare,rpi-lcd-35";" and look at the example in https://mjmwired.net/kernel/Documentation/devicetree/bindings/display/ilitek,ili9486.yaml to find the little differences in parameters.

Keep googling this forum for ili9486, maybe someone did it already

robertoj · November 11

How is it going with the ili9486 LCD?

the armbianEnv.txt only needs the user-overlay line with the dts you are using (without the dts extension)… but seeing your progress, I am sure the armbianEnv.txt is perfect as it is now

your problem might be the gpio numbers (1st and 2nd parameter in <&pio xxx xxx xxx>) and the polarity setting (3rd parameter)

DO NOT ADD ANYTHING ELSE SPI RELATED

And when I change the driver compatibility from “compatible = ‘ilitek,ili9486’;” to “compatible = ‘waveshare,rpi-lcd-35’;”, it shows this:

Every time I change the pins, the driver doesn't load correctly, it always shows me the same driver message.

Spoiler

SPI driver fb_ili9486 has no spi_device_id for ilitek,ili9486

this error is the wrong pins, but I haven't found a way to solve it yet.
Do you have any suggestions?

See all the things I have tried to make it work with ili9341... consider using dupont wires so that you can use my dts, making the pins match electrically, and changing the driver line to "compatible = "waveshare,rpi-lcd-35";

Also get an ili9341 so that you witness that it can work.

I used your dts, I just changed the drivers:

i knew it wouldn't work, but it starts the driver on your dts.
