  1. I am releasing this patch in the hope of you may find it useful. I have also included a sample dts file. It seems to work in 48mhz quite well with very few SPI errors. (Note that the pieces of the driver has been around for some time but I have never seen it put together without further work. Hopefully this patch would make it readily usable. I have tested it on 5.5.18 and quite happy with it.) 0001-fbtft-fb_ili9488.patch 1_ili9488.dts Sample file is for nanopi neo. Driver also works with 4 inch LCD, MSP4020, MSP4021
  2. Hello, I'm new here and do not quite understand the sub-forums here but hopefully this is the right one. I got an Orange pi ONE running 4.19 RT kernel with Armbian buster. I was testing out the GPIO capabilities of the H3 SoC without any libraries and got only 1.67 Mhz at best(which is ironically the same as WiringPIOP) with some task interrupt issues. #define INP_GPIO(g) *(unsigned int *)(gpio+0x04) &= ~(7 << (((g) % 10) * 3)) //I did not thoroughly check if the mapping is okay #define OUT_GPIO(g){\ *(unsigned int *)(gpio+0x04) &=
  3. A very hackish port exists of this Raspberry PI RGB LED Matrix Library which works for Allwinner H3 devices. This works by bit-banging 14 GPIO pins simultaneously to achieve about a 10Mhz throughput / 100fps refresh rate. Refer to here: https://github.com/mrfaptastic/opi-allwinner-h3-rgb-led-matrix I managed to easily get up and running using an Orange PI. Refer to the README of the github repository.
  4. Hello, I don't know where to start, but I am looking to use Velleman VM140 USB IO-board with Armbian Linux. I tried first on NanoPi R1 that I have succesfully installed Armbian Linux. Linux I have installed is Armbian Buster for NanoPi R1. root@nanopi-r1:/etc# uname -r 5.7.15-sunxi I read somewhere there is kernel support for K8061 (the usb chip on the board if I understood correctly, looks to be a pic with USB). dmesg after attaching USB cable to R1: [960949.202099] usb 6-1: new full-speed USB device number 2 using ohci-platform [960949.435136
  5. I know the RPi is pretty limited on the GPIO pins. Now my question is how it looks on Le Potato, i.E. is it possible to power a fan directly from the GPIO pins? Powering it from the 3.3 V line seems to work just fine but I fear damaging hardware by trying to connect it to a GPIO instead.
  6. Hi, all! Is it possible to make micro usb otg connection through gpio pins on the orange pi zero? I'm asking because when OPi is located in the box, I need to use external USB type B socket to micro usb cable. So it will be really cool, if I will have opportunity to connect usb otg socket through gpios. Regards.
  7. It's simple guide, presenting how to setup LCD (ili9431) with integrated touchscreen (tsc2046) on mainline kernel (4.11). It may be not fully "armbian way", since I'm pretty new in armbian In case that somebody is interested, I recently bought couple those displays from here Few basic informations: 1. OrangePiZero has two SPI buses. First one is usually occupied by build in memory. So we can only use bus1 2. tsc2046 chip is fully compatible with ads7846, and we have drivers for it since years now 3. Maximum clock frequency for ads7846 is 3.25Mhz, b
  8. Hello, I'm trying to use Armbian with a Nanopi NEO Core (Allwinner H3) mounted on its Mini Shield. I was able to use the CAN controller MCP2518FD through SPI1 and CS1. Now I need to use, always on the same SPI1, the demo board TPM SLB 9670 TPM2.0 that I have already verified on a Raspberry Pi. I found the tpm_tis_spi Kernel module by compiling Armbian Bionic 5.4.37, but I was unable to locate the DTB overlay needed to set-up the following pins: SPI1 MOSI SPI1 MISO SPI1 CLK SPI1 CS IRQ (from SLB9670's demo board to Nanopi NEO Core) RESET (f
  9. Hi there. Trying to get SPIDEV working on my good old cubietruck aka cubieboard3 with an allwinner A20. Found some posts here and there dealing with A20 boards. But nothing of that did anything for me so far. Enabled it in armbian-config hardware settings and rebooted. No /dev/spi* at all. No mentioning of "spi" in dmesg. Step 1 gave a line "overlays=spi-spidev" in /boot/armbianEnv.txt. Read somewhere else that there should be another line "param_spidev_spi_bus=0", but that was not created by armbian-config. Added that ...bus=0 line myself and rebooted. Still no s
  10. Hello Opi Community, I have an Orange Pi PC with the below HW Specs: Snippet of lshw output: description: ARMv7 Processor rev 5 (v7l) product: Xunlong Orange Pi PC width: 32 bits capabilities: smp 4 CPU Issue: Chromium locks up frequently while browsing the internet. Yes I'm running the ARMBIAN OS (Armbian Buster) Chromium Version 76.0.3809.100 (Developer Build) built on Debian 10.0, running on Debian 10.1 (32-bit) Not sure if it is an H2 or H3 board. How do I find it? It is an AllWinner Sun8i family H3 Board
  11. Trying to figure out which NOR chip to buy for my ZeroPi is giving me a headache. FriendlyArm has very little info available on what works. The board has an empty spot to solder a NOR chip that I would like to populate. There are so many chips all with different voltages and clock frequencies. The wiki and schematic omit the connection all together so I really have no idea what would work. Can someone point me in the right direction?
  12. I am trying to use a Waveshare e-Paper (2.9") with an Orange Pi Zero LTS. To enable the SPI interface, I have added this to /boot/armbianEnv.txt: overlays=spi-add-cs1 spi-spidev param_spidev_spi_bus=1 param_spidev_max_freq=10000000 and installed WiringPI from Github. The e-Paper module is connected to the following GPIO pins: VCC: 3.3V GND: GND DIN: 19(phys)/11(wPi) CLK: 23(phys)/14(wPi) CS: 24(phys)/15(wPi) DC: 22(phys)/13(wPi) RST: 3(phys)/0(wPi) BUSY: 5(phys)/1(wPi) I have checked the connections by using the gpio command line tool to set all 6 ports above to low and to high,
  13. I do some tests on a new display from WaveShare : 5.5inch HDMI AMOLED, 1080x1920 https://www.waveshare.com/product/modules/oleds-lcds/oled/5.5inch-hdmi-amoled.htm On the wiki, it's wrote : To use it on RaspberryPi, you must change the config.txt file for to ajuste hdmi parameters : https://www.waveshare.com/wiki/5.5inch_HDMI_AMOLED max_framebuffer_height=1920 max_usb_current=1 config_hdmi_boost=10 hdmi_group=2 hdmi_force_hotplug=1 hdmi_mode=87 hdmi_timings=1080 1 26 4 50 1920 1 8 2 6 0 0 0 60 0 135580000 3 I d
  14. This falls somewhere between "how-to", "research", and "development", so I stuck it here. @adafruit is working to target CircuitPython to Armbian devices, something that will be a bit of a task. I've been playing with the code to get it working on my Tritium H3, finally did (some extra sudo-ing was needed), so I'll probably toss in a couple board definitions/help here and there if I can. it had hijacked a C2 thread (not completely, it was at least about using it on the C2), and I thought it best to continue discussion here. @chwe, @sgjava, and @Larry Bank all have various experi
  15. Hi All, I am trying to use a 4x4 matrix keypad on Orange pi GPIO ,I am connecting the keypad with 8 GPIO's 4 GPIOs for rows, 4 for coloumns ,the problem I am facing is when I try to test the keypad few keys are read only on repeated attempts or pressing. The following is my code. Is this because of Hardware debouncing?. I don't have much knowledge on debouncing. I suspect there is a delay happening in reading and writing GPIOs , because of user process scheduling can be delayed. I don't think accesing GPIO at faster rate is not possible from user application. Please suggest me the
  16. Some of the boards supported by Armbian have an mpcie slot. The only one that I know of that also has a sim slot is the celarfog pro. (Correct me if I missed something) I found this little add on board that supposedly adds a sim card to an mpcie modem. Think it might work on some or which of the boards? I looked at this but I get lost in figuring out how to form the udev rules. Anyone get 4g going on Armbian on any board in the US?
  17. Hi, anybody knows what size of a heatsink can I put on an Orange Pi Zero? It is in the small cube enclosure (without additional addon board). Maybe a link to eBay or Aliexpress? Thanks!
  18. Hello, the Rock64 SBC can receive an add-on board with audio ports and an additional ethernet port. I have used it a lot before, with Debian Stretch. With the armbian image it does not work. The reason is simple, this board must be activated by a script which is missing. Ayufan has added a set of scripts in /usr/local/sbin, but they are not present in this build. They can be found here : https://github.com/ayufan-rock64/linux-package/blob/master/root/usr/local/sbin/enable_dtoverlay Then run the necessary command : enable_dtoverlay eth1 ethernet@ff550000 okay and the card
  19. Hello! Recently, Armbian Debian 10 was installed on my ODROID-C2 I can't configure lircd, but it worked on Odrobian Debian 9! Please, explain how they configure LIRC to 4.19 now without /dev/lirc*? WBR, WRA-RIPE
  20. I was able to read a DHT22 on PA10 with my Orange Pi Prime using https://github.com/Jeremie-C/OrangePi.GPIO Minimal documentation provided in readme https://github.com/lanefu/DHT22-Python-library-Orange-PI
  21. Hello, I am trying to connect an enc28j60 ethernet port to spi0.0 on an orange pi pc, running armbian (debian stretch 4.19.5). I have the jumpers all connected in what I believe is the correct pattern. I compiled a device tree (overlay?) for the enc28j60 on h3, the dtbo file now exists in /boot/overlay-user/spi-enc28j60.dtbo. /dts-v1/; /plugin/; / { compatible = "allwinner,sun4i-a10", "allwinner,sun7i-a20", "allwinner,sun8i-h3", "allwinner,sun50i-a64", "allwinner,sun50i-h5"; /* This fragment is required only if the IRQ pin requires internal pull-up */ fragment@
  22. I have orange pi pc with debian. Orange Pi is connected via mobile connection (Wifi AP). Every day I lose more than 500mb data to nothing. What I must disable to normal operations without any update?
  23. I'm not sure what will and won't be a worthy overlay to put directly into Armbian itself with the current script structure, I intend to document the ones I add here, @martinayotte may as well if he's bored. :-P I will be focusing on RPi GPIO compatibles, since those are nice pre-packaged devices in general. I have Tinker, RockPi 4, Le Potato/K2/C2, Tritium H2+/3/5, Rock64, Renegade, and some others. Everything here is a placeholder at the moment. Status Tinker Le Potato Meson64 Renegade
  24. Hi Im trying to use the Pine A64 for a robotics project but I cannot find any information about how to use the pins and peripherals. Im using Armbian Stretch and I have been looking for the information for like three days. Is there any tutorial, library or something to check how to use the pins on the board? I need to use I2C, SPI and I/O pins... Im even considering switching to RPi because of the lack of documentation... Any help is appreciated Thanks!
