  1. I am testing with the last version of Armbian (Ubuntu Bionic) and it's working fine. i2c-1 is enabled by default. sudo apt install python3-wheel python3-setuptools python3-dev build-essential sudo apt install python3-smbus git clone --depth 1 https://github.com/rm-hull/luma.oled git clone --depth 1 https://github.com/rm-hull/luma.examples cd luma.oled/ sudo -H python3 setup.py install cd ~/luma.examples/examples python3 welcome.py Don't forget to add yourself in the "i2c" group and to connect your oled in the P27 (i2c1-sda) and P28(i2c1-scl) and 3.3volts. sudo usermod -aG i2c your-login
  2. Yes, I have Rock64 working with I2C and a 20x4 LCD display like this one Aliexpress and the dbrgn/RPLCD under Python 3.6.6 (Ubuntu Bionic 18.04) : git clone https://github.com/bazooka07/RPLCD.git -b test-entrypoint-1811 ( I fix a little bug for the test ) I have too an ESP8266 (Nodemcu) and a OLed 0.96" display. I'm trying for running Oled with Rock64. The following library is working but don't keep the display on when I leave my script pip3 install luma.oled My script : #!/usr/bin/env python3 from luma.core.interface.serial import i2c, spi from luma.core.render import canvas from luma.oled.device import ssd1306 serial = i2c(port=1, address=0x3C) device = ssd1306(serial) with canvas(device) as draw: draw.rectangle(device.bounding_box, outline='white', fill='black') draw.text((30, 40), 'Hello World', fill='white') Don't forget to connect on i2c-1 pin #27 (sda) and pin #28 (scl) unlike RPI3
  3. Useful doc here : http://synfare.com/599N105E/hwdocs/rock64/index.html I am trying with Ayufan distribution : https://github.com/ayufan-rock64/linux-build/releases/download/0.7.9/bionic-minimal-rock64-0.7.9-1067-arm64.img.xz I have connecting i2c on P27 (i2c1-sda) and P28(i2c1-scl) and 3.3volts and the display is found with "i2cdetect -y 1" on 0x3f. Now, I have to install lcdproc
  4. I have a Rock64 powered by Armbian version 5.60 kernel 4.4.162-rockchip64 Ubuntu Bionic How can I activate i2c0 and i2s0 ports for connecting a 16x2 characters LCD display like 1602LCD and a PCM5102 DAC ? I'm trying armbian-config and I'm reading https://docs.armbian.com/User-Guide_Allwinner_overlays/ but I'm getting no help. Thanks for advance.
  5. Hello, Each time I'm booting the Rock64, it starts on Jan, 21 of 2016 but the filesystem has a superblock on Jan,28 of 2018, so in the future. It's inconsistant and the filesystem is checking each time and I'm waiting a few seconds. How can I avoid this trouble ? Here is the screen shot of logs through the tty/usb console. I'm booting from the spi flash and a sd-card with Ubuntu 18.04.1.
  6. @t3l3m4k0, That's working I have not this trouble with my Bananapi. Thanks a lot
