Sl8rBug Posted January 14, 2021 Posted January 14, 2021 I am in the process of setting-up a RockPi-E as a Nextcloud server. I am running the latest Armbian Focal "current" mainline kernal and have migrated the rootfs to a SSD using this link as a guide:- https://wiki.daniel-keil.de/projekte/banana-pro/install-armbian-to-a-sata-drive I have successfully installed nginx, MariaDB, PHP and Nextcloud using various guides and Nextcloud is operating very well. I would like to have some "blinky lights", a shutdown button and connect an I2C LCD display. I2C1 is working on GPIO header pins 27,28 but I have not seen any mention of I2C1 in any documentation and only discovered when I was studying the 40 Pin Header (GPIO Pin-Out) table at https://wiki.radxa.com/RockpiE/hardware/gpio (I have a V1.2 revision board). I2C7 and I2C8 are shown in armbian-config ->System settings ->Hardware and the file /boot/dtb/rockchip/overlay/README.rockchip-overlays show which GPIO to use as SDA & SCL but those ports do not appear in the 40 pin header table. What I would like to know:- Is there a library (prefer python) that I can use to access the GPIOs in userspace? Can I2C7 & I2C8 be used on the RockPi-E? If so, which pins can I use? How can I use PWM2? (Pin 33 on the 40 pin header) I am reasonably fluent in Raspberry Pi and have a couple of OrangePi Zeros but I'm finding the RockPi-E is a bit more difficult to interface to. Any help welcome. Regards, John PS. How do I turn off the Green Power LED? It's BRIGHT!
ChrisO Posted February 14, 2021 Posted February 14, 2021 You cannot turn off the green LED. https://wiki.radxa.com/RockpiE/hardware/rockpiE states: "Green Power LED is always on and couldn't be controlled by software." Regards, Chris
