No Name 1 May 23 Hi Everyone ! I'm trying to find an Official full guide "How to setup and control GPIO on orange Pi zero devices". I find some parts of informations about it on the net but I don't understand the full steps to do it, it is not enough clear for me. 1) Some people are using unofficial python libraries. But I can see that these libraries seem being a fork from Rpi devices and all GPIO interfaces are not tested. 2) I have found the DT Overlay Guide but it explains only how to setup GPIO (not how to use it in a batch, python or c file) https://docs.armbian.com/User-Guide_Allwinner_overlays/ 3) Official sunxi documentation https://linux-sunxi.org/Main_Page https://linux-sunxi.org/GPIO In this article, it speaks first about the sysfs method but it seems a deprecated method. SUMMARY : I would like a guide with some examples that explains how to setup and control GPIOs as I/O pin, i2c port, spi port and serial port. 1) a simple example to configure a pin as input : - setup the desired pin as an input - using IO level change event/interruption with a batch, python and c file. 2) other examples with the I2C, SPI and serial port interface. 3) an history overview with all differents ways to do it with their life state (deprecated, official/non-official, etc.) 0 Share this post Link to post Share on other sites
