October 8, 20242 yr Hello I have this display http://www.lcdwiki.com/4inch_HDMI_Display-C and touchscreen doesn't work. I write dts file but apparently he is not a privelege and the touchscreen did not work. Can point out my mistakes when writing dts? rockchip-ads7846.dts Edited October 8, 20242 yr by maximilian fletkar
October 8, 20242 yr Document everything in your DTS, including how you calculate the GPIO numbers and the describe the physical wiring Make sure you use armbian-add-overlay correctly, and armbianEnv.txt doesn't include previous dtbo experiments. Send a schematic of your touch chip pins and your ARM board This is a reference on how it is done with an Allwinner H3 and spi-gpio. https://forum.armbian.com/topic/27457-connecting-banana-pi-m2-zero-with-ili9341-display-over-spi-on-latest-armbian-image/?do=findComment&comment=202734 Try changing the active-high/active low/edge up/edge down parameters
