Eric Keller Posted October 2, 2022 Share Posted October 2, 2022 Hello folks, This is my first post to the forum. I cannot seem to get my LCD 2004 to work on my Le Potato AML-S905X-CC I went back and forth a few times in armbian-config to enable/disable various items, but as it stands right now, I just have i2cA enabled. The address of my LCD 2004 is at hex 0x27, and I am using GPIO pins 3 & 5 for SDA and SCL respectively, but it doesn't show up in i2cdetect -y 0: root@lepotato:~# i2cdetect -y 0 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- root@lepotato:~# i2cdetect -l i2c-0 i2c Meson I2C adapter I2C adapter i2c-1 i2c DesignWare HDMI I2C adapter Previously I had i2cb enabled as well. I even tried pins 27/28, as well... Nada... What I can say is that I have two of these LCD2004 units and they both work on my Raspberry Pi 4b without problems, on pins 3 & 5 for SDA and SCL. My Le Potato is brand new and I just wanted to tinker with it as an alternative the RPi4b. Here's the diagnostics log: http://ix.io/4c7X I welcome any and all help. Have a nice day! ~Eric 0 Quote Link to comment Share on other sites More sharing options...
