April 5Apr 5 What should the correctly enabled I2C service (for a 40x2 LCD) look like on Bananapim2pro? Should I edit the armbianEnv.txt file and add, for example, the following entry: overlays=i2c0 i2c1? The armbian-config service is a bit confusing, and after editing it, I get this: ........................ verbosity=1 console=both overlay_prefix=meson fdtfile=amlogic/meson-sm1-bananapi-m2-pro.dtb rootdev=UUID=a4fb8074-c453-45da-ab31-4d61dca46cfa rootfstype=ext4 overlays=i2cA i2cB usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u .................. There are other options, but they probably don't apply to bananapim2pro. : sm1-odroid-c4-i2c0 g12b-bananapi-cm4-i2c2 g12a-radxa-zero-i2c-ao....

April 6Apr 6 Author Solution Thanks for the info to try other options 🙂 Thanks for the tip, I'll try other options 🙂 It worked for: odroid-c4 ... basically, the settings are the same as for the OrangePI3LTS, I'm talking about connecting cables to a 40x2 / 20x2 LCD. The diagram for the BananapiM2pro is as follows: My Winstar 40x2 OLED LCD compatible with drivers: hd44780 / driver: WS0010 is detected in the system as: 3f .................................. sudo i2cdetect -y 0 [sudo] kris: 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3f 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- ..................................
