Hi MHanh
I checked out the application list after doing opkg update and looked at the git site.
I am now going through the files on i2c LCD to see if I can get it to work with a generic LCD backpack.
The problem seems to be that it isn't being detected. I2cdetect didn't show the device, which works with AlexT's version.
I'll poke around a bit more this weekend to see what is going on.
thanks
rick
