Hello, I tried to connect an i2c 'arduino-compatible' display to an a10s olinuxino and it kind of does not work. Some command sequences make it display something but definitely not what was sent to it.
It works when connected to Arduino UNO wired directly to either of 5V or 3.3V, gnd, A4 and A5. It has been pointed out that i2c is supposed to be terminated which is something that the Arduino library possibly sets up on the board. Is it possible to use internal i2c termination on sunxi hardware with Linux 4.0 and how is it set up? I could probably set up something in DT if this was permanently installed on the board but normally i2c is accessible from userspace so I would prefer to set up termination if and when I use the pins for point-to-point i2c. afaict the gpio documentation says this is 'hardware specific' Thanks Michal -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
