Hey guys
Its my first post here so hello
Me and some friends are working on a project where we want to make our DE0-Nano FPGA communicate with Arduino Uno micro controller over i2c bus. We want to send bits of information to the Nano.
My question is; is it at all possible. I guess you can use the SDA and SCL pins from UNO directly to the GPIO pins on the Nano? The voltage problem is solved since Uno is slave and FPGA master, and the UNO has pull-up resistors so active high would be 0V and low 3.3V?
And if it`s a repost let me know
