Is there a forum in your native language here? viewforum.php?f=90
You might find it easier to explain your problem there.
Ok I'll Try with SPI...joan wrote:Both the Pi and the Arduino M0 Pro need to be I2C bus masters. You can't use I2C to communicate between them.
You can use the serial link and/or SPI.
Ok joan, but it could be necessary a level converter to solve my problem?joan wrote:As long as the Arduino doesn't have pull-ups you will be fine.
But in the guides that I followed it was explained that being rpi2 master and slave Arduino not need a level converter because Arduino has no pull-up resistors installed.joan wrote:Probably not.
Is your Arduino 5V? If so will it have 5V pull-ups on SDA/SCL which will kill the Pi?
Sure the wired is this but are a Rpi2 and an Arduino M0 proDirkS wrote:Is anything connected on the i2c bus?
If so, what is it and is it wired correctly?
