Hello i am italian, i have udoo quand with the os Wheezy, i tried to install the software i2c tools but will not start!!! . I was testing with a PCF8574 (expansion 8bit) collengando on i2c SDA1 and sck1 (pin21,22), can help me how to fix this? at least a little explanation, thanks
Re: information Hi there sgarrupino84, you have to recompile the kernel to expose the I2C from pin 21 and pin 22. If I were in your shoes I'd take a look at http://udoo.org/download/files/Document ... 8_2013.pdf Cheers!
If you just want to test something or ar willing to setup a cable you can also easily use i2c-2 from LDVS plug CN13 Should be Pin 12 and Pin 19 (please check on documentation have non here currently)
