Hi,

I am using the SparkFun\_Serial\_Controlled\_Motor\_Driver\_Arduino\_Library. I used it with Arduino UNO and it worked perfectly. But when I tried to run it with Sparkfun’s SAMD21 Mini, I faced a problem with the myMotorDriver.begin() function. The code stops at this line and doesn’t go to the next line. I checked the function definition but I couldn’t find whats the problem. Could anyone help me with this? Am I having a problem with including the SCMD library in SAMD21 Mini?

Bests,

Can you give us more information on what you are doing? Ie - what I2C vs SPI? Are you using an example?
