Ok, so I've changed over to an MSP430G2553IRHB32R Controller. This is in the QFN 32 pin package. According to it, P1.6 is for SCL I2C and P1.7 is for SDA I2C. On the 20 pin board, they are pins 14 and 15. On the 28 pin board they are pins 22 and 23. On the 32 pin board they are pins 21 and 22. So, I'm trying to use the simple I2C Scanner and get nothing. I have 2 I2C devices attached, but cannot see either of them. There have been many posts about inserting a Wire.write(1); command and copying updated files into the system. I'm using the latest Energia 18 on a Windows 10 ma
