I have been trying to get the pmodIA working with the chipKIT uC32 using MPIDE 0150. After hooking the I2C pins on the pmodIA to the uC32's dedicated I2C pins on J11, Vcc to 5V or 3.3V, etc. , successfully uploading the example sketch to the board and running the IA_Test() function, the session fails to proceed upon trying to interact the pmodIA. I downloaded and installed the associated libraries and such about a week ago. Here is what I've been getting on the serial monitor: PmodIA Demo Press 'r' when ready!! IN test 128 Then nothing else happens, presumably due to the code trying to execute the setRegisterPointer(uint8_t RegAddress) function which I think is the first part involving communication with the pmodIA. Has anyone else been having this issue or has anyone been able to get the two devices communicating? Any ideas on what might be causing it? Thanks in advance.
