LPC824-MAX board ...
I expanded the sample code for file "periph_i2cm_interrupt" to setup and use all I2C ports in interrupt mode. (LPCOpen does not provide sample code for the non fixed I2C port.) Only I2C0 causes an interrupt. I get no activity on the other I2C ports. I studied the user manual in effort to determine what possible step I am missing. When debugging, after loading the MSTDAT register and the start command in the MSTCTL register, the STAT register is always "0".
Is there a sample code for seting up the other I2C ports?
