Hi all,

I would like to ask for a bit of help to soft out my troubles with my ancient old arch enemy - the I2C bus :)

My setup is this: a 29566 device acting as a master, and using the P1[5] and P1[7] lines. I managed to successfully run a I2Cm module and verify the communication. However I need 400k speed and trying to use the I2CHW module instead. Just repeating the example code for a single master device and it always hangs on this line:

I also tried the option:
while(I2CHW_bReadI2CStatus()&I2CHW_ISR_ACTIVE);, again with no success.

Don't know what to try next...
