Hi Dave, Thanks for providing the part numbers. After looking at the datasheet for the MSP430F133 device, it has dedicated JTAG pins that can't be reconfigured as GPIO (general purpose I/O) pins unlike...

Hi Ryan, Thanks for all the help so far. Currently I broke up i2c_init() and created a new function read_init() which would take place after nunchuck_init(), which will reset the UCTR bit and set the...

Hi Ryan, I have made some progress. I now have a Non-RTOS app that I can make work and not work by changing the value of __SYSTEM_CLOCK, from 3000000 to 12000000. I am trying to figure out how that...

I honestly do not know, having very little TI-RTOS experience myself. It might be worth asking the TI-RTOS Forum. Regards, Ryan

Hi David, While debugging the code I found two things. 1. Every 2nd SPI communication is missued 2. Data received on the slave is right shifted by 3 for all data. Don't understand why this could be...

Link to this thread if desired, but in the end the new topic (changing MCLK frequency in TI-RTOS) is unrelated to these efforts. Regards, Ryan

You could be using low power modes improperly or your clock init fails when running w/o debugger. Do you use any low power mode? If yes, then try not using LMP and see what happens. Also add like 1sec...
