Hello Jan,

Thanks for posting this series. I have some experience with the MSP430 but little with with the MSP432 and none with TI RTOS. I breezed through Parts 1 and 2 but got stuck here. In order to compile, I had to add this.

#include <xdc/runtime/Error.h>
#include <ti/sysbios/knl/Semaphore.h>

Although it now compiles, I don't see any response from the LED. I went to Resource Explorer and imported the TI Echo example to CCS. That example does not use an interrupt. It worked fine and I placed a simple UART_write in the code between the LED toggle in your example above - nothing. I did a quick comparison to see if I missed anything else and the only thing I saw was #include <stdint.h> in the TI code but that did not help. Any ideas?

Regards, Frank

I see that I forgot to add how to write/reply to the USB. Easy:

This looks handy for a way to handle USB tasks.
