Hello all, I have an interesting issue with my LPC1768 design. I am using the CMSIS libs and the CTL RTOS. I have tasks running via timer IRQ events all the time, and infrequent user external IRQ events. To save power when no active task is running, I put the processor to sleep by calling CLKPWR_Sleep() from main (in ctl main is the idle task). If the user has not done anything after a whil...
