  1. I'm working on a reflow controller with a G2553 driving a solid state relay to control power. It also includes a rotary encoder with push button and two 7-segment displays to adjust and display the duty cycle. I've written it in assembler, and all of the activity takes place within the interrupt service routine triggered every 2ms by the watchdog timer in interval timer mode. Between interrupts, the processor sleeps. In assembler, the service routine does its magic in about 0.1ms, or 1/20th of the total time, so there's no danger of an overrun into the next trigger. There are no pin inter
  2. All, Here is me again struggling with the timer. What I am trying to do is count to CCR0, passing through CCR1, generating interrupts when timer overflows and when it reaches CCR1 value as well. From TI examples I had understood I should set up something like this, adding code to the appropriate "switch" cases: #pragma vector=TIMERA1_VECTOR __interrupt void Timer_A(void) { switch( TAIV ) { case 2: break; // CCR1 not used case 4: break; // CCR2 not used case 10: P1OUT ^= 0x01; // overflow b
