WebI was curious whether you could run interrupts within Energia code on the TIMSP430 – guess what? You can. Here’s some code that toggles the Green LED during an interrupt service routine. The RED LED is toggled in the main program loop. The code runs on the MSP430 Launchpad with the MSP430G2553 microcontroller. 1. 2. 3.

WebOct 4, 2024 · The TI user guide says "Any access, read or write, of the TAIV register automatically resets the highest pending interrupt flag" for it. Since your code does not read (or write) to the TAIV register inside the interrupt routine, then it will be stuck with the interrupt flag set but never clearing, so then it will never retrigger again.

WebJul 12, 2014 · The 8051 has five interrupt resources. Each of them can be programmed to two priority levels. The interrupt sources are: INT0 – Interrupt from external request to P3.2 of 8051. Timer 0 – This interrupt gets activated whenever Timer 0 activates the Flag TF0. INT1 – Interrupt made from external request to P3.3.

With interrupts you don’t … WebAn interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. Whenever an interrupt occurs, the controller completes the execution of the current instruction and starts the execution of an Interrupt Service Routine (ISR) or Interrupt Handler.
