Can we handle 4 parallel interrupts in TM4C129?

Srinivas Mula

Dear All,

Can we handle 4 parallel (PWM) interrupts in TM4C129? If yes i need steps to initialize the interrupts. Is there are any conditions to be followed here.

Also need two different interrupts on PWM0 for pins PF0 and PF1. Likewise for other PWM's

Hello Srinivas,

When you say "4 parallel interrupts", do you mean an interrupt from each of the PWM generators? If so, then yes you can do that.

The PWM driver in TivaWare has APIs that should help in configuring the interrupts. Also the sections "Interrupt/ADC-Trigger Selector", "Initialization and Configuration" and "Register Description" in the "PWM" chapter of the datasheet should have useful information.

Thanks,
Sai

Hi Sai,

I mean 2 interrupts for each PWM generator? (PWM Generator 0 - PF0 (PWM0) and PF1 (PWM1) ). Likewise for other generators.

Hi All,

I need to generate two different interrupts on pins PF0 and PF1 using PWM Generator 0. Is it possible?

Hello Srinivas,

Yes, it is possible to generate interrupt on the pins PF0 and PF1 when using the PWM Generator 0. Configure the PWM and the PWM pins as required. To be able to generate interrupt on the 2 pins, an additional configuration of the GPIO Port F needs to be done. This additional configuration is configuring the GPIO Pin Interrupt and enable of the GPIO Interrupt to the NVIC. When the PWM toggles the pin, then based on the interrupt edge, the GPIO interrupt Handler shall be invoked.
