Hi,

I am able to generate pwm using n2het1, but next challenge what I have faced till now, How to disable the pwm generation.

I tried gioPORTA[5], but failed to see in debug mode(I mean pwm is not stopping)

pwm generation n2het1[25], disable using gioPORTA[5]. I have enabled gio and het1 driver, pinmux is checked in both cases, pin 5 taken as input, het25 as output, interruput enabled pin5

Thanks

Hi,

Yes. Holding the pin nDIS low will disable all NHET output pins. The PIN_nDIS signal for the N2HET1 module comes from the GIOA[5] terminal.

Another way to disable the PWM is to call pwmStop() function generated by HALCoGen.
