FX3 PWM duty update issue

[dawa_2529456]

Dear Sir,

I want to output a pwm duty from 1% ~ 99%, but it seems the pwm duty is not predicted, which is also be found in the following!

https://community.cypress.com/thread/17950?q=FX3%20PWM%20duty

I think it may be SDK API bug. when CyU3PGpioComplexUpdate () is called, the timer shall be stopped and cleared ,and then start again according to the new count, just like restart init procedure.

  apiRetStatus = CyU3PGpioComplexUpdate (LED_PWM_PIN, count, CY_FX_PWM_PERIOD);

Can Cypress FAE confirm this issue?

Best，

Hello,

Please refer to this thread Re: FX3 generate varying duty PWM of 120Hz and let me know if this helps.
