Is there any way for Orin platform to send PWM pulses using normal GPIO

Ordinary GPIO is required to send PWM pulse.

Trigger the camera synchronously!!

Is there any quick way?
Or need development drivers?

hello JiaZW,

may I know which pin you’re going to use? had you configure it through pinmux spreadsheets to select as PWM function?

UART4_TX(GPIO3_PH.03) or GPIO15( GPIO3_PAC.00)

I have a question: can other GPIOs be configured with PWM mode?

hello JiaZW,

those two pin are not able to used as PWM. only pins with GP_PWM* able to configure as PWMs.

Now I need to use these two GPIOs to send 10-30Hz synchronization pulses to the camera. Is there any way?

I used GPIO to simulate pull-down, but the drawing was unstable

hello JiaZW,

the GPIO numbers has changed since k-5.10 have different allocation ranges.
please see-also Identifying the GPIO Number to confirm you’re using correct GPIO numbers to controls the pin.

GPIO is not wrong ;

I just can’t find a way to send pulses stably using GPIO

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

hello JiaZW,

may I know what’s the actual failure, don’t you have code implementation to toggle pin as high/low?
