Efficient way of generating a differential square wave

[Ros]

What is the lowest power consumption method of generating a square wave, less than 100 kHz, and with a differential (or complementary) o/p?

Is it better to use PWM or driving GPIO directly?

Hi,

Thank you for reaching out to us with your questions.

I believe it would be more practical to measure and compare the two solutions directly to assess their performance in your specific application.

Additionally, regarding your application’s PWM accuracy requirements, I recommend using the Zephyr PWM API instead of a GPIO + Timer/Delay solution, especially since you also require differential output.

Best regards,
