https://devzone.nordicsemi.com/f/nordic-q-a/92867/what-is-the-maximum-frequency-the-pwm-peripheral-can-be-generate-using-the-nrf52840Hi I have successfully used the TIMER &amp; GPIOTE to generate dual tone frequencies for a BFSK project. 200kHz &amp; 400kHz. ( 50% duty cycle square wave) I wonder if the same is possible using the PWM peripheral. Could you clarify 1) What is the maximumen-USTelligent Community 13Mon, 17 Oct 2022 09:08:50 GMThttps://devzone.nordicsemi.com/thread/390928?ContentTypeID=1Mon, 17 Oct 2022 09:08:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d3b1c38-3112-48f6-a78c-47d020cbdefcKenneth<p>Hello,</p> <p>There is a rather nice discussion here that explain how you can generate&nbsp;sine wave using PWM module:<br /><a href="https://devzone.nordicsemi.com/f/nordic-q-a/89209/clarification-on-how-to-generate-a-10khz-sine-wave-with-pwm-and-dma">Clarification on how to generate a 10kHz sine wave with PWM and DMA</a>&nbsp;</p> <p></p> <p>Indirectly the above should also show how you can generate a 200kHz/400kHz square wave using PWM. Note though that the minimum COUNTERTOP you can use is 3 from the register description:<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/pwm.html#register.COUNTERTOP">https://infocenter.nordicsemi.com/topic/ps_nrf52840/pwm.html#register.COUNTERTOP</a>&nbsp;</p> <p>Also see the PWM chapter in general:<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/pwm.html">https://infocenter.nordicsemi.com/topic/ps_nrf52840/pwm.html</a>&nbsp;</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
