https://devzone.nordicsemi.com/f/nordic-q-a/116532/nrf52832-pwm0-easydma-to-stream-to-ws2812-stringI&#39;m trying to setup an nRF52832 to drive 127 ws2812 by using PWM. It seems the bit-by-bit method is too slow for the 1.25uS period. pwm_set() is using somehow ~5ms, so that is not an option. I would like to use EasyDMA to drive the PWM peripheral oneen-USTelligent Community 13Wed, 20 Nov 2024 15:42:07 GMThttps://devzone.nordicsemi.com/thread/511359?ContentTypeID=1Wed, 20 Nov 2024 15:42:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a6cf99a6-dade-4445-b391-24741e82949bErik de Wit<p>Hi Einar,<br />Thank you, I was questioning the nrfx solution AI suggested yesterday, glad to hear you also recommend that in this case. The device we developed has many functions, including I2S for sound, 2 SPI (one spi for Flash for sound wave and one spi for a&nbsp; peripheral), I2C for&nbsp;other LED drivers.<br />Now I list this, I&#39;m thinking I could try to disengage the I2C for other LED driver (will become&nbsp;unnecessary when the WS2812 work) and setup a 3rd SPI, but first&nbsp;I will try this and let you know if it was successful.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/511316?ContentTypeID=1Wed, 20 Nov 2024 13:48:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8fdeb1fa-e985-45e6-8529-fc0c9257f7b5Einar Thorsrud<p>Hi,</p> <p>We do not have any samples or recomendations for usig the PWM like this. I2S is typically what is used. It may be possible to use the PWM and play out a sequence from DMA, and we have generic samples for that. To get full control you can use the nrfx low-level driver directly, as demonstrated by the samples under zephyr/modules/hal/nordic/nrfx/samples/src/nrfx_pwm/</p><div style="clear:both;"></div>
