nRF52 direct access to EasyDMA

[Shlomo Zippel]

Hello,

Is it possible to use EasyDMA directly with nRF52 SDK without using one of the higher level libraries that use it, i.e SPI / UART? I am interested in implementing something similar to Octows2811.

I also looked at the PWM module for this but it seems like it has a max frequency of 200 kHz which is too slow for what I am trying to do.

Thanks!

Of course you can - it's all documented in the manual - you just set up the registers and let it roll.

Note that EasyDMA has quite a few anomalies on the preview chips, so ensure you're using hardware resources which are actually working.

Ah, that makes sense. Now I'm looking at the correct docs and I see "Decoder with EasyDMA" which is exactly what I need! infocenter.nordicsemi.com/.../Chunk1670748135.html
