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.

There are no underlying EasyDMA registers, there are various peripherals which use EasyDMA and you access EasyDMA via their registers for that peripheral instance. By 'higher level libraries' did you actually mean 'hardware peripherals', because they're rather different concepts?

No you cannot use EasyDMA outside of a hardware peripheral.
