Po Ting

Here's an example on how to do SPI masters on T4 with DMA. In a non blocking way. I also did a SPI DMA Slave library, but it looks like it's the master that you want here, and then three times in parallel, so SPI0, SPI1 and SPI2 hardware that is...

Wow cool, that essentially gives SPI almost DMA speed but not messing with all the DMA thing Thanks for the tip :) , I don't know we could just attach interrupt with the spi.tranfer() function. Though I just completed the coding to use T4 DMASPI...

It's been a long time and I finally have some time to seek to move my POV project from T3 to T4 I have to redig into old codes and things and test them on T4😂😂 @mercyful : the refresh speed could be higher if you use DMA with SPI, OctoWS2811 with...

I'm using JLCPCB on most of my project, because China is close to me... much cheaper shipping available. I believe PCBway is also located in China, they provide near same service (PCB/assemble/3DP/CNC....) not sure how they are related but...
