Display lib rewrite - use DMA.

Open piodabro opened this issue 7 years ago • 3 comments

The display lib is based on Adafruit Arduino library. It uses synchronous I2C. It should be rewrited to use DMA.

It needs some more work on nonblocking display calls. Implement double buffering?

Hi, isn't that issue solved in v0.9?

Hi, it has been solved partially. It still needs some work to make display lib fully DMA dependent. Now only image memory is written via DMA, commands are sent synchronously. Lib need a rewrite to make it working more asynchronously using DMA and DMA interrupts.
