Hi,
I got the display and touchscreen interface working on the STM746 Discovery board with micro python over the weekend.
Have implemented a showPicture command which reads image from SDcard and displays it. I read oneline,display, then read next line etc.
I would like to speed this up by handing off this processing to the underlying C code (possibly even to the DMA engine). Format of SD card is Fat32. Is there a way for me to do this? The only way I can think of is to pass the filename to the underlying C code and let it handle the filesystem and drawing functions.
Is there a better way to do this?
Thanks
Graeme
