Re: boards and kits and stuff

If I were going to start over, I might consider the Raspberry Pi. It has the memory resources and clock speed to pull it off and a 10" 1024x600 display is less than $50, so overall it costs less than the Discovery board. What I don't know is the programming and library support for C. Python appears good, but the job would be easier in C. Farhan's sBITx uses an RP, so he would know about the development environment better than I would. Perhaps he can jump in and talk about deubgging and library support.

I've thought about looking around for a Teensy equivalent which has a debugger.? The Teensy audio libraries would be missed.
I spent about a month working with the STM32H747I-DISCO Discovery board.? It has good debugging capabilities.
My goal was to get a mockup of the T41 code running on the dual core processor, with DSP on the M7 core and the display on the M4.? I got basic stuff working as planned on the two cores, but good library support didn't make things easy. I finally gave up after determining the display code would require a major rewrite.? Even though the display resolution was the same as the one we use on the T41, the library support was very different.? This will be a bit of a hurdle for those wanting to move to another display type, though not insurmountable.? I have a with a version of the T41 display written in C#.
