I understand, there is still a lot of work to do, but you made an amazing start!
I might have a look at the PCM stuff, since I previously developed some Apps for streaming WiFi cameras with video/audio ( a couple different audio codecs but PCM was the simplest). I saw on your block diagram (from the LCD article) the audio pins on the A64. But how would I find more information on how the microphone is connected, and how those pins relate to the modem chip you described in another article with the PCM configuration information? Or maybe I should start with something more simple like switching a led on/off
But it seems like you have an amazing inside view into how everything is connected. I downloaded the A64 user manual, but I dont think that has enough info, and the AT modem document, also only tells a part of the story.Regarding the feature-phone demo, I noticed that the old blue/green/red test pattern flashes briefly on the PP before the keypad displays. I seem to recall this was one of your display driver experiments
but I cannot find the code that is drawing that pattern... can you give me a pointer please?
