The Propeller projects I listed in a previous blog:
PWM based waveform generator
Done, but I'm not going to release it as the limitations outweigh the results. Since the waveform is hardcoded, there's no way to dynamically change volume. There's also no way to internally mix voices onto one channel. And, finally, the sound isn't that impressive. (I was hoping to get something which really sounded like a cello or trumpet.)
single pin NTSC text display driver
Functionally working 100% even without a filtering cap. Now I need to make the hardcoded variables into parameters and calculated values. I might even do a PAL version. Plan is to release this to ObEx.
IF_NEVER timing tests
Complete. All IF_NEVERs take 4 cycles, irrespective of the opcode. It would have been more interesting if it wasn't, but this result merely confirms the datasheet.
Extend NTSC240H to have background tiles too
On hold pending interest (mine and others).
I think my next geek project will be the GH antenna.
