- messages are 9 bit unpaired
- messages are inverted before be sent
- a start message has to be sent for the synth to see them as valid
I have seen an old Gammon library for 9 bit messages: would it be of some use?
I really need some insight on the form of such messages...
The author of those pages speak about bytes too, so it's not 100% clear to me if every message is 9 bit or some could be 8 bit... Any though?
Thanks. I am waiting for a 6 pin connector to be dropped in my mailbox to start experimenting with this. I will report back!
Another thing of not in the PG200 service manual is that that PG200 *doesn't* use UART, but signals directly from the CPU. I'm a serial noob so I'm not 100% sure if this is important yet but it could be. It sounds a bit closer to *bit banging* than traditional serial communication..
