I just got Peca's TinyBOB and USB cover, and with WizardStan's EXT jacks, I can now attempt with the Pandora what I couldn't with the GP2X: A direct connection between my old Atari (actually Indus GT) disk drive and the OpenPandora. After seeing other posts regarding the EXT port, I figured the connections would go something like this:
The reason I couldn't do this on the GP2X is that I need both a RX/TX pair AND another output for the Command line (high to trigger a command) which I can do here with any of a number of lines, but likely the RTS or CTS line.
Some questions:
[1] Should I use the UART2 or UART3 lines? It looks like I should use the UART2 lines, especially because [A] The RTS/CTS lines look like they're with UART2 and Kernel comms seem to run via UART3. But is UART2 ready to use in software/firmware?
[2] Is there a steady 1.8V reference from the Pandora? Can holding a line high provide a reference if the 1.5/3.0V line cannot?
Thanks, and I'll keep you posted on the progress!
