How would it help someone else? If you've got a faulty board, send it back for a refund/replacement. Posting here won't fix it.Yes I saw that. As I said, I posted because my bad boards seem to be from the same batch and gave the id number from the boards in the hope it would help someone else.
BBC Basic can write them at 20MHz. How fast do you need them to be?This thread was about connecting a Pi physically to the BBC's Tube port, which is basically the 6502 bus. You can not read and write the Pi's GPIOs anywhere near fast enough to use them as a 6502 bus.
See thread at:Before I go and splash out any cash, does anyone know if you can access the GPIO pins on a Raspberry Pi via BBC BASIC via RISC OS?
