I had previously ordered 2112 chips but, as they were delayed I paid an extortionate amount for a UK supplier - they were late and ended up coming today - the same day the delayed ones arrived so now I have two sets! Ready for my PCB as well
I just wish I could get the latch to work to know we have the circuit correct - I have spent a good part of the evening on and cannot see why it does not work - maybe my latch chip has a fault... but, I have been programming a lot on the board and it all works as I would expect so at least the circuit and the switches are correct.
