Thanks to all for this incredible source! I am very new to all this but want to make the jump after reading all this thread and others. I have just received Pro Micro clone but still need to get a few things. Eventually I plan to attempt rudder pedals with a number of additional buttons. However to learn the process I am starting slow. Step 1 is to make a simple box with 4 buttons a Pot and Encoder (the last 2 are just for learning as I have no plans for them yet). Step 2 will be to add another 16-20 buttons with either matrix or Shift Register 74HC165.
Some questions: When I add the extra buttons in Step 2 do I need to do a re-set of board so that it adds them? I know that a matrix needs Diodes like 1N4148. But I am getting mixed up with Shift registers. Some posts say no Diodes but example in the Wiki seems like it has some. For a Parallel In Serial out Shift Register is all I need the 2-3 IC's and a PCB? What is best way to obtain a PCB for Shift Registers?
Thanks
You don't need to reload the Firmware it is only done once (unless it gets an upgrade by Mega-Mozg) you just reload the "sets" with the "load sets to device button", very fast and easy. When you restart MMJoy you can also "Load Sets from Device" if needed
I'm very new too , so not sure about the Shift registers as my FLCS already had them (4021 type) in the Handle Originally.
One of the members here Debolitis? has an OSH webpage for them already made and you can just order them in several types to suit your needs.
