Leyden Jar update and request for help:

So far over 130 F122's and their Leyden Jar controllers have shipped. After some firmware updates the reports are good so far!

Here are some plans for the Leyden Jar controller:

Need help - Split communication between halves, with one half powering the other (for future split ergonomic layouts):

"Well for the moment one half is working but I have trouble making the split feature work. I need time to understand what is wrong with my code: as I have a custom matrix scanning this looks to complicate stuff (all the project I have seen look to use standard QMK matrix scanning). I need to make split working and also try different settings like full duplex (testing half duplex at the moment), various detection of left and right parts"

Rico has kindly published this test code for split communication with the below link. If anyone can help it would be much appreciated to make these controllers even more powerful and useful with various keyboard projects. Rico confirms that the controllers work even with non-capacitive keyboards. https://github.com/mymakercorner/vial-q ... r_impostor

I would like to use a "USB C cable to connect the two ends instead of a TRRS cable" as the latter may result in accidental shorts if the keyboard is powered on during disconnection.

4 layer PCBs:
Using 4 layer PCBs as innovated by wcass to remove the trace area around the PCB, for a smaller PCB (better for the future compact designs mentioned in the Google form above.

PS/2 support:
Rico has started this but it is not yet working. If you'd like this feature and can help, please do! https://github.com/mymakercorner/Leyden_Jar

RedESC please see my previous F122 update post from a couple months ago (March?) regarding the queue and shipping timeline.

Have you ever considered paying people to help you with this shit considering you're the one profiting from everyone's work?

Ps2 daughterboard sounds neat. Great for hooking up to my retro systems.
