[Progress]CommonSense controller - better capsense.

I can smell what you guys are cooking, and it's nice and savory!

I don't know yet.

The idea was to use this as a "brains" module with larger "controller PCB" which have sense card interface.
That larger PCB may also have footprint for BLE module + power/battery management circuitry, or just be a breakout board with USB connector and fuse on it (different form-factors using the same module to alleviate current displaywriter controller deficit. Want a displaywriter controller? Order the breakout board on oshpark, solder the brains in and you're done)

..also I need to submit this to PCBA shop and ask them if it's even suitable for PCBA :) Parts may be too close to each other.

TIL four-sided castellated modules are not a thing.
Also that smallest candidate for PCBA is 50x100mm - which means paneling.
And that it looks like castellations can only be done on non-panelized PCBs.

Back to the drawing board, it seems.

Sure they are: https://getchip.com/pages/chippro

... you just have to have enough of an edge for V-score between castellations.

Submitted to PCBWay w/o panelization. Let's see what happens.

TIL those 18x14 "brain" modules will be $10.61@100 units plus shipping (PCBway). [IC] time?

DMA, has the github code been adjusted to the board you're designing, or will it still run on a CY8CKIT-059? I have a custom 4x12 PCB I'd like to use this on.

FletchINKy nope, the github code is for the kit. Currently it's for 8x12 matrix (XTant).
Most probably it will always be the kit (unless I forget and commit the custom version)
Even if it wasn't - switching to the kit is 3 clicks (explained in readme, too).

CommonSense now supports different scanners - namely, ADB and Sun protocols.
So one can make 2 keyboard controllers from one protokit - KitProg can be used as a converter (or for keypad - one can still do 5x5-ish matrix from KitProg :)
