It should be obvious, but I cannot make it working. I have soldered Debolesti's PCB and I can plug my B-5 to Warthog's base - works like a charm. But while I try to connect B-5 to the last TLE5010 in chain it does not regognize buttons. All eight buttons are just red.

Each of three PCBs shares following wires/pins:
- VCC
- GND
- MISO (B3)
- SCK (B1)

Both TLE5010 share B6 as GEN.

CD4021BE uses E6 as CS pin, TLE5010 use B4 and B5 pins for CS.

I have checked circuits from end to end for each wire and all seem to be ok. But it's not. Can you please post your screens how it should be configured?



did you forget what we talked about on page 147 ? smile http://SimHQ.com/forum/ubbthreads.p...uild-your-own-usb-controller#Post4358428

I did the same thing smile on my FLCS ...... use another digital pin for the 4021 PCB as the TLE5010 will override anything else on MISO (data) , see if that works ?



GND ---- Any Available GND Pin
SCK ---- Pin B1
CS ------ Any Available Pin--Assign in MMjoy
DATA --- (MISO) Pin B3 if available but can use any available Digital Pin... eg if TLE5010 PCB are using Miso use any other digital pin (avoid Pin13 or LED will Flash constantly with data flow)
VCC --- 5v Power ( On the Leonardo I use Vin too as Vin voltage = input voltage ie 5v from USB)
