Not sure, I have measured the continuity of every single connection, and everything seem to match the documentation I have.perryscope wrote: ↑Aug 05 2019 3:59pmcnrd wrote: ↑Aug 05 2019 3:32pmHey something hit me, should Rx and Tx be swapped?perryscope wrote: ↑Aug 05 2019 10:15amYes 'Vin' on the TSDZ2 is the pin that detects the full battery voltage and turns on the motor as a result, Bafang name this 'PL'
You should see full battery voltage on this wire when the screen is switched on.
As in TSDZ2 brow wire to bafang green and TSDZ2 yellow to bafang yellow.
You can try that but the fact you said you were seeing the data from the motor sensors. (cadence and torque) would suggest the serial coms are working fine. is that definitely the case? i did have issues with tx and rx wires being wrong on my screen but it would not get past showing all the lcd elements showing.
maybe its posible you have one way serial motor to screen?
My guess at this point is that I somehow damaged the KT-LCD3 when I soldered on the connector, I may have shorted some of the pins.
I'll probably try ordering another display, as everything checks out in the cabling.
