kd21c lcd display quotation

The Limited Warranty is expressly limited to the replacement of a defective lithium ion battery (the “Battery”), frame, forks, stem, handlebar, headset, seat post, saddle, brakes, lights, bottom bracket, crank set, pedals, rims, wheel hub, freewheel, cassette, derailleur, shifter, motor, throttle, controller, wiring harness, LCD display, kickstand, reflectors and hardware (each a “Covered Component”).

. After entering the code (8018), the display only allows you to change three support levels (Eco Normal Power) and to select the voltage 36 or 48V. Lockdown speed and wheel diameter are not accessible.

Without a message from the display, nothing is sent from the controller. If you put the switch-on signal on the supply voltage, the controller uses the last setting and also works without a display.

Next I grabbed a microcontroller (Teensy) and changed the messages coming from the display to the controller so that when I selected level two, I sent it to controller 6 at 36km / h maximum speed .
