     - Communicated with project maintainer about some questions: https://www.pedelecforum.de/forum/index.php?threads/open-source-firmware-fuer-lishui-controller.61113/post-1971427
     - Learned that the throttle and brake level need to be released after the autodetect procedure
     - Added this to the EBiCS wiki: https://github.com/EBiCS/EBiCS_Firmware/wiki
     - Added momentary switch for "brake".
     - Added labels to the headers to avoid having to search online for the pinout all the time.

  • Progress so far

    State so far:

     - Built a wooden stand for the motor
     - Powered the controller and display from RD6024 PSU.
     - Generate a PWM from Arduino to simulate PAS sensor.
     - Blew the RD6024 PSU when the motor stopped getting power and back EMF produced a spike.
     - Repaired RD6024 PSU. Added diode in series to prevent the back EMF from blowing the RD6024 again.
     - Blew the display when the motor stopped getting power and back EMF produced a spike.
     - Depotted the controller for analysis.
     - Figured out to turn on the controller with the SW pin to run controller without display.
     - Replaced soldered connections with 2.0mm female headers.
     - Simulated throttle with potmeter on SPGND, SP5V, SP.
     - Flashed controller with EBiCS opensource firmware.
     - Blew 2 FETs due to running controller without heatsink.
