Lishui Controller Programming Info

To program a Lishui controller, you typically use a dedicated USB programmer and the official LSH_File_Update_Tools software. This allows you to flash firmware files (with a .lsh extension) or adjust critical parameters like current and voltage limits. 🛠️ Hardware Requirements

Open Source Alternatives: Projects like EBiCS_Firmware and the Flexible OpenSource Firmware allow you to bypass factory restrictions. These often require an ST-Link V2 programmer to connect directly to the controller’s internal STM32 pins. lishui controller programming

Lishui controllers (LS), manufactured by the Nanjing Lishui Electronics Research Institute, are widely used in e-bikes for their smooth Field-Oriented Control (FOC) performance. Programming these units allows riders to fine-tune torque delivery, adjust current limits, and even install custom open-source firmware. Essential Programming Tools To program a Lishui controller, you typically use

  1. Patch the original firmware bin file using a hex editor (search for hex values corresponding to speed limit—often 0x19 = 25km/h).
  2. Flash the patched bin via ST-Link.
  3. Perform a "relearn" procedure: power on, hold throttle full for 5 seconds, then release. The controller auto-detects motor hall angles.
