    Bionx controller options?

    You definately have a canbus system. The silkscreening on the board labels some pins cl and ch - CanHigh and CanLow I expect that the BMS board is destroyed. My suspicion is that one or more traces in the PCB are cracked, possibly in an internal layer and the CPU no longer gets the right signals.

    Bionx controller options?

    I have had more than one request for the code I generated as a result of this project. This is written for the arduino to simulate a console. It tries to use the strain gauge to set the power command, similar to the console It does not require a Bionx battery to work, however if a Bionx...

    BIONX motor controller revealed

    I'm looking for advise or suggestions on repairing my P250 motor. I have a 2004 P250 bionx motor that started acting erratic after riding in a very heavy rainstorm. I pulled it apart and found standing water inside. It probably came in through the axle. I've been trying to repair it using a...

    Bionx controller options?

    Turns out the Bionx I2C motor has a pretty short register list. Recall it is device 8. The following registers are read from: 17 - rotation speed (read about a dozen times per second) 18 - unknown. read about once every few seconds 20 - motor loading (frequently read) 21 - strain...

    Bionx controller options?

    I've been working reverse engineering the I2C setup myself this weekend. Using an arduino uno as a i2c snooper. I see that: - the console is the master (no surprise). - the motor is address 8. - the battery pack address 9. - turning the battery pack on is done by temporary shorting the...

    Bionx controller options?

    The newer CanBus motors can be driven by an arduino setup. This fellow did some good investigation into reverse engineering the protocol and writing some code http://www.northerndtool.com/bionx I find myself short a CanBus battery for my setup, so I am working on building a bionx compatible...
