How to use Official GUI tool

This software requires a specific CAN to USB module. The official documentation recommends YourCee's USB to CAN module, which supports the serial protocol with a frame header of 41 54 and frame tail of 0D 0A, but this is not readily available, so we searched Aliexpress for an alternative. ※ Note that this will not work for general modules.

Tested(for reference):

Recommended pre-crimped cables

How to run sample

Arduino IDE

  1. Clone MCP_CAN_LIB and cygergear_m5 to Arduino Library directory.
cd ~/Arduino/libraries
git clone https://github.com/coryjfowler/MCP_CAN_lib.git
git clone https://github.com/Locoduino/RingBuffer.git
git clone [email protected]:project-sternbergia/arduino-CAN.git
git clone https://github.com/project-sternbergia/cybergear_m5.git
  1. Open cybergear_m5/examples/control_mode_example.ino with Arduino IDE

    image

    Put this file in the same folder as control_mode_example.ino (for Arduino IDE) If you want to use ESP32_CAN library, please commentin this lines.

  2. Build and write firmware to M5Stack

Sample Code

control_mode_example.ino

Check cybergear behaviour using M5 stack.

  • Middle Button - Change Control Mode (Position Mode -> Speed Mode -> Current Mode)
  • Right Button - Increase control value
  • Left Button - Decrease control value

CyberGear_M5_Control_Mode

cybergear_bilateral.ino

This example use two cybergears for leader and follower. Before you test this example, please change cybergear can id as follows. After that write cybergear_m5/examples/cybergear_bilateral.ino to m5 stack throughout Arduino IDE.

  • leader cybergear : 0x7F
  • follower cybergear : 0x7E

CyberGear_Bilateral
