Hey, techies! Ready for a feast of torque and creativity? Today, we're going to take you on a journey to explore the fantastic linkage between M5Stack Basic V2.7 and Xiaomi's Cybergear to instantly 'move' your projects!
H/W Components (ESP32 + CAN Transceiver Unit)
-
XT30(2+2)-F
-
Grove Cable
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.
How to run a sample
Arduino IDE
-
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 git@github.com:project-sternbergia/arduino-CAN.git
git clone https://github.com/project-sternbergia/cybergear_m5.git
-
Open cybergear_m5/examples/control_mode_example.ino with Arduino IDE
-
Put this file in the same folder as control_mode_example.ino (for Arduino IDE)
-
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_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
