ODrive is a high-performance servo motor drive module launched by M5Stack, based on the open source motion control solution ODrive. Supports the control of a single three-phase servo motor, the peak drive current can reach 5A. It has high-speed motor control capability while providing encoder signal interface, which can realize high-precision motion control positioning. The module uses UART communication interface and is compatible with the official ODrive configuration tool and protocol (you can also configure different motor motion modes through the host computer tool to make the motor work more smoothly and stably).

Remark: In this case, the ODrive module is used to control the high-speed and precise rotation of the servo motor. Press button C to calibrate (do not touch the motor shaft during this period), long press and short press button A to control the motor rotation. Note: The motor parameter configuration in this case is only applicable to the motor model matched with the M5 Odrive kit. When driving other types of motors, please configure the parameters according to the motor used.

odrivetool is the configuration and debugging software for ODrive, through which the motor parameters can be configured. This tutorial will demonstrate the installation and basic use of odrivetool under the
pip3 install odrive==0.5.1.post0
~/.local/binto the system environment variable, execute the following command, and insert
export PATH=$PATH:~/.local/binto the end of the text.
odrivetoolfrom the command line to run the tool. Connect the ODrive module to the computer and wait for odrivetool to recognize it. After successful connection, enter
odrv0.vbus_voltageto test and obtain the power supply voltage of the drive board.

Execute the following statement in Setup() of the Arduino program
When M5Core2 is stacked with other M5 modules, you need to remove the battery base of Core2, which does not support module stacking.
Reason and solution: The power supply current of the port is insufficient, which can cause the device to not enter the download mode normally. You can try to connect a capacitor (>0.1uF) between the RST pin and the GND pin, or when uploading the program, set the G0 Short-circuit to GND, so that G0 can be set to a low level state normally
Add the header file #include <driver/adc.h> and the function adc_power_acquire(); in the Arduino program
The battery life of the controller is affected by various factors such as battery capacity, operating status, and load, so there is no fixed value. Reducing the load and adopting a sleep strategy can effectively increase the battery life.
Support multiple stacks, the total capacity of the batteries in parallel increases, and the voltage remains unchanged. However, since the discharge of each battery is not balanced during use, there is a voltage difference between the batteries, which may cause the battery to charge backwards. .(will lose part of the battery capacity)
ESP32 module currently does not support WiFi in 5G band, only 2.4G.
Confirm whether the TX/RX pin on the TTL side of the pin is correct, try to add two 120Ω terminal resistors at the beginning and end of the device line to reduce signal reflection interference

Use esptool to read the flash content of esp32 and export the bin file. Refer to the detailed operation
Restart the Arduino IDE, the computer uses the mobile AP mobile network to download.
Refer to the Github link below, use arduino-esp32fs-plugin for file upload
Check if the COM of the corresponding device is selected and if the M5Burner is the latest version
UIFlow users can switch the Label font to Unicode, Arduino users can use the Chinese font library provided in the M5GFX driver library
Confirm whether the SD card format is FAT32, and no partitions exist.

STAMP C3U enters program download mode operation: 1. Long press the center button (G9) of STAMP C3U when the power is off. 2. Connect to the computer, after the port is successfully identified, program burning.
By default, USB CDC is not enabled, the serial port output started by C3U will be output through the default pins (G20, G21) of UART0. If you want to output through USB, please use the IDE to output Its USB CDC option is enabled. (Arduino users can enable it through Tools->USB CDC on Boot-Enabled. For IDF users, please refer to the ESP IDF official documentation.)
Refer to the UIFlow documentation of the corresponding device to check whether the device has entered the USB programming mode.
Make sure that the NBIoT used is not locked. Frequent device replacement or after activating the IoT card, using traffic in different places may cause the card to be locked. If the above situation occurs, please contact the IoT card supplier. If you are using the IoT card matching M5, please contact M5 after-sales through e-commerce or email. (provide the ICCID of the IoT card)
Describe the problems encountered in detail. Screenshots of the programs involved or files can be added as attachments and sent to M5Stack's official after-sales email
