- ESP32-C3 AT command set
- For first time use, you need to use Zadig to replace the driver to correctly identify the port.
T-PicoProuses a reversible Type-C design, which corresponds to the port of RP2350 and the USB port of ESP32-C3 respectively.- How to identify the port of RP2350?
- Press and hold the BOOT button on the side of the
T-PicoPro, and then plug in the USB-C. If the computer recognizes it as a disk, then it is the port of the RP2350
- Press and hold the BOOT button on the side of the
- In addition to being a UART, the T-PicoPro
QWIICUART port can also be used as a normal IO - The
QWIICI2C port cannot be used for other purposes and can only be configured as an I2C interface because it is connected to the screen touch and PMU. - The ESP32C3 uses a modified AT firmware that
swaps TX and RX. You can find the custom compilation method of AT firmware here. - ESP32-C3 default AT firmware is compiled in
V3.3.0-dev. The firmware has been simply modified (GPIO control function added), the source code can be found here,Please see commit for specific changes - The T-PicoPro charging indicator light can be turned off through software. If the battery is not connected, the indicator light will flash.
- Install Visual Studio Code and Python
- Search for the
PlatformIOplugin in theVisualStudioCodeextension and install it. - After the installation is complete, you need to restart
VisualStudioCode - After restarting
VisualStudioCode, selectFilein the upper left corner ofVisualStudioCode->Open Folder-> select theT-PicoProdirectory - Wait for the installation of third-party dependent libraries to complete
- Click on the
platformio.inifile, and in theplatformiocolumn - Uncomment one of the lines
src_dir = xxxxto make sure only one line works - Click the (✔) symbol in the lower left corner to compile
- Connect the board to the computer USB
- Click (→) to upload firmware
- Click (plug symbol) to monitor serial output
- If it cannot be written, or the USB device keeps flashing, please check the FAQ below
- It is recommended to use platformio without cumbersome steps
- Install Arduino IDE
- Install Arduino Pico
- Download or clone
T-PicoProto any location - Copy all folders in lib folder to Arduino library folder (e.g. C:\Users\YourName\Documents\Arduino\libraries)
- Open ArduinoIDE ,
Tools, Look at the picture to choose
T-PicoProfolder ->examples->Any Examples- Select
Port - Click
upload, Wait for compilation and writing to complete - If it cannot be written, or the USB device keeps flashing, please check the FAQ below
-
If writing fails successfully,
- Connect the board via the USB cable
- Hold down the (side) BOOT key while holding down the (side) BOOT key and press the (same side) RSTl

How to write ESP32-C3?
- Since the
ESP32-C3reset pin is controlled byRP2350, when you need to update theESP32-C3firmware, please do not include the operation of controlling theESP32-C3reset pin in the program inRP2350. - Press and hold the esp32 BOOT button on the side of the ESP32-C3 module and insert the USB-C.Make sure you are plugging in the USB port side of the "ESP32-C3".The computer should be able to write to "ESP32-C3" normally.

How do I check if the hardware is OK?
- Please follow the first step of the FAQ and drag
firmware.uf2in the firmware directory into the disk. The program includes hardware self-test, which can determine whether the hardware is normal.
