3. Go to Tools->Boards->Board Manager in the IDE
4. Type "pico" in the search box and select "Add":
5. Copy TFT_eSPI to the <C:\Users\Your User Name\Documents\Arduino\libraries> directory
6. Open Arduino IDE, find TFT_eSPI in the file and example, the T-Display factory test program is located at TFT_eSPI -> FactoryTest, you can also use other sample programs provided by TFT_eSPI
7. In the Arduino IDE tool options, select the development board Raspberry Pi Pico, Other keep the default
8. Hold down the BOOT button, click the reset button, and release the BOOT button after a delay of one second or after waiting for the computer to eject a new disk
9. Finally, click upload or drag the firmware to the new disk

3. Press the BOOT button, click RES, then go back to Thonny Python IDE and change the port to the serial port where Pico is located. If you don't find it, click Install or update firmware.
4. Enter or save as a script to run

from machine import Pin, Timer
led = Pin(25,Pin.OUT)
tim = Timer()
def tick(timer):
    global led
    led.toggle()
tim.init(freq=2.5, mode=Timer.PERIODIC, callback=tick)

5. If you need to save to the chip, you need to click File->Save As->rp2040.

6. For more usage methods, please refer to the Micro python documentation.

ESP32-C3 Upload method

• ESP32C3 mainly uses ESP32-AT firmware here. If you want to use it as a coprocessor, you can modify the firmware.
• Method 1: if the serial port is displayed with the word jatg when connecting to USB, you can upload it directly using USB. (please note that do not use USB pins to define other functions, otherwise it will be troublesome to upload next time).
• Method 2: (if there is no serial port when connecting ESP32C3 USB) disconnect USB, short connect ESP32C3-IO9 and GND, and then reconnect USB (note that ESP32C3 device is selected to connect USB).
