Setup RP2040 HAT Expansion

It Support C/C++, MicroPython and circuitpython

1. Download Thonny IDE

   https://thonny.org/

   

2. In RP2040 HAT Expansion we can use both MicroPython and CircuitPython, but we use micropython ( use micropython * )

   • Install Micropython in PiSquare first you need to press the boot button of RP2040 HAT Expansion, then connect the USB, don,t release the button until you connect the USB to the laptop. then you see a new device named "RPI-RP2".

     After this go to run->select interpreter,choose device,port and install micropython (install firmware)

   Or drag and drop the firmware "rp2-pico-20220618-v1.19.1.uf2" to RP2040 directory

   • Install CircuitPython in RP2040 HAT Expansion Insert the circuit python to the PiSquare(it is circuit python firmware "adafruit-circuitpython-raspberry_pi_pico-en_US-7.1.1.uf2"). for this first you need to press the boot button then connect the USB, don,t release the button until you connect the USB to the laptop. then you see a new device named "RPI-RP2" drag this file "adafruit-circuitpython- raspberry_pi_pico-en_US-7.1.1.uf2" to this device as shown in figure: this is the official website, or you can download from here https://circuitpython.org/board/raspberry_pi_pico/

     When you properly insert the circuitpython then you see a new device that looks like the below image:-

     After this go to run->select interpreter,choose device and port
