Hi everyone here we'll be working on how to get started with RangePi & Load Python File To RangePi And Install Thonny Python IDE
RangePi Introduction:Range-Pi is a low-cost portable “Plug and Play LoRaTM Dongle” based on Raspberry Pi RP2040 and LoRaTM Modules, comes with an onboard 1.14" LCD that covers 433/868/915 MHz frequency band to enable data transmission up to 5 KM.
Use thonny python IDE for programming, link of the software is given below :
Steps to load python file to RangePiStep 1 - Open thonny 📷
Step 2 - Select micropython and port in thonny for this go to run-> select interpreter 📷 📷
Step 3 - Save python file to RangePi 📷 📷 📷
Step 4 - Run(execute) and stop file (script) 📷
Uploading the ST7789 Python Firmware
The firmware includes frozen python font files and pre-compiled objects with the ST7789 C driver for a variety of devices.
- The firmware includes frozen python font files and pre-compiled objects with the st7789 C driver for a variety of devices.
The driver's library is provided as a single firmware.uf2 file, which is accessible here: https://github.com/russhughes/st7789_mpy/tree/master/firmware/RP2

Holding down the RangePi BOTSEL button while dragging this file into the mounted RP2 folder will allow you to load it.
- Holding down the RangePi BOTSEL button while dragging this file into the mounted RP2 folder will allow you to load it.
First, you need to install firmware of 1.14 lcd screen to RangePi, for this press boot button then plug to laptop/desktop after that release the button, you see new storage device. then drag and drop firmware.uf2 file to RangePi
Receiver
- rangepi_receiver.py - Run this file if you make RangePi as a receiver ( in all cases receiver is the same)
