Automated release for MicroPython.

What we get here:
micropython.bin, bootloader.bin and partition-table.bin plus firmware.bin that is all 3 .bin in just 1

Instructions

You need to have some dependencies pre-instaled in your OS:

Python 3
Pip
Python VENV

Windows or Linux:

Create Virtual Environment

python -m venv esp-env

On Windows activate Virtual Environment this way:

.\esp-env\Scripts\activate

On Linux activate Virtual Environment this way:

source esp-env/bin/activate

On Windows or Linux install esptool:

pip install esptool

Put ESP32 C3 in BOOTLOADER MODE:

With USB cable on USB, press BOOT button then RST button, release RST, then release BOOT button. Or unplug, press BOOT button meanwhile you plug in the usb port on PC or SBC like a Raspberry Pi.
Alternative: Use Thonny IDE, plug your ESP32-C3, on Thonny Shell type:
```
from machine import bootloader
```
Press Enter then type:
```
bootloader()
```
Press Enter then just close Thonny and go to Terminal with Virtual Environment activate.

Erase Flash:

python -m esptool --chip esp32c3 erase-flash

Then Flash:

Put 3 binaries in the same folder you are executing the steps, example Downloads folder, you need to be in that folder where are the binaries.

python -m esptool --chip esp32c3 -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size 4MB --flash_freq 80m 0x0 bootloader.bin 0x8000 partition-table.bin 0x10000 micropython.bin

If you use the firmware.bin then:

python -m esptool --chip esp32c3 --baud 460800 write_flash 0x0 firmware.bin

NOTE IN WINDOWS:

If you get a PowerShell Scripts Policy Execution Exception that don’t let you activate the Virtual Environment:
Then open a Terminal like Administrator and type:

Set-ExecutionPolicy Unrestricted

Close the Terminal now you can activate the Python Virtual Enmvironment
