Cross Platform Serial programming using Python and PySerial

A short introduction into serial port programming using Python and PySerial Library on Windows and Linux Systems.

• Python 3.8.x language
• Pyserial 3.4 Library

The Python code running on the x86/x64 PC communicates with an microcontroller through serial link (TX,RX and Ground).

• Runs on Both Linux and Windows
• supports only Python 3.x.x Versions
• Added Arduino codes
• Microcontroller used is MSP430G2553 on Launchpad
• MSP430 Codes written in C and Compiled using IAR Embedded WorkBench
• ATmega328P Codes written in Embedded C (WinAVR)
