This repo contains code for transmitting and receiving characters (Strings) serially between an x86 Linux PC and a Microcontroller (MSP430G2553 on Launchpad).
Full code explanation along with screenshots can be found here on the xanthium website
The Microcontroller and PC are connected in null modem configuration using 3 signals (TX,RX and Ground).
The code uses termios API's to intialize the PC serial port and transmit a character to the microcontroller board.
- The PC side code is written in C using termios API
- and can be compiled using GCC .
The Code will Work With Standard RS232 Serial ports or any USB to Serial Converter.
More info about the USB to Serial/RS232/RS485 Converter used in the above tutorial can be found here
The Microcontroller side code is written in Embedded C and can be Compiled using Code Composer Studio for MSP430.
The Hardware used is MSP430G2553 on Launch pad development board.
