MSP430 LaunchPad Tutorial - Part 4 - UART Transmission
Still RelevantIntermediate
Today we are going to learn how to communicate using UART with the Launchpad. For this purpose I will replace the default microcontroller that comes with the board with the MSP430G2553. It is the most powerful device in the MSP430 Value Line and...
Summary
This tutorial shows how to enable UART communication on the MSP430 LaunchPad by swapping in the MSP430G2553 and configuring its USCI peripheral. The reader will learn register-level UART setup, baud-rate calculation, and a working transmit/receive example to connect the board to a serial terminal.
Key Takeaways
- Configure the MSP430G2553 USCI_A0 registers for UART transmit and receive
- Calculate and set baud rate using the MSP430 clock sources (SMCLK/ACLK) and divider registers
- Implement both polling and interrupt-driven TX/RX routines with example code
- Connect the LaunchPad to a PC serial terminal and verify communication with practical tips
Who Should Read This
Embedded engineers or hobbyists with basic MCU experience who want to add serial communication to MSP430 LaunchPad projects and understand register-level UART configuration.
