Overview

MSP430-FUNCTION-CODE-EXAMPLES is a collection of 25 code examples for use with the MSP430FR2000, MSP430FR2100, MSP430FR2110 and MSP430FR2111 Value Line Sensing microcontrollers (MCUs). These code examples allow developers to add programmability to simple digital and analog functions such as timers, input/output expanders, system reset controllers, EEPROM and more. The majority of the code examples fit in under 0.5KB of memory in the MSP430FR2000 MCU with a few using up to 1KB of memory to operate.

The code examples were tested using the MSP-T430PW20 target development board and MSP-FET programmer and debugger board. However, the code examples can be easily modified and ported to the MSP-EXP430FR2311 LaunchPad™ development kit – a lower-cost evaluation platform than the target development board. See this code portability guide for more details.

The provided function code examples can be modified using Code Composer Studio™ (CCS) or IAR® Embedded Workbench integrated development environments (IDEs).

Release Information

MSP430-FUNCTION-CODE-EXAMPLES is a collection of code examples for use with the MSP430FR2000, MSP430FR2100, MSP430FR2110 and MSP430FR2111 microcontrollers. The code examples downloads are grouped in the following function categories: Communication, pulse width modulation, system and housekeeping, and timer. A 2-page Tech Note is linked in the description field of each function and all of the Tech Notes for these functions are also available in an e-Book format.

The code examples were tested using the MSP-TS430PW20 target development board and MSP-FET programmer and debugger board. However, the code examples can be easily modified and ported to the MSP-EXP430FR2311 LaunchPad development kit - a lower-cost evaluation platform than the target development board. See application note SLAA812. For tips and tricks on optimizing C code for size see application note SLAA812.
