The coolest stuffs for MSP430s are TI’s MSP430Ware driver libraries (driverlib) and GRACE. Driver
libraries remove the pain of traditionally coding MSP430s using registers. Driver libraries provide easy-
to-use API functions for configuring MSP430 peripherals just like the Standard Peripheral Libraries
(SPL) of STM8 micros. However, these libraries are only supported for the newest and resource-rich
MSP430 microcontrollers like the MSP430F5529LP. This idea of driver libraries is quickly gaining mass
popularity and is becoming standard day-by-day for all modern era micros. MSP430Ware can be
downloaded for free from http://www.ti.com/tool/mspware.
You can use TI’s Resource Explorer to check out what’s in driverlib and if your target MCU is supported.
GRACE, on the other hand, is intended for relatively less-resourceful micros like the MSP430G2231
that are mostly well-suited for lower level assembly language environments. GRACE is basically a
