ocapi
C-level driver collection for MSP430 and derivatives
ocapi is an open source driver collection for MSP430 and derivative processors. It provides a C language application programming interface (API) for deploying individual processor capabilities. Current modules support serial communication via UART, I2C and SPI, digital I/O (GPIO), analog-to-digital conversion (ADC), Timers and so on.
ocapi aims at being independent of the development host platform.
