MSP 430 Embedded Software
Real-Time Operating Systems (RTOS)
A real-time operating system (RTOS) is a multitasking operating system which uses specialized algorithms to schedule and guarantee deadlines of tasks. Key features of an RTOS include minimal latency for task switching and the number of tasks it can handle. Third party RTOS that are compatible with the MSP430 minimize memory resources needed to support the RTOS, making them ideal for embedded solutions.

MSP430 16-bit Microcontroller Code Examples
Code examples are available for every MSP430 device that configures each of the integrated peripherals for various application needs. Each zip file below includes both C and assembly code examples that can be directly imported into IAR or CCS. Developers may use the code examples "as-is" or modify the various code modules to jumpstart custom applications. Check the readme to see the complete list of available code snippets along with brief descriptions. Please read applicable section under terms of use prior to utilizing any software. Happy coding!
