Mutex Semaphore - a specialized semphore (compared to a binary semaphore) which is specifically used to protect critical sections of code for multi-thread safety - this semaphore is used to guarantee mutually exclusive access to a shared resource such that only one thread may access a common resource at a time - with shared memory this prevents data corruption that could be caused by multiple readers/writers - e.g. if a writer has partially updated a shared data structure, is preempted/interrupted, and then a reader accessed the partially updated data, the data may be completely inconsistent.
Nand Flash - a flash memory device which is normally erased to all F’s and writes are bitwise masked in with an and operation.
NCD SCAM Chip - a pre-burned Microchip PIC which includes code to generate PWM signals for hobby servos (2 channels) based upon an RS-232 command.
