TAILIEUCHUNG - Programming Embedded Systems II

This course is primarily concerned with the implementation of software (and a small amount of hardware) for embedded systems constructed using more than one microcontroller. The processors examined in detail will be from the 8051 family. All programming will be in the ‘C’ language (using the Keil C51 compiler) | Programming Embedded Systems II A 10-week course using c Patterns for Time Triggered Embedded Systems Michael J.
