Answer by Luciano Clark
I have read Programming Embedded Systems: With C and GNU Development Tools, 2nd Edition, and found it useful. It’s a good place to start. If you already have a pretty good C understanding, and you know hardware rather well you should be able to get going with it pretty easily.
You can look up the ISBN on Amazon or Half or anywhere, maybe even your local library.

Question by sum142121: Why do we need oscillators and clocks in a microcontroller?
I am starting to learn embedded programming at work , and I am having trouble understanding a clock and oscillator.
Can you help ? What does an oscillator and a clock do ?
Answer by Grant d
The oscillators cycles on and off millions of times a seconds. This is the speed of the processor. Typically every 4 oscillator cycles is a clock cycle. The processor can do one instruction in a clock cycle, some take more that one clock cycle.
Oscillators and the clock control the speed of the processor.
