FILE ARM PROGRAMMING “It seems that perfection is attained not when there is nothing more to add,
but when there is nothing more to remove.” (Antoine de Saint-Exupery)
Write your ARM programs in an easy, clear native manner.
Reduce your development time to a minimum.
ARM SoC is considered as a simple microcontroller but with 32-bit, MIPS, Megabytes of RAM and Gigabytes of external storage memory!

ARM PROGRAMMING
Task A executes and starts to write the string “Hello world” to the LCD. Task A is pre-empted by Task B after outputting just the beginning of the string – “Hello w”. Task B writes “Abort, Retry, Fail?” to the LCD before entering the Blocked state. Task A continues from the point at which it was preempted and completes outputting the remaining characters – “orld”. The LCD will now be displaying the corrupted string “Hello wAbort, Retry, Fail?orld”.

Low-Level C ProgrammingIn its role as a high level assembler used for writing operating systems, C is often used to access memory locations and change individual bits. You might for example need to access individual bits in an int. It can sometimes be useful to conserve memory by using a byte to hold 8 flags though with an abundance of ram it's common to just use one byte per flag or even one per int. Knowing how to extract or alter individual bits is still worthwhile knowing; you may never have to use it but when you have to maintain code that...
