I am interesting in learning about ARM Cortex microcontrollers. I know how to use 8-bits atmel microcontrollers and i learned how to use the 8-bits micros reading books
i see in internet that ARM Cortex are a little more complex to learn to program and use , so i thought that the best form to learn how to program this microcontrollers was with these books(in that orden):
also i have bought this book: ( Atmel ARM Cortex ) that looks pretty more practical and the SAMD21 xplained pro board (both will arrive in some weeks, cuz i bought by internet)
My questions are:
-consider you that reading those books is a good form of learn to use the microcontrollers?
-Have anybody use or buy those books?
-(i want to learn to use Cortex M0+ & Cortex M4) should you change those books for others?
-Consider you that program and use ARM Cortex architectures are hard to learn?
other advice that you can give me to achieve this task would be really welcome
