hi,
after some time i think its time to learn arm programming, i used to program for avr, (im mainly a pc programmer ! young one )
i got an Raspberry pi model b+. but i don't want to use it for making fun stuff or hobby, i want to do real programming(not that python and pi are not real programming i can't explain what i mean) , so i can work somewhere(i don't want to but example of what i mean, im not looking to make stuff, im looking to learn!!!) or make products! (like nest self learning thermostat or the Parrot ar.drone)
raspberry pi has an os and its a big boards and has unneeded stuff so i don't want to use it on my final product (release it with a pi inside of it!)
like in avr i wrote my c program for my chip on breadboard, or an arduino, after that i just installed the final version into a chip ans inserted it into a final cricut , but not the whole arduino! (like lets say i made an automatic cat feeder and released it for public!!! )
i want to do the same, so my question is:
how can i start it? Do i need to know Assembly? i only know a little bit of PC assembly, it sounds cool
i heard different MPU/MCU's require learning the whole thing again, i may use different stuff on different projects, that means i have to learn it again for each project?!
lets say my goal is to make AR.Drone from scratch, by buying motors the chips and ect, but i want to prototype it with pi first, and the OS and other stuff just require battery and waste resources , how can i do it?!
so what should i do/learn to make an AR.Drone?! (i know its not like i wake up and decide to build a time travel machine but i will learn what's necessary because i have time and im looking to learn !)
sorry if this question sounds stupid but i have been really confused these days so i thought its good to make a thread!
EDIT:
let me summirize it a little !
Summary:
im moving from AVR programming to ARM,
what steps i should take? what should i learn?
i want to use ARM for making products and devices , i already bought an pi to prototype before i can make it a product , in its own board with other stuff in the board
a good example of what i want is ar.drone !
my main problem with Pi is that the software i make for it is only for the Pi board, i want to be able to create a board with my desired components ! i feel like the pi is more of a computer ! i want to use ARM as components like MCU(when AVR mcu's don't have enough power! and doesn't meet my needs) , maybe in my project i dont even need video at all!!
like with AVR, or even arduino, i could flash arduino bootleder on many of AVR MCU's and make my programm run on it and forget about the board and insert my AVR MCU on a cricut !
if that needs me to learn asm i will do that ! but if there's easier way i would gladly do that i just hate the fact that i have to learn the whole thing again for other ARM Contexes !
sorry i can't explain good
and also i saw that ar.drone uses linux !
im so confused just forget about first one and answer this using Linux sounds like a lot of help, and it seems like i can install Linux on any Cortex, and the programs only work on pi, i want to be able to create my cost effective boards with different Cortex rather than Pi's current one or maybe more powerful ones ! ( i see there are many different Cortexes !)
pi looks like more of an mini computer to me now !
What do you not use an existing board without display output ?
like the Arduino Due based on ARM cortex M3 for exemple in your case.
I don't know exactly what you project, but it could be suffisant ?
thats an example, but still lets say i work for an company, big one like parrot they just can't use an arduino on they're ar.drone or anything, also these boards are big, i mostly want to learn, i don't have specific projects, i want to learn the skill of programming arm MPU's for different devices or stuff!
