RE: Programowanie ARM, nauka, środowiska programistyczne IDE
IMHO EmBitz moze byc jednym ze srodowisk, ale wtedy pomijamy poczatkujacych pracujacych na Linux... a widac ze jest 14 osob. Mnie z OS X w ankiecie mozna pominac (jestem w stanie odpalic sobie dowolne srodowisko).

Jednak trzeba przemyslec by bylo to wszystko kompatybilne ze soba i robic projekty tak aby nie byc ograniczonym do danego srodowiska.

Przykladowo automatyczne zalozenie projektu w Eclipse dla STM32F4 wyglada tak:

İmage

na ile to jest kompatybilne z innymi... to hmmm

w main wygenerowany z automatu przyklad blinkled:

// Standalone STM32F4 led blink sample (trace via DEBUG).

// Trace support is enabled by adding the TRACE macro definition.
// By default the trace messages are forwarded to the DEBUG output,
// but can be rerouted to any device or completely suppressed, by

i tak na to patrze i hmm ja bym to wypierniczyl Wink na sile dowala HAL i inne bzdury robiac z prostego projektu cos co raczej poczatkujacemu trudno wytlumaczyc...
do tego zwiazani jestesmy z srodowiskiem co czasem mocno utrudnia dodanie jakis gotowych blokow RTOS-y, FAT, stosy TCP/IP itd.
Ja jestem bardziej za podejsciem ze IDE pomaga, ale nie jest podstawa przy tworzeniu projektu. Z takim podejsciem to mozna stworzyc/przekompilowac/zaprogramowac uklad majac dostep tylko do konsoli z gcc,vi, openocd/jlink Smile
