Ankieta: Jaki system operacyjnym preferujesz

SP6VGX · 06-07-2016 12:43

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:

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

w main wygenerowany z automatu przyklad blinkled:

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

//

// In debug configurations, demonstrate how to print a greeting message

// on the trace device. In release configurations the message is

// simply discarded.

// Then demonstrates how to blink a led with 1 Hz, using a

// continuous loop and SysTick delays.

//

// 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

// changing the definitions required in system/src/diag/trace_impl.c

// (currently OS_USE_TRACE_ITM, OS_USE_TRACE_SEMIHOSTING_DEBUG/_STDOUT).

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
