CoIDE je veoma nestabilan, guta resurse, pada, a i u trenutku kada je radio, imao sam konfliktre tokom kompajla, nesto ne radi lepo sa repozitorijumom...
Attolic generalno nije los, a primetio sam da nema release konfiguraciju, samo debug.
A primetio sam razliku u elementima strukture GPIO_TypeDef, jer sadrzi short elemente BSRRL i BSRRH, dok je u drugim okruzenjima int BSRR (nije strasno, ali moze napraviti zbrku tokom migracije na neko drugo okruzenje)
U oba slucaja nisam uspeo da nateram lampice da blinkaju...
Ploca na kojoj radim je bazirana na ovom uC
http://www.mikroe.com/mini/stm32/
Na ploci ne postoji taster, i samo je jedna lampica na A14 portu.
Sad primeri kodova:
Keil:
Code (c):
void delay(int value) {
int i = value*10000;
while(i>0) {i--;}
}
void blinky (void const *argumnt) {
while( 1 ) {
GPIOC->BSRR = GPIO_BSRR_BS_13;
GPIOC->BSRR = GPIO_BSRR_BS_12;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BR_13;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BR_12;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BS_13;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BS_12;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BR_13;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BS_13;
delay(500);
GPIOC->BSRR = GPIO_BSRR_BR_13;
GPIOC->BSRR = GPIO_BSRR_BR_12;
delay(500);
// */
// /* lampica koja se ne pali
GPIOA->BSRR = GPIO_BSRR_BS_14;
delay(500);
//osDelay(200);
GPIOA->BSRR = GPIO_BSRR_BR_14;
delay(500);
//osDelay(500);
GPIOA->BSRR = GPIO_BSRR_BS_14;
delay(500);
//osDelay(200);
GPIOA->BSRR = GPIO_BSRR_BR_14;
delay(500);
// */
}
}
/*
* main: initialize and start the system
*/
int main (void) {
// initialize peripherals here
RCC->AHB1ENR = (RCC_AHB1ENR_GPIOCEN | RCC_AHB1ENR_GPIOAEN);
// RCC->AHB1ENR |= (RCC_AHB1ENR_GPIOAEN);
// /* // inicijalizacija C12 i C13
GPIOC->MODER |= (GPIO_MODER_MODER12_0 | GPIO_MODER_MODER13_0);
GPIOC->OTYPER &= ~(GPIO_OTYPER_OT_12 | GPIO_OTYPER_OT_13);
GPIOC->OSPEEDR |= (GPIO_OSPEEDER_OSPEEDR12 | GPIO_OSPEEDER_OSPEEDR13);
GPIOC->PUPDR &= ~(GPIO_PUPDR_PUPDR12 | GPIO_PUPDR_PUPDR13);
// */ // inicijalizacija A14
GPIOA->MODER |= (GPIO_MODER_MODER14_0 );
GPIOA->OTYPER &= ~(GPIO_OTYPER_OT_14);
GPIOA->OSPEEDR |= (GPIO_OSPEEDER_OSPEEDR14 );
GPIOA->PUPDR &= ~(GPIO_PUPDR_PUPDR14 );
blinky(0);
}
Ovaj kod pali samo C12 i C13 LED, a ne i A14. Da li neko primecuje, da li sam izostavio nesto tokom inicijalizacije?

main sam modifikovao, jer je originalni primer pravljen za diskovery plocu, koja ima i taster, ali svakako ne pali lampice.
i zna li neko cemu sluzi toggle u ovom primeru?
