Posted on June 22, 2017 at 02:37Hello, I'm a new with STM32.
I have Nucloe-N053R8, Win8.1, SystemWorkbench.
I made a short program and it seems that I could send the program to the Nucloe-board, but it doesn't work. I can see the console said 'target halted due to breakpoint'. But there is no breakpoint.
Nucleo-board have LED as LD2, connected PA5. My program wants to blink it. I just did click the 'RUN' button on the Systemworkbench.
I have no idea whether my program is incorrect or if the operation of Workbench is incorrect.
---my program----
#include 'stm32l0xx.h'
#include 'stm32l0xx_nucleo.h'
#include 'stm32l0xx_hal_gpio.h'
int main(void)
{
HAL_Init();
GPIO_InitTypeDef pin_PA5;
pin_PA5.Mode = GPIO_MODE_OUTPUT_PP;
pin_PA5.Pin = GPIO_PIN_5;
HAL_GPIO_Init(GPIOA, &pin_PA5);
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_SET);
for(;;){
double i=0;
while(1){
i = i +1;
if(i>100000){
break;
}
}
HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_5);
}
}
---the console result---
