Sure! Here's an example of a simple LED blinking code for STM32 microcontrollers using the Standard Peripheral Library (SPL):
```c
#include "stm32f10x.h"
void Delay(uint32_t nTime);
int main(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
// Enable GPIOC clock
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
// Configure PC13 as output push-pull
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_Init(GPIOC, &GPIO_InitStructure);
while (1)
{
// Toggle the LED state
GPIOC->ODR ^= GPIO_Pin_13;
// Delay for a while
Delay(1000000);
}
}
void Delay(uint32_t nTime)
{
for (; nTime != 0; nTime--)
{
}
}
```
This code configures pin PC13 as an output and toggles its state to make the LED blink. The `Delay` function creates a software delay by simply counting down a variable.
Note: This code uses the Standard Peripheral Library (SPL) which is deprecated for newer STM32 microcontrollers. For newer devices, it is recommended to use the Hardware Abstraction Layer (HAL) or the Low-Level (LL) libraries provided by STMicroelectronics.
Let me know if you have any further questions!
