stm32f103c8t6三色RGB呼吸燈源程序

這是基于stm32f103c8t6最小系統(tǒng)板的實驗設(shè)計，供廣大新手學習交流

單片機源程序如下:

#include "breathing_led.h"
#define SOFT_DELAY() Delay(0xFFFFFF);
__IO uint32_t rgb_color = 0x9CE326; // 156 227 38
int main()
{
Breath_LED_Init();
while(1)
{
}
}
void Delay(__IO uint32_t nCount) //簡單的延時函數(shù)
{
for(; nCount != 0; nCount--);
}

沒啥用呀，主要的重點如何弄一個函數(shù)接口，傳參一定顏色的值，進行呼吸燈。是PWM表，指數(shù)曲線？
