stm32f103c8t6三色RGB呼吸灯源程序

ID:581092 · 发表于 2020-6-2 08:37

这是基于stm32f103c8t6最小系统板的实验设计，供广大新手学习交流

单片机源程序如下:

#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) //简单的延时函数
{
for(; nCount != 0; nCount--);
}

没啥用呀，主要的重点如何弄一个函数接口，传参一定颜色的值，进行呼吸灯。是PWM表，指数曲线？
/* LED亮度等级 PWM表,指数曲线，此表使用工程目录下的python脚本index_wave.py生成*/
