RY-Teach STC12C5A60S2 Mac环境搭建

# stc12c5a60s2 # mac # 51单片机 # 开发环境

1.编辑器

brew cask install visual-studio-code

2.开发平台

3.开发包

4.开发包无 STC12C5A60S2 自定义 board

  "name": "Generic STC12C5A60S2",
  "url": "https://www.stcmicro.com/stc/stc12c5a32s2.html",
  "vendor": "STC"
}

将 json 放入 Users/{YourName}/.platformio/platforms/intel_mcs51/boards 命名为 stc12c5a60s2.json

5.创建项目

首先重启 Vscode，使得 platformIO 重新读取 boards 里的配置文件

6.编写项目

src 下新建 led.c

#include <stc12.h>

#define R P0_2
#define G P0_1
#define B P0_0

void delay_ms(unsigned int s)
{

    unsigned int x;

    for (s; s > 0; s--)
    {
        x = 98;
        while (x--)
            ;
    }
}

void main()
{
    while (1)
    { //主循环

        R = 0xff;
        G = 0xff;
        B = 0xff;

        delay_ms(150);

        for (int i = 0; i < 8; i++)
        {
            R = R << 1;
            G = G << 1;
            B = B << 1;
            delay_ms(150);
        }

        R = 0xff;

        delay_ms(150);

        for (int i = 0; i < 8; i++)
        {
            R = R >> 1;
            G = G >> 1;
            B = B >> 1;
            delay_ms(150);
        }
    }
}
