STM32F03C8T6+ADC信号采集+OLED波形显示
✨本项目来源于开源项目，可以自行准备一块STM32F03C8T6和一块OLED屏幕就可以验证并演示出效果。🔖通过手指皮肤接触探测输入引脚：
PA7🌿PA8引脚上的方波输出
🌿PB13引脚上的方波输出
PB13和PA8:互补型方波输出引脚
🛠硬件搭建
🌾OLED屏幕：可以是0.96寸屏幕或者是1.3寸 IIC接口的OLED屏幕🌴STM32F103C8T6最新系统板一块🌿若干导线🍁工程架构
📝接线说明
ADC检测引脚：PA7，相关定义在BSP_ADC.hOLED IIC引脚定义：bsp_i2c_gpio.hSDA --- PA3SCL --- PA2PWM方波输出引脚：BSP_ADVANCED_TIMER.hPB13和PA8:互补型方波输出引脚，PB12:低电平
⛳0.96寸屏幕和1.3寸屏幕驱动细节差异说明
清屏函数在
OLED_I2C.c文件中
void OLED_CLS(void)//清屏{uint8_t i,j;for(i=0;i<8;i++){WriteCmd(0xb0+i);//page0-page8WriteCmd(0x02);//low column start address1.3寸屏幕发送地址是从0x02开始的，0.96屏幕是从0x00地址开始的特别注意个地方！！！！WriteCmd(0x10);//high column start addressfor(j=0;j<128;j++){DataBuffer[i][j]=0x00;}}Write_DataBuffer();}
初始化函数
