1简介 数显交流电压表芯片采用ST公司低成本、高性价的STM8S003F3，并固化数显表采样算法，显示程序而成。STM8S003F3直接采样交流电压信号，并进行数字滤波器，有效值算法算出电压有效值，刷新速度快。采用本芯片的数显电压表方案具备成本低，外围电路简单，体积小，生产方便。芯片自带校准功能，校准方便，校准速度快等...
STM8S-DISCOVERY-STM8S003K3原理图
stm8s003电流检测控制板(包括原理图、PCB和程序)通过MAX471检测1A输入电流, STM8S003F3P6 引脚图和功能引脚 NRST (I/O):复位引脚 PA1/OSCIN(2) (I/O):端口 A1 引脚 PA2/OSCOUT (I/O):端口 A2 引脚 VSS(S): 1、注意芯片的两个IIC引脚都是开漏输入,所以需要外接上拉电阻。这就是为什么很多人只读00...
再如用UART0中断收发,使用的是CX32L003 的PA1(UART0_RX) 和PA2(UART0_TX) : 复制 static void uart0Config(void)//串口初始化 { //USART0 #if 0 ///RCC_UART0_CLK_ENABLE; RCC_UART0_GPIO_ENABLE; /* //PA1 - UART0 RX,PA2 - UART0 TX GPIOA->AFR &= 0XFFFFF00F;// GPIOA->...
