精密双向电流感应放大器设计方案 【有奖直播】提升毫米波信号测试精度

MM32使用模块

1. 串口使用C0 C1 口配置LPUART

2. ADC 使用板子上连了滑动变阻器的A1、A4、A5测试

3. IRM使用A9、A10

4. LCD模块

5. LED 使用三个灯 GPIOB9 GPIOB10 GPIOB11

6. RTC模块测试验证时间显示

配置串口上

RCC_APB2PeriphClockCmd(RCC_APB2ENR_LPUART1, ENABLE);
    LPUART_StructInit(&LPUART_InitStructure);    LPUART_InitStructure.LPUART_BaudRate        = LPUART_Baudrate_9600;    LPUART_InitStructure.LPUART_WordLength      = LPUART_WordLength_8b;    LPUART_InitStructure.LPUART_StopBits        = LPUART_StopBits_1;    LPUART_InitStructure.LPUART_Parity          = LPUART_Parity_No;    LPUART_InitStructure.LPUART_Clock_Source    = 0;    /* 0:LSE   1:LSI   2:PCLK */    LPUART_InitStructure.LPUART_MDU_Value       = 0x952;    LPUART_InitStructure.LPUART_NEDET_Source    = LPUART_NegativeDectect_Source1;    LPUART_InitStructure.LPUART_RecvEventCfg    = LPUART_RecvEvent_OneByte_Complete;    LPUART_Init(LPUART1, &LPUART_InitStructure);
    LPUART_ITConfig(LPUART1, LPUART_LPUCON_RXIE, ENABLE);
    LPUART_Cmd(LPUART1, ENABLE);
    RCC_AHBPeriphClockCmd(RCC_AHBENR_GPIOC, ENABLE);
    GPIO_PinAFConfig(GPIOC, GPIO_PinSource0, GPIO_AF_2);    GPIO_PinAFConfig(GPIOC, GPIO_PinSource1, GPIO_AF_2);

引脚复用参考如下：

Adc使用三个连接滑动变阻器的口如下：

代码配置如下：

ADC_StructInit(&ADC_InitStructure);    ADC_InitStructure.ADC_Resolution         = ADC_Resolution_12b;    ADC_InitStructure.ADC_PRESCARE           = ADC_PCLK2_PRESCARE_16;    ADC_InitStructure.ADC_Mode               = ADC_Mode_Continue;    ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;    ADC_InitStructure.ADC_ExternalTrigConv   = ADC1_ExternalTrigConv_T3_CC3;    ADC_InitStructure.ADC_DataAlign          = ADC_DataAlign_Right;    ADC_Init(ADC1, &ADC_InitStructure);
    ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 0, ADC_Samctl_240_5);    ADC_RegularChannelConfig(ADC1, ADC_Channel_4, 1, ADC_Samctl_240_5);    ADC_RegularChannelConfig(ADC1, ADC_Channel_5, 2, ADC_Samctl_240_5);

IRM模块配置：

引脚复用情况：

GPIO_PinAFConfig(GPIOA, GPIO_PinSource9,  GPIO_AF_7); // IR outGPIO_PinAFConfig(GPIOA, GPIO_PinSource10, GPIO_AF_1); // UART1_RX

服用配置后使用A9口发送，A10口作为接收

使用UART1寄存器值作为发送数据值

static uint8_t IRM_Count = 0x01;if (IRM_Count < 0xFF) IRM_Count ++;else {        IRM_Count = 0x01;
    }// printf("\r\n IRM Send data : 0x%x\n", IRM_Count);    UART_SendData(UART1, IRM_Count);while(UART_GetFlagStatus(UART1, UART_FLAG_TXEPT) == RESET);

使用UART1中断接收

void UART1_IRQHandler(void){uint32_t ValueRec = 0;
if(UART_GetITStatus(UART1, UART_IT_RXIEN) != RESET)    {        ValueRec = UART_ReceiveData(UART1);printf("\r\n IRM_RecvHandler Recv Data : 0x%x\n", ValueRec);        UART_ClearITPendingBit(UART1,  UART_IT_RXIEN);
        LCD_DisplayNumber2(4, '0' + (ValueRec / 10), 0);        LCD_DisplayNumber2(5, '0' + (ValueRec % 10), 0);    }}
