GB-IFD&DSP调试记录

电源管理MCU调试

配置ADC采集电流和电压，均正常，串口打印也正常。使用串口也能控制开关机。

IIC温湿度传感器读取

STM32F1系列的IIC居然没有内部上拉电阻，导致IIC读取不到，因此外部焊接了两个上拉电阻

随后成功识别到0x00和0x44，0x00为广播信号，0x44为sht30的真实地址

附IIC扫描并通关串口打印的源代码：

/**
 * @brief I2C 总线设备扫描函数 (无 printf 版本)
 * @param hi2c   I2C 句柄指针 (如 &hi2c1)
 * @param huart  UART 句柄指针，用于打印输出 (如 &huart1)
 */

{
    char msg[64]; // 临时缓冲区
    HAL_StatusTypeDef result;
    uint8_t i;
    uint8_t devices_found = 0;

    // 1. 打印表头
    const char *header = "\r\n--- Starting I2C Scan ---\r\n     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f\r\n";
    HAL_UART_Transmit(huart, (uint8_t*)header, strlen(header), 100);

    for (i = 0; i < 128; i++)
    {
        // 2. 打印行首地址 (00:, 10:, 等)
        if (i % 16 == 0)
        {
            sprintf(msg, "%02x: ", i);
            HAL_UART_Transmit(huart, (uint8_t*)msg, strlen(msg), 100);
        }

        // 3. 尝试探测设备
        // 注意：8位地址 = 7位地址 << 1
        result = HAL_I2C_IsDeviceReady(hi2c, (uint16_t)(i << 1), 3, 5);

        if (result == HAL_OK)
        {
            sprintf(msg, "%02X ", i); // 发现设备，打印 7 位十六进制地址
            devices_found++;
        }
        else
        {
            strcpy(msg, "-- "); // 未发现设备
        }

        HAL_UART_Transmit(huart, (uint8_t*)msg, strlen(msg), 100);

        }
    }

    // 5. 打印总结
    if (devices_found == 0)
    {
        const char *none = "\r\nNo I2C devices found.\r\n";
        HAL_UART_Transmit(huart, (uint8_t*)none, strlen(none), 100);
    }
    else
    {
        sprintf(msg, "\r\nScan complete. Found %d device(s).\r\n", devices_found);

SHT30读取成功，温湿度均正常，板子温度偏高
