{

    // Configure Configuration Register A
    config_reg_a[0] = 0x00; // CH7-CH0 = 00000000 (default)
    config_reg_a[1] = 0x00; // REFON = 1, ADCOPT = 1, GPIO1-5 = 1 (default)
    config_reg_a[2] = 0x00; // DUMMY BYTE (default)

    // Configure Configuration Register B
    config_reg_b[0] = 0x00; // CELL10-5 = 00000000 (default)
    // CHGUP = 1, CHGDIS = 1 (disable charging), CELL4-0 = 00000000 (default)

    spi_init();

    // Write the configuration register group
    ltc6806_write_config_reg(config_reg_a, config_reg_b);

    while (1) {
        // Main loop
    }
}

其中，`spi_init()`函数用于初始化STM32的SPI接口，`ltc6806_write_config_reg()`函数用于构建并发送写配置寄存器组的SPI数据帧，`main()`函数中调用了`ltc6806_write_config_reg()`函数。具体的LTC6806寄存器配置可以根据实际需求进行修改。
