读取芯片ID

{uint16_t chipID = BMI323_read(BMI160_REG_CHIP_ID);debug("BMI323芯片ID为0x%x;", chipID);if (chipID != 0x43){debug("未检测到BMI323;");}elsedebug("检测到陀螺仪BMI323;");u8 buf_config[2] = {0xC9, 0x70};BMI160_WriteBytes(0x21, buf_config, 2);uint16_t state = BMI323_read(0x02);debug("BMI323传感器状态为0x%x;", state);prev_yaw = agv_currentAngle.f;
}
uint16_t BMI323_read(uint8_t reg)
{uint16_t value;HAL_GPIO_WritePin(BMI160_CS_GPIO_Port, BMI160_CS_Pin, GPIO_PIN_RESET);SPI_TransferByte(reg | 0x80);value = SPI_TransferByte(0) << 8; /* 读取高8位字节 */value |= SPI_TransferByte(0);     /* 读取低8位字节 */HAL_GPIO_WritePin(BMI160_CS_GPIO_Port, BMI160_CS_Pin, GPIO_PIN_SET);return value;
}
uint8_t SPI_TransferByte(uint8_t data)
{uint8_t rxData;HAL_SPI_TransmitReceive(&hspi2, &data, &rxData, 1, HAL_MAX_DELAY);return rxData;
