NRF52832 S132 MPU6050 TWI
I want to finish the function:
- When the ACC, GYRO data update, the INT pin to generate an interrupt, and then in the P026 pin configuration falling edge trigger GPIOTE interrupt,and then read the ACC, GYRO data in the interrupt function.
I have now verified the following results:
1.Finished this function by pressing the S1 button, i can read the ACC data through GPIOTE
2.The ACC data is changed by the ACC data printed by the UART.If the MPU6050 interrupt configuration is successful, it should be in the INT to generate an interrupt signal.
Problem； When the ACC data is updated and successfully written to its corresponding register, why is there no interrupt on the INT pin?
The code is as follows:
bool mpu6050_init(uint8_t device_address)
{
bool transfer_succeeded = true;
uint8_t res;
m_device_address = (uint8_t)(device_address << 1);
mpu6050_register_write(MPU_PWR_MGMT1_REG , 0x80);
//#define MPU_PWR_MGMT1_REG 0X6B
nrf_delay_ms(1000);
mpu6050_register_write(MPU_PWR_MGMT1_REG,0x01);
mpu6050_register_write(MPU_GYRO_CFG_REG , 0x18);
//#define MPU_GYRO_CFG_REG 0X1B
mpu6050_register_write(MPU_ACCEL_CFG_REG,0x00);
//#define MPU_ACCEL_CFG_REG 0X1C
mpu6050_register_write(MPU_SAMPLE_RATE_REG , 0x04);
//#define MPU_SAMPLE_RATE_REG 0X19
mpu6050_register_write(MPU_CFG_REG , 0x03); //MPU_CFG_REG 0x1A
mpu6050_register_write(MPU_INT_EN_REG,MPU_DATA_RDY_EN_INT);
//#define MPU_INT_EN_REG 0X38
//#define MPU_DATA_RDY_EN_INT 0X01
mpu6050_register_write(MPU_USER_CTRL_REG,0X00);
//#define MPU_USER_CTRL_REG 0X6A
mpu6050_register_write(MPU_INTBP_CFG_REG,0X30);
//#define MPU_INTBP_CFG_REG 0X37
return transfer_succeeded;
}
