How can I see some hidden log on Thingy:52 debug?

[manumonti]

Hi all,

I'm working with 2.1.0 version of Thingy:52 firmware (the last version currently). Further I am working on Linux with SEGGER J-Link Commander V6.34c in order to debugging and programming Thingy:52. For this, I'm using nRF52840 DK connected to Thingy:52 by Debug Out port.

Currently I'm working on Thingy:52 accelerometer, so I want to see logs from accelerometer driver or lis3dh chip. Of course, I have set NRF_LOG_ENABLE to 1 on sdk_config.h, and I see others log messages, but none about accelerometer.

This is the log I can see:

Any ideas?

Thank you in advance,

Hi Manuel,

Add this in sdk_config.h.

#define NRF_LOG_ENABLED 1

#define NRF_LOG_DEFAULT_LEVEL 4

Increase the NRF_LOG_DEFAULT_LEVEL to 4 to get out debug messages as you can see in "drv_motion.c":

#if NRF_LOG_ENABLED
    void print_sensor_status(void)
    {
        long acc_bias[NUM_AXES];
        long gyr_bias[NUM_AXES];
        long mag_bias[NUM_AXES];
        int acc_accuracy;
        int gyr_accuracy;
        int mag_accuracy;
        
        inv_get_accel_bias(acc_bias, NULL);
        inv_get_gyro_bias(gyr_bias, NULL);
        inv_get_compass_bias(mag_bias);
        
        acc_accuracy = inv_get_accel_accuracy();
        gyr_accuracy = inv_get_gyro_accuracy();
        mag_accuracy = inv_get_mag_accuracy();
        
        NRF_LOG_DEBUG("Acc bias: ");
        NRF_LOG_DEBUG("X: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(acc_bias[0]));
        NRF_LOG_DEBUG("Y: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(acc_bias[1]));
        NRF_LOG_DEBUG("Z: "NRF_LOG_FLOAT_MARKER" \r\n", NRF_LOG_FLOAT(acc_bias[2]));
        
        NRF_LOG_DEBUG("Gyr bias: "); 
        NRF_LOG_DEBUG("X: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(gyr_bias[0]));
        NRF_LOG_DEBUG("Y: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(gyr_bias[1]));
        NRF_LOG_DEBUG("Z: "NRF_LOG_FLOAT_MARKER" \r\n", NRF_LOG_FLOAT(gyr_bias[2]));

        NRF_LOG_DEBUG("Mag bias: ");
        NRF_LOG_DEBUG("X: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(mag_bias[0]/(2^16)));
        NRF_LOG_DEBUG("Y: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(mag_bias[1]/(2^16)));
        NRF_LOG_DEBUG("Z: "NRF_LOG_FLOAT_MARKER" \r\n", NRF_LOG_FLOAT(mag_bias[2]/(2^16)));

        NRF_LOG_DEBUG("Accur: Acc: %d, gyr: %d, mag: %d \r\n", acc_accuracy, gyr_accuracy, mag_accuracy);
    }
#endif
