How to run "Nordic Thingy: 52" Demo on nrf52832 (pca10040) board?

  • Hi,

    In your image you can see that you get an error at line 209 in drv_ext_gpio.c. If you look it up you can see that it is the function called drv_sx1509_reset() that returns the error. If you dig further you can see that this function tries to reset the sx1509 by writing a few command bytes to it using TWI. So my guess is that you haven't connected an sx1509 to your PCA10040 causing the TWI write operation to fail and return an error.

  • Hi MartinBL

    Thank you

    I found the pca20020 board contains a lot of sensors, such as temperature, humidity, pressure, control quality, color, etc., but now I do not need all sensors, How do I modify the relevant function inside the Demo? Can make my pca10040 board can burn Thingy Demo
    Note: The pca10040 development board is not connected to the sensor

    Best regards,
