Blinky example in SDK17 is not working on a NRF52832 chip

[Masoumeh]

Hi,

I am using nRF52832 on a PCB that is designed by me. I tried to toggle one LED on my board, it is connected to the P10 of nRF52832. I changed the LED number in pca10040.h . I am programming the nrf52832 through J-link, I know that the nRF is working since the counter (i) in the example is changing ( I checked it by start/stop debug session option in Keil). but the problem is that the LED didn't toggle. I also tryed to set one of the gpios, but it didn't work. the nRF that I am using is nRF52832 QFN48. isn't this library compatible with this 48 pin IC?

please help. 

thanks

Hi,

Pin 9 and 10 can be used as NFC:

Have you set CONFIG_NFCT_PINS_AS_GPIOS in the preprocessor to make sure these pins can be used as GPIOs? See system_nrf52.c handling of CONFIG_NFCT_PINS_AS_GPIOS.

Best regards,
Kenneth

Thanks , I will check on that. but what about pin 27? I tried to set and reset this pin too, but it didn't work.

Have you tried to include nrf_gpio.h and call:

nrf_gpio_cfg_output(your_pin);
nrf_gpio_pin_toggle(your_pin);

I understood that the problem is that the pin that is connected to a PMOS's Gate, which is a switch in our design, doesn't work properly. do you have any idea?
