NRF52832 Blinky example code problem.

I think I've found the problem. I am using our PCBA which has a QFN48 NRF52832 while the PCA10040 use QFP-100 pin IC.

My next question is how can I can change the IC to QFN48?

Thanks

Thanks for your reply. I just measured the voltage on the board. If I set bsp_board_led_on(2) it turns on OUT1 and bsp_board_led_on(3) it turns on OUT2. It seems that the command does not map to the correct I/O pins.

Here is my code:

pca10040.h

// LEDs definitions for PCA10040
#define LEDS_NUMBER 7

#define OUT1 9
#define OUT2 8
#define OUT3 7
#define OUT4 6

#define OUT_R 10
#define OUT_B 11
#define OUT_G 12

#define LEDS_ACTIVE_STATE 1

#define LEDS_INV_MASK LEDS_MASK

#define LEDS_LIST { OUT1, OUT2, OUT3, OUT4, OUT_R, OUT_B, OUT_G}

main.c

int main(void)
{
/* Configure board. */
bsp_board_init(BSP_INIT_LEDS);

/* Toggle LEDs. */
while (true)
{
for (int i = 0; i < LEDS_NUMBER; i++)
{
bsp_board_led_invert(i);
nrf_delay_ms(100);
}
}
}

Would be very helpful to show us what code changes you did and what you expect the output to be on other pins (4,5,6,7)?
