Hi gregers,

Take a look at this post. It covers routing UART pins, but the same method is used for the LEDs and buttons. The board controller can be found here. (it's included when you build e.g. hello_world sample for target nrf52840_pca10090, and configurable with kconfig/menuconfig)

The nRF9160 DK User Guide v0.7.2 states: «Configurable code examples for the nRF52840 allowing to change the board routing can be found in the nRF Connect SDK».

I've looked in the applications and samples folder, but I can't find it. Is it still not available? Is there a trace on the PCB I can cut to use P0.02-P0.09 from the pin headers?

Dear Sigurd,

For example: the LED1234 control

the info from the backside of nrf9160 DK pcb

GPIO	Function
P0.02	LED 1
P0.03	LED 2
P0.04	LED 3
P0.05	LED 4
P0.06	Button 1
P0.07	Button 2
P0.08	Button 3
P0.09	Button 4
P0.26	CTS
P0.27	RTS
P0.28	RxD
P0.29	TxD

On the schematic, Switches are used for selection

example: pin P0.02 (from nRF91) will select LED1 or D2 (P0.02 on the PCB-P14), and the control pin nRF52_P1.05 (from nRF52)

So, we need one program for nRF52 to control for GPIO:

nRF9160_DK_board_controller_FW.hex

Currently, the pin P0.02 will connect LED1 so pin D2 (P0.02 on the PCB-P14) is floating

Do we have any option ( for example : CONFIG_GPIO=y in prj.conf ) to enable pin D2 (P0.02 on the PCB-P14) ?

then I can use it as normal gpio

regards,

thanks

hng

Hi,

The board controller fw is currently not available in source code. But as mentioned at this link, it's possible to route some pins differently from what is done in the preprogrammed firmware.
