Nordic Thingy91 GPIOs

[Alejandro Chavez]

Hi everyone!

Have the Thingy:91 GPIOs ports available to use it in order to control relays, LEDs, buzzers, etc. ?

Regards.

Hi Alejandro,

Please refer to the Thingy:91 documentation.

You can see that it already have LEDs and a Buzzer on-board:

However if you want connect something else over some GPIOs there are some that are externally available.
Check pin maps for more information

Thanks Martin,

I have checked out and those GPIOs (external available) belongs to the nRF52840,my question is:

Can I use it when i'm in nRF9160 switch mode.

Hi Alejandro,

What do you mean by nRF9160 switch mode?

The nrf52840 works as a board controller on the board, so the nrf9160 communicates with the nrf52 and can therefore get the information from those GPIOs routed out of the nrf52.

(If you refer to the physical switch on the PCB that is only for routing either to nrf52 or nrf91 with regards to flash/debug)

best regards,

Sorry! I was a bit confused about the physical switch on the PCB.

I want to recycle the Asset Tracker application that it's currently running but including one function that sets one of GPIOs as 1 (logically True) or 0 (logically False) when the device receives in an specific topic a message like {"lights":"on"}.

How can I set as 1 or 0 an specific GPIO from the main.c?
