Thanks Erik for the pointer. There was a race issue in initializing the pin before the driver was ready. I changed from SYS_INIT(board_init, POST_KERNEL, CONFIG_KERNEL_INIT_PRIORITY_DEFAULT); to SYS_I

I realize I mentioned the need to set the pin low and that code above is attempting to set the pin high. If I just start the board without this code, the pin is measured low on my oscilloscope even wi

Greetings, I'm working on adding a board to Zephyr. I'm attempting to use a board.c file to configure GPIO pins as output and initialize them low on start-up. I've attempted to follow existing boards,

Hello, Can someone please tell how to read/write to GPIO pins (ports P0 and P1)? I am using zephyr and NRF Connect v1.30 Thank you. Kind regards Mohamed Belaroussi

Ok, found the issue: It was do to pin mapping naming. I was assuming that the pinmaps in Arduino D5, D6, and so on, corresponded to a direct GPIO map, so D5->GPIO_5 and so on... and that's not true. A

#gpio #nrf52832

Have you done the initialization by running gpio_pin_configure with GPIO_OUTPUT_ACTIVE as third argument ? Just to be clear, you´re trying to set pin p0.05 ? That´s located on chip pin7 (QFN48 pkg) ?

Hi, No MCUBoot. And yes, the board boots correctly and I can use GDB to debug. I can see the GPIO driver calls, the values that are set and so on. My prj.conf file is as simple as it can get: CONFIG_G

Are you sure that your board boots correctly? ( debug through gdb or just simple serial output ) What version of the SDK are you using? Is MCUBoot activated in your prj.conf?

Not sure if I'm going to have any help on this, but anyway: I've a standard NRF52832 module that has connected to pin 5 a red LED. If I flash the module (through JLink) with the Arduino framework, the

Hi Brian: You can always test the value of the GPIO with gpio_pin_read() in the callback, if it is 1, then the cause is a rising edge, and if it is 0 the cause was a falling edge. Unfortunately if the
