Pull up P0.08

[xuezhi_zed]

Hi, 

I am trying to pull up P0.08 as an enable pin for this switch TPS7A0518 

I use the following code and verified on development board 

gpio_pin_configure(gpio0_dev, GPIO_0_TPS_EN, GPIO_OUTPUT);
gpio_pin_set(gpio0_dev, GPIO_0_TPS_EN, 1);

However, when I move to customized board, it does not work. I am providing a 1.8V source to VCC_NRF 

Anything else I should check or correct? 

Thank you

Hello,

I'd recommend you to have a look at the documentation here:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/config_and_build/hardware/use_gpio_pin_directly.html

You should aslo be able to check the GPIO names with the correct absolute pin number, you can use the NRF_GPIO_PIN_MAP helper macro in nrf_gpio.h.

Best regards

Asbjørn

Hello,

Do you have some old project that you are working with since you are using NCS 2.5.2?

Did you make any changes to the project to reflect your custom board?

Is the build working now or do you see other issues with the parts you've commented out?

Best regards

Asbjørn

Hi , Sorry for the late reply, was having a break for chinese new year 

I think i did not make myself clear , I comment out this 

&gpiote0 { status = "okay"; };

and did not change the rest 

and the board now works 

1. yes,i have been using 2.5.2 for a long time
