Problem!!! i got problem on gpio pin in nRF52810.

[Urvisha Andani]

Hello All,

I am working on nRF52810 development board. I use segger studio in windows 7. for reference i use nRF52 15.2.0 SDK. Right now I am trying to do blinking led which is connect with pin no p0.06.

i define p0.06 pin as output. and i do p0.06 pin set and reset by progrmaing. And also by default pin is high.My problem is pin p0.06 is not working. means pin p0.06 status is always high. if reset the pin p0.06 but status of pin p0.06 is not changes means output is always high if i reset the pin p0.06. I also trying this in BT832A at same pin in which nRF52810 is use. But same problem create. And all other gpio pin is working properly. 

please solve my problem as soon as possible.

Thanks & regards,

Urvisha Andani

Hi Urvisha

What example project are you using? I am guessing the project you are using have P0.06 assigned to another task, which causes it to stay high.

Hi Simanr,

in ble_template example.

nRF5_SDK_15.2.0_9412b96_1->examples->ble_peripheral->ble_app_template->pca10040e->s112->ses

in this i add this

nrf_gpio_cfg_output(6);

while(1)

{

nrf_gpio_pin_clear(6);

nrf_delay_ms(1000);

nrf_gpio_pin_set(6);

nrf_delay_ms(1000);

}

and then upload program.

Can it be that you have uart enabled (or log with uart enabled)? Since P0.06 is used by UART TXD by default.

HI,

I am not use evolution board or development board. I used custom board and extremely sorry for give wrong information.

even so, if you are using a Nordic example, it may assume that P0.06 is used by UART TXD ... ?
