GPIO troubles

How have you connected the LED? Did you connect the LED to GPIO P1.02 (pin # 39 on the module)? Note that the pin numbers used in the application is referring to the GPIO number (PORT_NUMBER*32 + PIN_NUMBER).

[Jørgen Holmefjord]

Which SDK version are you using? Have you tried both setting and clearing the GPIO? Have you tried setting the GPIO manually without the GPIO HAL functions?

NRF_P1->PIN_CNF[2] = (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos) |
                     (GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos) |
                     (GPIO_PIN_CNF_INPUT_Disconnect << GPIO_PIN_CNF_INPUT_Pos) |
                     (GPIO_PIN_CNF_PULL_Disabled << GPIO_PIN_CNF_PULL_Pos) |
                     (GPIO_PIN_CNF_SENSE_Disabled << GPIO_PIN_CNF_SENSE_Pos);
                              
NRF_P1->OUTSET = (1UL << 2);  // Set GPIO P1.02 high

NRF_P1->OUTCLR = (1UL << 2);  // Set GPIO P1.02 low

Mystic. I rerun Listing 2 from a colleague - everything works

[Jørgen Holmefjord]

Could there be something wrong with your module, or did you test it on the same module?

[Saram]

I tested on the same module. Firmware coincided absolutely. The only difference is that the colleague used IAR om, and I KEIL

[Jørgen Holmefjord]

Sounds like there is something wrong with your project settings then. If you post your project, I can take a look at it.

[Saram]

It no longer makes sense, changed the environment to IAR and everything works as it should (not only the GPIO, but also the entire project including SPI).
