Disable Default PCA10056 Board / Button Handling

[gos]

Hello,

I want to install my own Button & LED handling (not using the default board support). It works on the nRF52840 Dongle, but I also want it to work on the PCA10056 Board where I can debug.

*** No board support header files or c-files is included in the project. ***

On the Dongle I have configured 4 pins for Button Handling:

#define BUTTON_1 2 // P0.02 --> 0 + 2
#define BUTTON_2 47 // P1.15 --> 32 + 15
#define BUTTON_3 45 // P1.13 --> 32 + 13
#define BUTTON_4 42 // P1.10 --> 32 + 10

On the PCA10056 Board:

#define BUTTON_1 39
#define BUTTON_2 40
#define BUTTON_3 24
#define BUTTON_4 25

The following is set in sdk_config.h:

BSP_BTN_BLE_ENABLED 0

BUTTON_ENABLED 0

BLE_LBS_C_ENABLED 0

Buttons are set up as follows, using Button 1 as an example:

nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(false); // true means high accuracy
in_config.pull = NRF_GPIO_PIN_PULLUP;

err_code = nrf_drv_gpiote_in_init(BUTTON_1, &in_config, casting_power_on_pin_handler);
APP_ERROR_CHECK(err_code);
nrf_drv_gpiote_in_event_enable(BUTTON_1, true);

// I disable some buttons when they are pressed in the Event Handlers (and enable them again when others are pressed)

// Eg.g BUTTON_1 is Disabled with this code

nrf_gpio_cfg_sense_input(BUTTON_1, GPIO_PIN_CNF_PULL_Pullup, NRF_GPIO_PIN_NOSENSE);


// And later re-enabled with this code in another Button Event handler:

nrf_gpio_cfg_sense_input(BUTTON_1, GPIO_PIN_CNF_PULL_Pullup, NRF_GPIO_PIN_SENSE_LOW);

*** All this works on the Dongle, but on the PCA10056 (1.0.0 2018.35) only BUTTON_3 & BUTTON_4 works. ***

I have tried to move SW7 to the ALT positon and use the alternate Pins for BUTTON_1 (11) and BUTTON_2 (12), but that does not work either.

Can someone please help ?

Hi,

*** All this works on the Dongle, but on the PCA10056 (1.0.0 2018.35) only BUTTON_3 & BUTTON_4 works. ***

 So what behavior are you seeing with BUTTON_1 and BUTTON_2, nothing works ?

#define BUTTON_1 39
#define BUTTON_2 40

 You are testing with P1.07(39) and P1.08(40), correct ?

PS: It might be better to use the NRF_GPIO_PIN_MAP() macro for mapping port and pin numbers.

Snippet:

#define BUTTON_1       NRF_GPIO_PIN_MAP(1,7)

Hello Sigurd,

Thanks for your fast reply, and sorry for my late reply: I got caught up in tons of other stuff I also needed to take care of: I am doing a project where we are testing nRF52840 :-)

Thanks for the tip on using NRF_GPIO_PIN_MAP(1,7)!

Yes I am testing with P1.07(39) and P1.08(40).

<<So what behavior are you seeing with BUTTON_1 and BUTTON_2, nothing works ?>>

Well, nothing happens: I try to set a break point in the event handlers, but code never gets there.

What I do see though, when measuring the current, is that even though I have Pull Ups on all Button Ports , I do not see increased current when I push the Button 1 & 2: That I do see on button 3 & 4: And for Button 3, the code does stop at any break point I set in the Event Handler.

So what do you think is the problem?

Have you connect something to P1.07(39) and P1.08(40) ?

By default this switch should be in the "Def" position, and the physical "Button 1" and "Button 2" is connected to pin P0.11 and P0.12. Are these working for you?

I have solved the problem: My Bad! I had mixed up the mappings for the Default and Alt Button Mappings: Sorry!
