button exmaple is not working in SDK version 9.0.0

[MARTIN FR]

Hello evryone,

i cloned button example form github to sdk version 9.0.0 and i modified the neccesary changes between app.gpiote.c//nrf_drv_gpiote.c files and set the GPIOTE ENABLED to 0 after that it is getting compiled with no errors but the baord shows nothing if the press any of the button can anyone suggest me what modifications has to be done or any changes?

Hi prabhudurai,

still havent gone through your code, but had a quick look. I saw this below code in your init_gpio() function

NRF_GPIO->PIN_CNF[6] = (GPIO_PIN_CNF_DRIVE_H0D1 << GPIO_PIN_CNF_DRIVE_Pos);

This is wrong as you are setting every other bits to '0' and only setting the drive strength. With this the pin will be configured as input. To do this correctly, you need to do this below

NRF_GPIO->PIN_CNF[6] &= ~(GPIO_PIN_CNF_DRIVE_Msk); // reset drive setting
NRF_GPIO->PIN_CNF[6] |= (GPIO_PIN_CNF_DRIVE_H0D1 << GPIO_PIN_CNF_DRIVE_Pos); // set to high drive

you need to do this for pin settings 7 also.

i have tested the the buzzer by configuring channel 0 pin 6 and channel 1 pin7 but the pin 6 continously receiving 2.9v at the same time the pin 7 is shpwing only 1.5v whenever the buzzer is making beep rest of the time pin 7 showing only 0v can you please clarify this issue?

app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_2CH(160UL,7,6);//6.3KHz

pwm1_cfg.pin_polarity[1] = APP_PWM_POLARITY_ACTIVE_LOW;
