1.问题描述

when compiling "ble_app_proximity" exampled by Nordic, it indicates errors:

"D:Program FilesMDK5ARMPACKNordicSemiconductor RF_Drivers3.0.0gpiote rf_drv_gpiote.c(30): error: #20: identifier "GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS" is undefined"

"nrf_drv_gpiote_evt_handler_t handlers[NUMBER_OF_GPIO_TE+GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS];"

and

"D:Program FilesMDK5ARMPACKNordicSemiconductor RF_Drivers3.0.0gpiote rf_drv_gpiote.c(148): error: #20: identifier "GPIOTE_CONFIG_IRQ_PRIORITY" is undefined"

"nrf_drv_common_irq_enable(GPIOTE_IRQn, GPIOTE_CONFIG_IRQ_PRIORITY);"

2.解决办法

　　Find nrf_drv_config.h in your project:

 Modify following macro will ok：

#define GPIOTE_ENABLED 1

　　将下面宏改为1即可：
