General Purpose I/O: The general purpose I/O is organized as one port enabling access and control of the 32 available GPIO pins through one port. Each GPIO can be accessed individually with the following user configurable features:  Input/output direction  Output drive strength  Internal pull-up and pull-down resistors  Wake-up from high or low level triggers on all pins  Trigger interrupt on all pins  All pins can be used by the PPI task/event system; the maximum number of pins that can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels  All pins can be individually configured to carry serial interface or quadrature demodulator signals PA control: A logic signal is needed to enable/disable PA/LNA part, P0.20 is used to achieve this purpose. Set P0.20 to high will enable PA/LNA. Set P0.20 to low will disable PA/LNA to deep sleep mode. As the most basic use case, simply set the P0.20 to high will enable PA/LNA part always. If you need to get lower power consumption, you need to accurately control the timing of the PA/LNA when it need to work, in accordance with the provisions of the timing will be closed. In order to achieve this goal, need to know exactly time to control the PA/LNA. By calling the Notify Radio() function, you can know when the RF activation, resulting in the appropriate timing to control P0.20. #define PIN_5518CTR 20 for (;;) { if(m_radio_active_flag)//enable PA { m_radio_active_flag=0; nrf_gpio_pin_set(PIN_5518CTR);//pin 20 err_code = app_timer_start(m_apps_timer_id, APP_TIMER_TICKS(10, APP_TIMER_PRESCALER) , NULL);//app_timer 10ms APP_ERROR_CHECK(err_code); COPYRIGHT ©2016 ALL RIGHTS RESERVED XunTong Tech TEL: +86 755 26675941 E-mail: nrf@freqchina.com 4
} if(apptimer_timeout_flag)//disable PA { apptimer_timeout_flag=0; nrf_gpio_pin_clear(PIN_5518CTR); } power_manage(); } We have modified the source code ble_radio_notification.c that provided by nRF51 SDK, to achieve this purpose. The modified ble_radio_notification.c is located in the directly \nRF51_SDK_9.0.0_2e23562_5518PA_DEMO\components\ble\ble_radio_notification of source code package we provided. By add the ble_radio_notification.c file to the project, the Radio Notify() function can be used to detect if RF is active, below is the key code for the usage of Radio Notify() function: bool m_radio_active_flag=0; void ble_radio_active_evt(bool radio_active) { m_radio_active_flag=1; } static void radio_notification_open_init(void) { uint32_t err_code; err_code = ble_radio_notification_init(NRF_APP_PRIORITY_LOW, NRF_RADIO_NOTIFICATION_DISTANCE_800US, COPYRIGHT ©2016 ALL RIGHTS RESERVED XunTong Tech TEL: +86 755 26675941 E-mail: nrf@freqchina.com 5
ble_radio_active_evt,1); APP_ERROR_CHECK(err_code); } The following main function is an example that to show you how to enable PA/LNA part in your project: int main(void) { uint32_t err_code; app_timers_init(); nrf_gpio_cfg_output(PIN_5518CTR); nrf_gpio_pin_set(PIN_5518CTR); nrf_delay_ms(2000); ble_stack_init(); gap_params_init(); services_init(); advertising_init(); conn_params_init(); err_code = ble_advertising_start(BLE_ADV_MODE_FAST); APP_ERROR_CHECK(err_code); radio_notification_open_init(); // Enter main loop. for (;;) { if(m_radio_active_flag)//enable PA COPYRIGHT ©2016 ALL RIGHTS RESERVED XunTong Tech TEL: +86 755 26675941 E-mail: nrf@freqchina.com 6
