1.引入头文件
#include "nrf_temp.h"
2.定义变量
int32_t volatile temp;
3.在主函数中的处理
/** * @brief Function for main application entry. */ int main(void) { uint32_t err_code; bsp_board_init(BSP_INIT_LEDS);
const app_uart_comm_params_t comm_params = { RX_PIN_NUMBER, TX_PIN_NUMBER, RTS_PIN_NUMBER, CTS_PIN_NUMBER, UART_HWFC, false, #if defined (UART_PRESENT) NRF_UART_BAUDRATE_115200 #else NRF_UARTE_BAUDRATE_115200 #endif };
APP_UART_FIFO_INIT(&comm_params, UART_RX_BUF_SIZE, UART_TX_BUF_SIZE, uart_error_handle, APP_IRQ_PRIORITY_LOWEST, err_code);
APP_ERROR_CHECK(err_code);
while (true) { NRF_TEMP->TASKS_START = 1; /** Start the temperature measurement. */ /* Busy wait while temperature measurement is not finished, you can skip waiting if you enable interrupt for DATARDY event and read the result in the interrupt. */ /*lint -e{845} // A zero has been given as right argument to operator '|'" */ while(NRF_TEMP->EVENTS_DATARDY == 0) { // Do nothing. } NRF_TEMP->EVENTS_DATARDY = 0; // clear flag /**@note Workaround for PAN_028 rev2.0A anomaly 29 - TEMP: Stop task clears the TEMP register. */ temp = nrf_temp_read()/4; /**@note Workaround for PAN_028 rev2.0A anomaly 30 - TEMP: Temp module analog front end does not power down when DATARDY event occurs. */ NRF_TEMP->TASKS_STOP = 1; /** Stop the temperature measurement. */ printf("temp is %d\n",temp); nrf_delay_ms(1000); }
}
