[游戏开发]NRF52832内嵌温度测量操作

无蓝牙协议栈温度测量

• 引入#include "nrf_temp.h"头文件
• 调用nrf_temp_init()初时化MCU温度单元
• 温度转换并打印结果

        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;

        /**@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. */

        NRF_LOG_INFO("Actual temperature: %d", (int)temp);
        nrf_delay_ms(500);

        NRF_LOG_FLUSH();

带蓝牙协议栈温度测量

• 引入#include "nrf_temp.h"头文件
• 调用nrf_temp_init()初时化MCU温度单元
• 温度读取使用sd_temp_get函数进行温度读取

 (void)sd_temp_get(&temp); //ben
 temp >>= 2;
 NRF_LOG_INFO("Actual temperature: %d", (int)temp);

• 运行结果
