[参考译文] LAUNCHXL-CC1310：ADC 数据存储问题

https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1214509/launchxl-cc1310-adc-data-storage-issues

嗨、团队：

我目前遇到一些问题，需要寻求帮助。 我现在计划使用 TI15.4的收集器和传感器例程发送收集到的 ADC 数据。 我计划一次发送100个 ADC 数据、因此我将使用时钟例程生成一个计时器、每10ms 收集一个 ADC 数据、并将 ADC 数据存储在一个包含100个元素的定义数组中。 然而、当我从传感器向收集器发送数据时、收集器端接收的数据全部为零(我采集的 ADC 具有3.3V 的电压)。 我想问一下原因在哪方面、下面的代码是：

目前，问题出在阵列的接收缓存端。

ADC‘读取数据、但在缓存"empSensor.tempSensor.ambientetp"数组后、数组中的值为0
