是的、我使用传感器控制器示例尝试了链接线程中提供的指导、并成功获得闪烁 LED 示例的输出。 我需要定期读取 ADC。
我创建了新的服务和字符来读取16位 ADC 值。
SC 集成到 CCS 代码中，成功构建并上载，没有错误。 阈值的 LED 操作正常、但无法读取正确的 ADC 值。
我附加了 simpleperipheral.c 的以下代码

您好、Sai、
感谢您提供的详细信息。 您看起来是在正确的方向上。
当您说"我无法读取正确的 ADC 值"时、这是否意味着该值卡在0 (或任何其他值)、或者该值不准确？ 如果在 processTaskAlert()函数中停止执行，是否在 MyData 中有预期值？
如果前面的内容 没有帮助、我建议您首先将传感器控制器代码与不太复杂的项目(例如空项目)集成、这样您就可以验证 ADC 读取工作是否符合预期。
此致、
请参阅下面的博文。 博客中使用的 SDK 很旧、因此需要进行调整。

感谢您分享@Markel。 我跟在你的教学中。 我成功构建并运行了代码。 但我无法在 ble app 中读取 ADC 值、它显示为零。
以下是我的代码：

您好、Sai、
您似乎已将传感器控制器项目正确集成到 CCS 项目中。 下面是一些问题。 您能否将非 BLE5简单外设示例程序作为基础进行尝试。 也不建议使用使用 CC2640R2F 的 BLE5堆栈。
博客文章中的程序是 simple_poter。 安装 SDKv3.30、并将应用程序和堆栈项目导入 CCSv9.20、同时使用复制到工作区选项。 它可以正常工作、我只是对它进行了测试。 简单电位器不使用基于 RTC 的执行调度。 它使用应用周期计时器通过传感器控制器读取电位计。
另一件事是、许多 TI BLE 项目或产品开发使用简单外设并进行修改。 我要做的是在将简单外设示例导入到 CCS 工程之前、将其正确重命名为简单电位器。 然后、我准备低功耗示例程序。 这似乎需要大量工作、但这是必要的。 我已经为此发布了一篇博文。

您好、Sai、
我再次查看了您的原始代码。 您所做的错误是处理 Event_post (syncEvent、SP_SCTASK_EVT)；。 发布事件时，应 在 SimplePeripheral_taskFxn()中处理该事件，如下所示。
void SensorController_taskalertCallback(void){
uint32_t bvAlertEvents = 0;
// Clear the ALERT interrupt source
scifClearAlertIntSource();
bvAlertEvents = scifGetAlertEvents();
if(bvAlertEvents & BV(SCIF_ADC_LEVEL_TRIGGER_TASK_ID))
{
// ... Access Sensor Controller task data structures here ...
// adcData = scifTaskData.adcLevelTrigger.output;
adcData = scifTaskData.adcLevelTrigger.output.adcValue;
}
// Acknowledge the ALERT event
scifAckAlertEvents();
Event_post(syncEvent,SP_SCTASK_EVT);
}
static void SimplePeripheral_taskFxn(UArg a0, UArg a1)
{
// Initialize application
SimplePeripheral_init();
// Application main loop
for (;;)
{
uint32_t events;
// Waits for an event to be posted associated with the calling thread.
// Note that an event associated with a thread is posted when a
// message is queued to the message receive queue of the thread
events = Event_pend(syncEvent, Event_Id_NONE, SP_ALL_EVENTS,
ICALL_TIMEOUT_FOREVER);
if (events)
{
ICall_EntityID dest;
ICall_ServiceEnum src;
ICall_HciExtEvt *pMsg = NULL;
// Fetch any available messages that might have been sent from the stack
if (ICall_fetchServiceMsg(&src, &dest,
(void **)&pMsg) == ICALL_ERRNO_SUCCESS)
{
uint8 safeToDealloc = TRUE;
if ((src == ICALL_SERVICE_CLASS_BLE) && (dest == selfEntity))
{
ICall_Stack_Event *pEvt = (ICall_Stack_Event *)pMsg;
// Check for BLE stack events first
if (pEvt->signature != 0xffff)
{
// Process inter-task message
safeToDealloc = SimplePeripheral_processStackMsg((ICall_Hdr *)pMsg);
}
}
if (pMsg && safeToDealloc)
{
ICall_freeMsg(pMsg);
}
}
// If RTOS queue is not empty, process app message.
if (events & SP_QUEUE_EVT)
{
while (!Queue_empty(appMsgQueueHandle))
{
spEvt_t *pMsg = (spEvt_t *)Util_dequeueMsg(appMsgQueueHandle);
if (pMsg)
{
// Process message.
SimplePeripheral_processAppMsg(pMsg);
// Free the space from the message.
ICall_free(pMsg);
}
}
if (events & SP_SCTASK_EVT)
{
MyData_SetParameter(MYDATA_DATA_ID, MYDATA_DATA_LEN,&adcData); //ADDED

}
}
}传感器控制器可以与主应用并行运行。 使用传感器控制器非常有利、尤其是当您对模拟传感器进行多次采样并在将数据发送到主应用之前对其进行处理时。
当没有事件时、主应用程序将进入待机模式。 一个事件示例是蓝牙广播、应用事件。
-kel
adcData 需要是最上层的、并且对所有 c 函数都可见。
静态 uint16_t adcData = 0；//已添加
SimplePeripheral_taskFxn()中的代码需要与此类似
IF (事件和 SP_SCTASK_EVT)
｛
MyData_SetParameter (MyData_data_ID、MyData_data_LEN、&adcData)；//添加
｝
您可以在 MyData_SetParameter 和 watch 变量 adcData 中添加断点。
-kel
是的、我将 adcData 初始化为全局变量。
我发现我们需要插入此代码，
"IF (事件和 SP_SCTASK_EVT)
｛
MyData_SetParameter (MyData_data_ID、MyData_data_LEN、&adcData)；//添加
｝"
在该 IF 条件之后
"IF (事件和 SP_queue_EVT)
｛
｝"
您似乎错过了"IF (EVENT & SP_SCTASK_EVT)"之前的一个"｝"
非常感谢 Markel 的帮助。
现在我能够读取 BLE 数据。
