器件型号： CC2340R5
Thread 中讨论的其他部件： Sysconfig、、 LP-XDS110ET、 ENERGYTRACE
我目前正在处理一个使用 CC2340R52N0RGE 芯片的工程、在配置低功耗模式时遇到了一些问题：
1、SysConfig: FreeRTOS、 250kbps O-QPSK、PowerCC23X0_standbyPolicy、启用空闲挂钩功能
2、在 main_freertos.c 中、定义的低功耗标志和低功耗唤醒信标：
//-- =0: normal operation, =1: in low-power state
volatile uint8_t g_low_power_state = 0;
//-- Low-power wake-up semaphore
SemaphoreHandle_t g_wakeup_sem = NULL;
//-- Release semaphore
xSemaphoreGive(g_wakeup_sem); 3、串行端口收到低功耗命令后：
设置。
g_low_power_state = 1 当线程检测到
g_low_power_state == 1时、它不会释放信号。 然后、该线程将在以下位置阻塞：
xResult = xSemaphoreTake(g_wakeup_sem, portMAX_DELAY);4、通过按钮 (DIO6) 唤醒后、释放信标并且程序恢复运行。
我可以清楚地看到,所有其他线程都被阻止,系统已进入空闲线程,但芯片的电流消耗保持在 10mA 左右。
请帮助检查阻止 CC2340R52 进入低功耗模式的不正确内容。
