器件型号：CC1310 主题中讨论的其他器件： HDC2010
您好！
我的问题是、我 使用 Power_SHUTDOWN (0、0)将 CC1310置于关断状态
我使用 GPIO 上的 IOC 唤醒、该功能 工作正常...一次...然后器件无限期保持关断状态。
在测试期间断开调试器。
任何指针都被赞赏。
下面是有关重现此问题的一些详细信息：
在我们的应用中、我们将 HDC2010传感器连接到 CC1310
HDC2010将中断引脚从高电平切换到低电平、以便在通过 I2C 准备好新的温度和湿度数据时触发
我们使用该引脚作为 CC1310的唤醒引脚、将数据传输到收集器、然后在数据采样之间进入关断状态。
采样率为每10秒一次
在硬件方面、我们使用 BOOSTXL-BASSENSORS 分线板与 CC1310 Launchpad
H_INT 是如图所示的唤醒引脚、它被配置为 IOID_25、因此我们知道硬件工作并且分配了正确的引脚。
在验证发生的情况方面、
Smart RF 屏幕截图下方仅显示 收集器接收到的2个数据包
第一个数据包在发送器的第一个 POR 时、第二个数据包是第一个数据包、并且我们只能看到从关断状态唤醒。
请注意、它们之间的间隔正确为10秒
下面的 H_INT 引脚屏幕截图也显示它正确变为高电平、并在 HDC2010通电时保持高电平。
在 t=0sec 时、引脚在 HDC2010上电时变为高电平
在 t=10sec 时、变为低电平、太快、无法在宽范围时基上看到、但 CC1310正确唤醒、读取 int 状态、引脚恢复为高电平。
但是、CC1310不会在下一个采样间隔(t=20秒)唤醒
因此、总高电平持续时间为20秒。
以下是代码、
唤醒引脚在 CC1310_LAUNCHXL.h 中定义为#define BOARD_HDC_DRDY IOID_25
