IO中断函数中不能执行RF命令吗？

使用 launchpadCC1310 想按下button0是发送一条TX Packet，在GPIO_Button0_Interrupt函数中执行RF_runCmd发送TX命令时返回值为0。

Viki Shi：

这应该是卡在那了，你单步调试一下，看能走到下一条语句吗

Chen Jian：

下面的GPIO_toggle能执行，随后就卡死了

先屏蔽button部分代码，只跑RF，能正常发送吗？

Chen Jian：

回复 Viki Shi:

不在按键中断函数中可以执行的，返回值也正常

请问你的例程是否参考frPacketTX？此例程是持续发送，而你的要求是“按下button0是发送一条TX Packet”，请排查下是否RF core一直在发送中

挂了的图片；

直接在主函数中连续发送没有问题；

你在上面代码中持续发送当然没问题，就这一个任务。你现在的目标不是实现按下button发送一次吗？如果这里还持续发送，那程序不就一直在这里循环了

Chen Jian：

回复 Viki Shi:

是的，我想实现按下button发送一次吗？这样可以实现吗？或者我之前的做法有问题吗？
