CC2640R2F GPTimer的使用

您好，参考例程，请问hTimer = GPTimerCC26XX_open(CC2650_GPTIMER0A, &params)中，CC2650_GPTIMER0A是什么？取值范围为0-7吗？我填了一个7，提示Error[Li005]: no definition for "GPTimerCC26XX_config" [referenced from GPTimerCC26XX.orm3(drivers_cc26x0r2.arm3)]

那我第一个参数应该传入什么呢？按例程传入CC2650_GPTIMER0A，会报错

CC2640R2F上使用应该是CC2640R2_LAUNCHXL_GPTIMER0A

回复 Viki Shi:

CC2640R2_LAUNCHXL_GPTIMER0A提示我未定义，请问这个是包含在哪个头文件？

Viki Shi：

回复 梦与远方:

CC2640R2_LAUNCHXL.h，timer的使用建议参考PWMLED2这个例程

回复 Viki Shi:

使用边沿计时器的话要参考哪个例程呢？

回复 Viki Shi:

我添加了CC2640R2_LAUNCHXL.h，提示我no definition for "GPTimerCC26XX_config" [referenced from GPTimerCC26XX.orm3(drivers_cc26x0r2.arm3)]，GPTimerCC26XX_config是在哪个文件里定义的？

Viki Shi：

回复 梦与远方:

GPTimerCC26XX.h

回复 Viki Shi:

我要是想使用IOID27与timer0的引脚联系起来，要怎么配置呢？

通过PINCC26XX_setMux();函数

这是我之前一个下降沿检测的例子，供参考：
