CC2340R5: 如何获取供电电压

?? ?

Prodigy 30 points

Part Number: CC2340R5

使用：BatteryMonitor.h

函数里面调用，

#include <ti/drivers/BatteryMonitor.h>

BatteryMonitor_init();

currentVoltage = BatteryMonitor_getVoltage();

编译报错：

undefined first referenced
symbol in file
--------- ----------------
BatMonSupportLPF3_config C:/ti/simplelink_lowpower_f3_sdk_7_20_01_10/source/ti/drivers/lib/ticlang/m0p/drivers_cc23x0r5.a<BatMonSupportLPF3.c.obj>

想要获取供电电压，目前这样操作是合理的啊？是否有其他方法可以获取到供电电压。

您好，

?? ? 说：
目前这样操作是合理的啊？

可以的。

根据错误，检查编译器和链接器中是否包含头文件路径；并检查 BatMonSupportLPF3_config 是否定义（可能只是声明了但没有定义），定义了才会分配内存。

点击此链接访问总体概述：https://c-faq.com/decl/decldef.html

可能是链接器没有找到函数定义。

这个应该是驱动里面的问题，这个是.a文件里面，BatMonSupportLPF3_config 我应该怎么定义，是什么类型的呢

您可以尝试删除源文件中的 extern

这个不是在.a里面吗？我在工程里面都找不到BatMonSupportLPF3_config这个呢。

C:\ti\simplelink_lowpower_f3_sdk_7_20_01_10\source\ti\drivers\batterymonitor\BatMonSupportLPF3.c

修改如下

//extern const BatMonSupportLPF3_Config BatMonSupportLPF3_config;
const BatMonSupportLPF3_Config BatMonSupportLPF3_config;

但是还是编译报错。

题目中的错误表明在编译过程中找不到符号 BatMonSupportLPF3_config 的定义，可能是由于链接时缺少对相应的库或资源文件引起的。

您先查看一下 Include Options 里面是否包含了该路径：C:/ti/simplelink_lowpower_f3_sdk_7_20_01_10/source/ti/drivers/lib/ticlang/m0p/drivers_cc23x0r5.a<BatMonSupportLPF3.c.obj>

另外您使用的哪一个例程，能否把详细的报错信息贴上来。
