Green Deng：
你好，请问你是使用的TI例程吗？具体是基于哪个例程？
另外，你说的下属模式是指什么？
PS: 上传代码建议用输入框中的“插入 – 代码 – 语言：C”来进行上传
,
YE CHENG-SYUAN：
而我换成上下模式也是无法达成我想要的讯号，而例程主要是#include "F2837xD_Examples.h"
,
Green Deng：
请参考例程中的epwm_ex2_updown_aq.c：
C:\ti\c2000\C2000Ware_4_01_00_00\driverlib\f2837xd\examples\cpu1\epwm
,
YE CHENG-SYUAN：
我找到C2000Ware_4_01_00_00 ，但它无法让我下载
,
Green Deng：
无法下载会出现什么报错吗？
,
YE CHENG-SYUAN：
,
Green Deng：
你好，你是用公司内网下载的吗？是不是被公司的IT设置了限制？
,
YE CHENG-SYUAN：
我是用学校内网下载的，应该不会受到限制才对
,
Green Deng：
建议你试一下我个人网络，因为这个网站没有报告有这方面的情况，你这边无法下载极有可能是你自己的网络问题。
,
YE CHENG-SYUAN：
已经可以下载了，谢谢
