// TITLE:  ePWM Using Trip-Zone Submodule.
//
//! \addtogroup driver_example_list
//! <h1>ePWM Trip Zone</h1>
//!
//! This example configures ePWM1 and ePWM2 as follows
//!  - ePWM1 has TZ1 as one shot trip source
//!  - ePWM2 has TZ1 as cycle by cycle trip source
//!
//! Initially tie TZ1 high. During the test, monitor ePWM1 or ePWM2
//! outputs on a scope. Pull TZ1 low to see the effect.
//!
//!  \b External \b Connections \n
//!  - ePWM1A is on GPIO0
//!  - ePWM2A is on GPIO2
//!  - TZ1 is on GPIO12
//!
//! This example also makes use of the Input X-BAR. GPIO12 (the external
//! trigger) is routed to the input X-BAR, from which it is routed to TZ1.
//!
//! The TZ-Event is defined such that ePWM1A will undergo a One-Shot Trip
//! and ePWM2A will undergo a Cycle-By-Cycle Trip.
//!

Can you help me to see what is wrong with the Action Qualifier part of the code? Run it and say that it can not open the file.

Hi Chi,

For your query, please post your query in E2E Forum as link below.https://e2e.ti.com/TI's product line experts will answer your question.

我使用ccs 导入 clb_ex15_tile_to_tile_delay工程，运行时，CLB的中断并未进入，请问是为什么？

已经进行了Lab1~Lab4，想操作Lab21验证高频注入结果是否准确，应该如何操作？
1、如何操作进行电角度辨识

2、如何判断初始电角度辨识结束

3、如何验证电角度辨识结果的正确性？（比如给定速度，看速度反馈？）

您好，我们使用芯片自带的内部模拟量参考电压，该差分电压值与标准值0.75V有一定误差，导致AD采集值有误差。是否有什么解决方案呢？

Eirwen：

使用内部参考电压的话，要求将一个低等效串联电阻 (ESR)（低于 1.5Ω）的 2.2μF 陶瓷旁路电容器接至模拟接地。

我的振荡电路参考了Launch_Pad，与芯片手册推荐相同但波形不同，无法烧录。

Alice：

您好，

      请在您另一个同样问题帖子内查看回复。

      (+) TMS320F28379D: launchpad晶振存在1V左右直流偏置，而我采用datasheet的外部晶振接法不存在直流偏置 – C2000︎ 微控制器论坛 – C2000 微控制器 – E2E 设计支持

Warnings:cannot resolve archive

How to solve the warning: cannot resolve archive? Does it have an impact on the program?

Eirwen：

Hi

感谢您对TI产品的关注！关于cannot resolve archive这个报错，请参考下面帖子：

warning #10211-D: cannot resolve archive … no input files have been encountered

SPI配置：时钟模式2，设置传输bit数为8

我在使用过程中，可以随时修改传输bits数吗，我看库函数setcharLength可以修改传输bits数量，但是在修改前需要先禁用SPI模块，修改后再开启SPI模块；

请问”修改传输bits数“是不是必须先禁用模块再使能模块，能不能直接修改

感谢大家的回复！

f280049(100Pin)的使用485或者232类似的通讯，需要配置SCI，但是只有SCIA和SCIB两个口可以使用，实际使用中的数量不够用，在不增加其他mcu或者转换芯片的情况下 ，F280049(100Pin)有没有其他的寄存器可以配置,做为RS485一类的串口使用呢

Vivian Gao：

您好

查看下方链接的回复。

您好，
是否可以将InstaSPIN中高频注入法的算法库ipd_hfi.lib移植到28388d中？想利用这个算法库得到初始电角度，后续运动控制使用自己的算法

Vivian Gao：

您好

我们没有查到相关内容。
