graph设置问题

2018-09-15 分类：C2000™ 32位实时 MCU 阅读(438)

請各位幫我看看為什麼我的graph觀察的波行不管怎麼設置都是錯誤的

我用訊號產生器產生一個0~1.5V左右的100HZ的弦波，但CCS上顯示的都是錯誤波形

是哪裡設置錯了嗎?

我的斷點設在這

按網上的各種設置方法設了都沒用

我用訊號產生器產生一個0~1.5V左右的100HZ的弦波，但CCS上顯示的都是錯誤波行。
没明白你的描述，讯号产生器是外部的吗？你意思是外部讯号产生器产生一个0~1.5V左右的100HZ的波形，你用MCU的ad读取，然后想在graph上观察读到的值，对否？

請各位幫我看看為什麼我的graph觀察的波行不管怎麼設置都是錯誤的

是的，敘述不清楚，請見諒。我是想測試用外部訊號產生器產生一個100hz的弦波給adc讀值，然後在ccs的graph上顯示出ad讀到的是否為弦波,謝謝

請各位幫我看看為什麼我的graph觀察的波行不管怎麼設置都是錯誤的

我用訊號產生器產生一個0~1.5V左右的100HZ的弦波，但CCS上顯示的都是錯誤波形

根据您的代码，

1. 如果输入电压为1.5V的话，(AdcRegs.ADCRESULT4>>4)*0.0007326 = ((1.5/3.3 * 4096) >>4)*0.0007326 = 0.085248，这个数相对1.689 太小。这可能是graph显示不正常的一个原因。

 If_V=(1.689-(AdcRegs.ADCRESULT4>>4)*0.0007326)*53.5;

2. 你可以利用DataLog模块来观察Graph波形，该模块可实现Four Channel Data Logger。具体应用请参考下面材料以及参考设计方案TIDM-1000中关于DataLog的代码，主要在pfc3phvienna.c & pfc3phvienna.h文件中。

DataLog的有关说明： http://processors.wiki.ti.com/index.php/GUI_Composer/Logging_Graph_Data

TIDM-1000 文件路径 C:\ti\c2000\C2000Ware_DigitalPower_SDK_1_01_00_00\solutions\tidm_1000

TIDM-1000 User guides：www.ti.com/…/tiducj0d.pdf

請各位幫我看看為什麼我的graph觀察的波行不管怎麼設置都是錯誤的

我用訊號產生器產生一個0~1.5V左右的100HZ的弦波，但CCS上顯示的都是錯誤波形

是哪裡設置錯了嗎?

回复 笨鸟:

我用方波去測試，只有1HZ的方波能看到波形，10HZ以上的方波graph到的都是錯誤的

下圖是測試外部給1HZ方波信號

下圖給10HZ方波，graph看到的波形都是錯的，我也試著調適主要幾個設置，acquisition buffer、sampling rate 、display data size也換過仿真器都沒有幫助。

請各位幫我看看為什麼我的graph觀察的波行不管怎麼設置都是錯誤的

您好 我已經將1.689給拿掉了，但還是一樣無法正常顯示波形，只有在測試1HZ方波情況下，能看到方波，10HZ的以上就完全是錯誤。
