    Hi,


    I am not familiar with these example design, so I may only give the best support for this issue.


    Also, I advise that you consult Terasic on your project for your DE10 board.

Hi EBERLAZARE_I_Intel,

connect hardware

The first, I have looked for examples of uart of this IP but there are very few examples and only got 1 example made with the GHRD project from this links:
1. https://blog.csdn.net/weixin_43649647/article/details/121069892

2. Page 140 to page 155: https://www.intel.com/programmable/technical-pdfs/683130.pdf

3. Project example for Nios (but I must use with GHRD): https://www.intel.com/content/www/us/en/design-example/715139/cyclone-v-uart-rs-232-maximum-baud-rate-reference-design.html?wapkw=uart

Secondly, I got project GHRD from Terasic (CD Rom) or You can get at link I was upload:

https://drive.google.com/file/d/1Bse1dQUNYEjjC0GkylL1VpXxlSVzFtoI/view?usp=sharing

Also, I think this problem may be caused by asynchronous transfer speed (baundrate) of the two devices or another error? But I don't know how to fit it. please help me to fix this error of wrong data transmission.

Thank you very much.

Regards,

Kai
