multi language support and rendering by graphics Library TIVA ware

smit majithia

Dear Sir,

I want to display different languages on LCD display . I have gone through many post and the document of the graphic library but all are confusing.

I uses the String table method.

So i made .csv as per lang_demo project and did the same perfectly i made .c and .h by using the mkstringtable and it did perfectly as per lang_demo project.

now i use the functions

GrStringTableSet, GrLanguageSet, GrStringGet

it rendered the English language correctly,

But when i change the Chinese lang then it shows (.) Dots instead of the fonts of Chinese as per .csv

How Could i render the Chinese fonts or korean fonts in my LCD please suggest me the solution.

// // Set the string table. // GrStringTableSet(pucTablestrings); // // Set the current language to English(US). // GrLanguageSet(GrLangEnUS);

Hello Smit,

Did you use UTF8 encoding while entering the Chinese characters into the .csv file? Looks like that is required for Asian languages (as per the Readme of the "lang_demo" example).

Which board are you using? TI board or custom board? If TI board which one?

The "lang_demo" example already has stings in Korean and Simplified Chinese. The "language.csv" files also has strings in both these languages. Have you tried this example?

Thanks,
Sai

Dear Sai,

I have seen that code of lang_demo.

I m using custom Board has TM4c129Ncpdt uC.

yes i have used the UTF8 encoding i can share with you below.

But i dont know how to print the Chinese characters on Screen!!lang.xlsx

Hello Smit,

I am not able to generate the right "language.c" and "langremap.c" files with the file you attached in the previous post.

I modified the Makefile in the folder "./third_party/fonts/lang_demo" to pick this new file you provided. When I execute the rule to generate the "language.c" file, no errors are reported but when I execute the rule to generate "langremap.c" , lot of errors are generated. These errors indicate that "mkstringtable" does not recognize the content of the .xlsx file while remapping. The "language.c" generated does not have any valid data.

So I changed the format of the file to .csv (I saved this file as a .csv file using Excel) and then open the file in a text editor (Notepad++), which recognizes UTF-8 format. Only the English characters are visible, and all of the non-English characters are represented by the character"?", which indicates that they are not in UTF-8 format.

When I open the "language.csv" file provided in TivaWare with the same editor, I can see the Chinese, Korean and Japanese characters.

I would recommend, using a text editor that recognizes UTF-8 format to create these characters and save the file as .csv, instead of using Excel. Then try to create the langremap.c file and see if it works.

Thanks,
Sai

Hello Sai,

how to make sure that the file is compatible UTF-8 encoding.

I have made it with the google sheet and download as .csv format but as you told me that it is not compatible then how to check the compatibility prior to put it in code?

and is remapping required??

bcoz in the lang_demo code they did remapping and also normal method too so i m bit confused what should i do for my application remapping or normal??

Hello Sai,

i have made files" languguae.c" &"langremap.c" Please see to it and i have attached the UTF-8 .txt of the same. please see to it and please suggest me the next step of the same.

It is the weekend w/in the USA - support (may) be delayed.

If you create a very small, test file - and execute that - you may develop further insight - helpful to vendor's tech staff. The advantage of the small file is less: time/effort on your part - which should enhance "trial & error" finds/solutions...

Hello Smit,

The lang_utf.txt file look good. Did you check, if the "langremap" is working (when you include it in the "land_demo" example)?

Thanks,
Sai
