LCD text output

Other Parts Discussed in Thread: TMS320VC5505

Hi,

I'm using the TMS320VC5505 EVM for a University Project. I would like to generate the output of a simple text on the Display of the board.

I have already looked at the csl example (LCD_LIDD_OELD) for LCD output. As I have understood it, the cmdWrite-function is writing the adress of a certain command into the framebuffer. This tells the lcd controller to expect n dataWrite-functions specifying a number of points and colours (this is dependant on the command to be executed). There are examples given for rectangles and circles that I have understood and have been able to adjust as I needed them.

Now, I would like to create text output. I have seen that the CSL package actually includes a font table for the LCD, but I cannot figure out how to use them. I have not been able to find any helpful references in the LCD Controller's user guide nor in the CSL reference guide. Could you please tell me how I can work with the table or point me to an example project using this table?

If there is no such thing, maybe you have an example code for the program that is executed when switching the board on. This program has a text output on the LCD, and seeing how this is generated would help me greatly.

Thank you for your help.

 

Yours,

Juliane

    Juliane,

    Have you run the lcd example 4 which displays different texts on the OLED (it is under . I think you can look at the example code to understand how to use the font table and you can make your own font table if you want after you understand it.

    it is under "\ccs_v3.3_examples\lcd\example4\" or "ccs_v4.0_examples\lcd\CSL_LCDC_TextDisplayExample\"

    Best Regards,
