Displaying Charater on Screen

Question

Hi,

I am working on a project using ZYBO and i want to print different characters on Screen. So, can anyone please tell me how can I print a single character on screen without coloring each character pixel by  pixel? And also is there anyway to use ascii to print characters on screen directly? if there is any such way then please let me know...

 

Thanks,

Thanks for taking interest in my question sir.

I'm using LCD or more specifically LG Flatron 1280x1024 with Zynq-7000 SoC Development Board - Digilent Zybo Z7.

Hi @Sami Malik,

I am not familiar with that particular display. Presuming this is the display that you are using; the display does not have an HDMI input and the Zybo Z7 only has an HDMI output, so you would need some sort of external adapter that could change from HDMI signals to either DVI compatible or VGA signals. Alternatively, you could use something like the Pmod VGA to send out the appropriate signals to the monitor. There are a couple of demos for both of these with the Zybo Z7 available on it's Resource Center, though I do not think either of the demos have specific ways built in to do manipulate individual pixels or send ASCII characters though.

Let me know if you have any questions about this.

Thanks,
JColvin

Hi @Sami Malik,

I was directed to a project that had done some ASCII characters on an external display for the Basys 3; they did not test it with a Zynq based board, but the project was done in HDL so it should be fairly easy to implement on the Zybo Z7: https://github.com/artvvb/VGA_SERIAL.

Thanks,
