Honored ContributorVGA Calculator Display using VHDL
All right, so I'm trying to make a floating point calculator using VHDL, and basically, I want to first make the display.
I want this calculator to display on a VGA monitor, and before I start configuring the calculating part of this project, I want to simply make a calculator actually show up on the screen with the function names. The functions will be Add, Subtract, Multiply, Divide, and Exponents (e^x). I'm using an Altera DE2 board, and I was wondering if anyone could help me with this? I really appreciate it! -CMN11 Replies

I’m working on a floating-point calculator in VHDL for my Altera DE2 board, and I want it to display on a VGA monitor with functions like Add, Subtract, Multiply, Divide, and Exponents. I’ve already set up a VGA controller, but I’m struggling with how to effectively display the calculator interface on screen especially how to use a buffer for pixel data. Could you explain with an example of how to implement this? Also, once I understand the display logic, I eventually want to extend it toward practical tools like a price bond calculator where users can enter values and see results directly on the VGA screen.
