From: Giorgos Tzampanakis on 26 Jun 2010 13:41 I want a simple bitmap font to use in my project. I'm looking into using a 80x25 or 80x24 format. Where can I get a font like this in an easy format to incorporate into my project?

So, is 80x25 the LCD pixel H/V or is that the number of characters on the screen. Are you using an FPGA to move the pixels to the screen or a cpu. So many questions, no answers. hamilton

I will use a CPU implemented on the FPGA to show the characters.

Where can I get a font like > this in an easy format to incorporate into my project? What is the screen resolution or, in other words, the size of the character cell. If you want something like we had 30 years ago, find the ROM patterns for the MCM6674 or MCM6675. The data sheet is, for example, available from http://www.datasheetarchive.com, including bit pattens. That is a 128 character, 9x7 with descenders. If you are short on memory store it the MCM6674 way, as 9x7 plus one extra bit (see the triangle in the corner) to lower the character by two rows. Otherwise, store it as 11x7 or, to fit in a normal ROM, 16x8. (It fits nicely in a 2716.) -- glen |
