There's also an open source Verilog for a flash controller that you can find here. You'll find it valuable if you wish to access the flash from within your design, either to read from, erase, or rewrite/program it. Dan

Just to close the discussion, and for anyone else reading, here's the command that turned character 0x01 into a backslash. Note the required <ESC>[3p at the end: <ESC>[0;16;8;4;2;1;0;0;1d<ESC>[3p Dan

JColvin, I finally got your example working. May I highly recommend that you update your PmodCLS reference manual? The example given in the PmodCLS manual doesn't work--or at least it didn't for me. I needed to send an <ESC>[3p command after defining the character in order for it to show up on the screen. Nothing in the reference manual suggested that would be necessary. Indeed, if you could do a bit better of a job explaining the nature of that character table that is programmed into ROM from EPROM or RAM, I would appreciate it. For example, is this just the 5 (or is it 6?) user definable characters that get programmed, or is an entirely new character set being programmed? In other words, is there anyway to change the meaning of the backslash, or do I just need to suffer with using a user definable character of which (according to the MPIDE code you reference) it looks like there are only six of? Thanks, though, for your help. If the MPIDE code hadn't also done the <ESC>[3p command, I would've never gotten it! Dan

Hello! I have just recently purchased a PModCLS board. After a bunch of hard (fun) work, I have it mostly up and running via the SPI port. As a sample project, and at the kids' suggestion, I am using a mouse (connected to a Basys-3 board) to drive the display to create 'eyeballs' that follow the mouse around, or that change their mood as the mouse moves. It's a fun project, and a fun demonstration of what the board can do. My problem is that I'd like to use the backslash as one of the text-art characters in the eyebrows, and everytime I send the device a backslash a ... foreign character appears. (It looks like a 'Y' with two horizontal bars through it.) I know that the reference manual discusses being able to reprogram characters. Can you tell me if all of the characters can be reprogrammed? In particular, can I reprogram the backslash back into a backslash? Or can I only create some special purpose characters using a limited part of the ASCII character set? Thanks! Dan
