[Ql-Users] QL-VGA case article
I've written an article on my blog about making a case for my QL-VGA prototype. Important to realise that this is a prototype board - the finished product may differ a little. But it was quite easy to do and will protect the board and looks tidier than a bare board. https://dilwyn2.wordpress.com/2020/03/19/ql-vga-case/ Dilwyn ___ QL-Users Mailing List

I try to inform all 4 major venues (this list, the English forum, the German forum and Facebook), which is a bit of a pain but they all have distinct groups of users. But while I do get the rejection of Facebook I encourage joining at least the English forum, it is a very lively place (between 5 to 30 posts a day I would guess. If that is too much, the forum is split into hardware/software/etc. so easy to filter for one's taste) and unlike Facebook it is exclusively operated by QL enthusiasts. I uses an RSS reader to read the forum, so I get to see new posts when they arrive, just like in an eMail list, and can then decide to chime in or not. This way reading it is very comfortable without having to manually poll the site for changes, which in the past was my biggest grievance with web forums. Marcel ___ QL-Users Mailing List

Re: [Ql-Users] QL-VGA
Indeed, one might say it's more of a mark up decription of what you would like to see the hardware been rather than a S/W program to run on the H/W. Sounds so pedantic doesn't it ;-)JA On Thursday, 9 January 2020, 22:11:31 GMT, Norman Dunbar via Ql-Users wrote: See!

Re: [Ql-Users] QL-VGA
Thanks John. I get that it's a software description of some hardware. This is the first time I've come across it. I might spend some time looking into it - if/when MrsD allows - just to satisfy my own curiosity. Not that I'll be doing any hardware design though.

Re: [Ql-Users] QL-VGA
Yes , think of it of a high level and standardised method of describing the configuration of your FPGA hardware rather than a program for it to execute.For example I could define logic blocks to act as flipflops and attach the input to one pin and the out put to another they don't need to interact with each other to perform this so the config maybe sequential once loaded in to the FPGA the resultant Logic config works in parallel or as parallel as you wish to design for!JA On Thursday, 9 January 2020, 13:42:00 GMT, Norman Dunbar via Ql-Users wrote: Hi Marcel, On 09/01/2020 10:50, Marcel Kilgus via Ql-Users wrote: > Well, it's a bit like programming, the difference is just that > basically all lines execute at the same time!

If > you have time and inclination of course. Well, it's a bit like programming, the difference is just that basically all lines execute at the same time! If you want something to execute sequentially you have to implement a state machine. That's the gist of it. If you have a base clock and base everything off of that things are pretty clean and work nicely. But if you have different clocks things get weird very quickly. For example I tried implementing an Aurora card for the MiSTer FPGA board, but I couldn't get the pixel clock to change reliably, it only worked like 50% of the time. For QL-VGA I use a base clock of 130Mhz, which divides nicely into the 10Mhz QL pixel clock and the 65Mhz VGA pixel clock, so nice and clean. Debugging is either done by simulating your code on the PC or by actually compiling a complete logic analyzer INTO your design so it runs on the same chip next to your own logic :-o You can then read out your signal data using the JTAG interface. That is pretty cool. For a pretty simple example the QL-SD code is open source if you want to see how this looks like: https://www.kilgus.net/soft/qlromext_spi.v This is so small it compiles to a CPLD chip, which is basically a GAL on drugs. But the way to code is exactly the same. Cheers, Marcel ___ QL-Users Mailing List
