See my nice TV!

Today I got a nice small 4.3" Video-TFT with PAL and NTSC Support. Of course,  I had to try it out right away :)

Btw: The SID-Emulation is now on the FPGA, not an 'external' SwinSID anymore. Sorry for the bad quality, but that's all my smartphone has to offer!

The Demo is Dawnfall by Oxyron - but you know this anyways....

FPGA meets Arduino - Part 2

After a long break I did some major updates again on my C64 on an FPGA.

First, I mounted all the parts on a wooden board, so shortcuts and broken connections should not bother anymore.

Top Left: FPGA with the C64
Top Middle: AD725 Breakout with a Lowpass-Filter for the Sound
Top Right: AV-Out
Bottom Left: IEC-Breakout
Bottom Middle: SD2IEC
Bottom Right: (that's what's new) The Control Panel

Also the SID-Socket is gone (for now), sound is replaced by an FPGA-Implementation I found on the net. I don't know who originally coded this SID-Emulation, maybe it's someone of you? Here's the URL: https://svn.pacedev.net/repos/pace/sw/src/component/sound/sid/

And I wanted to add 2 joystick-ports with paddle-support, while not loosing more I/Os for the soon to come cartridge port. The solution you see on the bottom right: An Arduino Pro Mini together with an 1.8" Color LCD, some contol buttons plus 2 joystick-ports - connected using I2C to the FPGA.

With only 2 Pins used for the I2C, I have 2 joy-ports with (soon to come) paddle support (there are some analog inputs on the arduino), and a simple control panel to reset or mute the C64, as well as turn off borders and enable some debug visuals from the VIC-Emulation. The "Menu" is used to define the default kernal image.

Joysticks are updated ~30 times/second - which is fast enough for all games.

FPGA meets ARDUINO meets C64

I always wanted to make my own Joystick - so I decided to connect an Arduino UNO together with a JoyStick Shield to the FPGA64. I know, not really my OWN Joystick, but at least I can program it the way I like (e.g. configure one Button for "UP" for Jump'n'Runs, RapidFire, WiggleMode for Decatlon .....)

Further I added one more Bit to the Video-Output, so now we have 9 Bits (3 Bit for each color). Much closer to the real thing than before!

Small but important preparations

Nono, this project is still NOT stuck! Just the pace is a little down.

To achieve the next milestone (which is an expansion port), I need to switch to another FPGA Board with more I/Os. I already have one here, but as I always tend to overread specs, I missed that there is no SRAM, but only an SDRAM on this Board.

And no, I'm really not in the mood to write an SD-Interface. So I've ordered some SRAM-ICs which I will hook up later.

In the meantime, I was able to programm and read the Flash IC (CIF) on the Board. So all Roms (Kernal, Basic, Charset) are no longer occupying valuable BlockRam.

If everything goes well, I will have an expansion port up and running still on 2012 :-D

Time passes by...fast....

Long Time no updates, which does not mean I abandonned the project.

In the meantime, I was able to find a solution to do the Level Conversion ...

This is the new FPGA-2-IEC-Board with the Level-Converter (5 Signals) on top:

(BTW: Those two boards are the first PCBs I etched myself using the method described here: http://thomaspfeifer.net/platinen_aetzen.htm)

Further I have found a new FPGA-Board with enough I/O for nice Stuff like a Cartridge Port or real Joystick ports. As the new Board does not have a VGA-Connector, so I need to make a new VideoConverter-Board too. This should keep me busy for the rest of this year....

BadCopy by Emulamer - 66% success

As I've no real updates to present.....

Emulamer striked again at the Dekadence Dataparty 2011 with "BadCopy"

As of today, BadCopy does not work 100% on any emulator yet, also not on the Chameleon.

There seem to be 3 emufuxxors (Sprite, Music, "Picture") in this demo.

And well, it also fails on my FPGA :) While the sprite is correctly hidden, and the right music is played, the "Picture" shows the wrong charset... 66% success - better than nothing.

Thank you for all the Help!

I got many Mail with inputs how to solve my problems - thank you very much for support!

So the first thing I'm gonna do is to build some level-converters as on this page:
http://www.rocketnumbernine.com/2009/04/10/5v-33v-bidirectional-level-converter/

First I will try to get the SID-Socket running with a real SID and BiDir (the current solution is "write only" to the SID).
