Re: TF CD32 Riser Revision 2 Design Complete
Posted two out to @arkadiusz.makarenko today. One has the video buffer chip on the other doesnt. I only had two chips.

Re: TF CD32 Riser Revision 2 Design Complete
I am still slowly working on it, but I must say that it is getting more complex than I initially thought.
At this moment I am working on usb->adf->MFM side of things.
PS.
I am still waiting for PCBs.

I’m guessing the xmas post slowdown has hit then.

Re: TF CD32 Riser Revision 2 Design Complete
That will be fun. Remember the floppy idea was "experimental". I simply put those pins on the ARM because they were not doing anything else.arkadiusz.makarenko wrote: Tue Nov 10, 2020 6:39 pm I am still slowly working on it, but I must say that it is getting more complex than I initially thought.

No problem!

I think my objective on this revision is to prove that FlashFloppy can be adapted and work at all with other stuff already on this microcontroller.
My family is self isolating after school outbreak, so it is good to have some project to focus on.

Re: TF CD32 Riser Revision 2 Design Complete
@terriblefire
I am quitting on straight port of FlashFloppy. Too many hardware and custom class dependencies.
I have ported/hacked 7 classes, and I still discover another few to make it work ... this will not work as I use different libraries and there is plenty of direct asm calls.
I am not quitting idea but I need to actually understand it better and rewrite it from bottom up. and then lift the code which manages adf images, generate signals, and control timings. But all the low level classes need to be written from scratch.
Great thing is that Kier has full Git history, I can trace from bottom up how he started and solved issues at the same beginning. Now firmware is super universal with support for so many platforms and configurations which makes it great to use, but extremely difficult to port.

Sorry, can't log in using Facebook.
I built new card today.
I haven't ordered 100k resistors on video line (installed biggest I had 20k for now), but video is badly overexposed and colours do not match, video is very soft.
I will try with 100k in few days and will let you know.
PS.
I still need to work on cd32 gamepad support, it does work on ATK, but doesn't pass gamepad detection. Need to fix this. And few other bugs line stuck buttons in override etc. I don't handle registers correctly. Need to fix it.
