Could you have a look at STM32F722 (RET6) ? 2x USB, 512k Flash i 256 RAM, should be plenty ? and available in RS-online

Re: TF Riser Revision 0 Arrives
Is there one with an RTC?

Re: TF Riser Revision 0 Arrives
It looks like this one has RTC as well. At least there is config section of RTC on STM32CubeIDE for this chip (more sections than on f105), and documentation suggest that there is one.

Re: TF Riser Revision 0 Arrives
Figured out why the mouse isnt working...although i've not actually fixed it yet.
After each keyboard interaction the GPIO port is set to input with...
amikb_direction(DAT_INPUT); // Default

Re: TF Riser Revision 0 Arrives
What chip did we finally decide on? I've completed the TF536 updates and Tf360 updates (both are on order)... next one to do is the riser.

Ok... going with the 722RET... Any layout opinions?

Re: TF Riser Revision 0 Arrives
Should we go with this?
https://uk.rs-online.com/web/p/type-a-u ... s/6741353/
or 2 x separate?
Also does anyone know anything about the floppy disk signals.. Should i wire them up to the ARM (i think i can do all the CIA stuff in the CPLD).
e.g. can the STM32 decode the raw MFM signals. We have a spare SPI port on here i figured we might try this out.

Re: TF Riser Revision 0 Arrives
The stacked USB port isnt much bigger than a PS/2 connector, if its in the same position as the kipper those lucky peeps with a 3D printed rear cover will be overjoyed!
If the floppy is a no go, could the Amiga parallel port be an option?

I would love a ParNet cable, Im having a `mare with transfering stuff onto the CD32 to try out
I dont think the CD drive enjoys me opening the case like a car bonnet to swap the CF cards but I would rather the CD die over TF330/CD32 edge connector damage.
Any streams coming up? its always time well spent seeing how you are getting on!

Re: TF Riser Revision 0 Arrives
Is the idea here to provide a floppy drive connector or to emulate the floppy on the riser? Perhaps the Gotek schematics could be of assistance here?

Re: TF Riser Revision 0 Arrives
The TF360/330 has wifi capability with the esp_slip_router.... i\ve just not managed to get it going yet. Just need to figure out how to make Roadshow work with slip. I'd prefer to use Amiga explorer that way TBH.juz400 wrote: ↑Fri Mar 20, 2020 7:49 pmThe stacked USB port isnt much bigger than a PS/2 connector, if its in the same position as the kipper those lucky peeps with a 3D printed rear cover will be overjoyed!

I've got a single SPI port on the arm available that could be wired to the floppy... maybe it will work or maybe it wont. I just want to give it the best chance.
