UART driver for QDOS/SMSQ

Postby Dave » Fri Apr 13, 2018 10:57 pm

Hi all,

I'm looking for a UART driver that will work with a fairly standard 68681 or 28L92 DUART. They're pin compatible and should be driver compatible.

Is anyone aware of any existing code that can run these?

Looking to release an economical, fast serial card as quickly as possible but hit a bit of a roadblock. A couple of other projects are hung up waiting on this.

Any help gratefully accepted. This is not an idle request. Hardware awaiting waiting driver.

Jan Wrote a driver for the 6850 ACIA as far as I recall. Maybe if the source is available it could be modified. A uart is just controlled via its registers after all.

I think he has a Github page, maybe look for his SER3 driver there.

I have his github bookmarked - there's no serial driver there. He does use an 8255 in his EPROMmer, but that isn't directly applicable.

The SER3 driver source is now at https://github.com/janbredenbeek/QL/blo ... M/ser3.asm - have fun with it.

Thank you for reaching out to me here and in email.

Yay, GPL3! The hardware would also be open hardware.

I'm just not a 68K assembly programmer.
