I wonder if it's possible to optimize the READ routine like this:

Code Select Expand

;### DSWRED -> read 8 bytes from the Dobbertin Smart Watch
;### Input      DE=destination address
;###            ROM is already selected
;### Destroyed  AF,BC,DE,HL
dswred  ld b,8
        lh hl,#c004
        di
dswred1 ld a,128
dswred2 rr (hl)
        rra
        jr nc,dswred2
        ld (de),a
        inc de
        djnz dswred1
        ei
        ret

The RR (HL) command will do a write to #c004, would this disturb the communication??

[TFM]

Looks good. Of course it's the most fun to make own routines.     IIRC I unlooped it to speed it a bit up. But it's basically the same...


Ok, now on my own PC I could dig that out...

Ok here is a patched TIMEROM+ which scans ROMs 1-127. I call it TIMEROM#  [emoji23]


Let me know it it works please! 

I am not sure if anyone else has tested this. So I did.

As you can see it works [emoji3]  but the year is screwed up, unless " ;5 " is an unusual way of writing 2015 or 15 that I am not aware of [emoji6]

[TFM]

That's expected. There are versions of DATE.COM including the year 2K patch. I can upload this later on from my own Laptop.


Oh, my CP/M ROMs do contain the Y2K bugfree version IIRC. Let me check later...
EDIT: No, they don't .. yet... but I fix that. (Problem: The ROM CP/M Plus uses an internal DATE command, so how to override that? We'll see ... ).

[Bryce]

Aaaaarrrrgggghhh! The Y2K bug has finally got us! 15 years later.

Bryce.

[TFM]

And here is the fix: (see attachment)


Please use all the new programs, especially when using date stamping. Enjoy! 

[CraigsBar]

Thanks. Perfect.

[TFM]

My pleasure. 

[dxs]

Thanks TFM for your help, as usual!

Thanks for your thanks! 


fun mode on...
But don't like me posting CP/M stuff, move that like over to my FutureOS source code sniplet!
fun mode off...


Well you did a great job with the RTC. Actually it THE ONLY ONE currently available somehow (maybe one day Dr. Zed will make a new batch of SF2's though). So it's of course the communities duty to support you. 

[dxs]

Yeah well don't forget only 20 were made,  not to mention some people bought more than one 

[TFM]

TBH... I have hope that you make a 2nd batch.     

[Prodatron]

The Dobbertin Smart Watch is now supported in SymbOS, including autodetection
[attach=2]
[attach=3]
It will be included in the next Beta version, which will be available for download probably end of September or beginning of October.
Thanks again to Poliander, CraigsBar and TotO for the donation and of course to  DXS for this nice piece of hardware!!

[TFM]

Ah, good to see this thread coming up agian.    Now I got my CPC working again in the USA and I had time to verify the TIMEROM#.COM I posted here before, it does work find. I also included it in the CP/M Plus ROMs collection I made (see download on my homepage),


The RTC behaves excellent, and at least as well as the original. 

[CraigsBar]

Awesome news. I did see yesterday that the rtc rom corrupts fw3.15 mode 2 startup screen, and that it breaks the hxc v3 app from either autoboot hfe or rom. Will test further and confirm later.

The documentation of the RTC stated that it's important to put the jumpers from int to ext when using an x-MEM. In this case you put the TimeROM in one 16 KB slot of the X-MEM. If there are problems, please describe the hardware configuration you're using. I got no problems here, but my setup will be different.

Yes I know that. It makes no difference if the rom is internal or external. See screenshots linked below.

I'd be interested in a next batch

For FW 3.15 thsi was expected, because it suppresses the sign on message. Therefore the TimeROM can't show you the graphic clock symbol, nor time, nor date. Clearly a FW3.15 problem.


About the HxC ROM... it's buggy anyway! I have the HxC as B drive and it always tries to fuck up my A drive by moving the head to track 255, that really suxx. The solution I found it to start the HxC tool from the autoboot.hfe file on drive B.


Sorry, for not being able to help more, but in this case the problems are somewhat in the cases nature. And there is no source for the HxC ROM out there (or I just don't know about it. Else a fix would be doable).

It is a feature... 
With 30 ROM, that avoid messages scrolling the screens, making things impossible to read and taking close to 5 seconds to get READY! 

I should update the X-MEM Install for asking about a QUIET or VERBOSE Firmware 3.15...
By the way, you can replace "CD 57 BB" by "CD 54 BB" for that. (offset $264E)

I understand why the date and time don't show, and to be honest I prefer it quiet.... BUT with it quiet why does the clock face creep in. that was more the question.

As told, it is GFX not character. 


@TotO : A verbose / quiet mode selection would be nice. But even nicer would be the selection of MODE 1 / 2.

Hmmmm. But the symbos logo is also a graphic not characters and that is suppressed. Also, on the rtc rom, only the clock graphic is shown, and not the calendar one. Sorry, I don't buy your answer

Then ask somebody else. Or look into the source code.
