ZXPand+ serial communications other than 38400?
ZXPand+ serial communications other than 38400?
When I get my new ZXPand+ I was thinking of interfacing the TTL serial connections to an old Parallax LCD display I have. However, I noticed the LCD has set switches for 2400, 9600 and 19200 baud rates.
Is it possible to use the ZXPand+ with one of these baud rates like 19200?

Absolutely. Features arrive as required - I was planning on setting the baud rate on the appropriate command.
I'll look into this for you.

Excellent! Thanks Charlie. Looking forward to seeing this usage in the next wiki manual version update also.
Quite impressive updates over the ZXPand Classic. Now...I have to look for an IDC10 cable I have somewhere and breakout into a solderless breadboard. I would also like to play with the Joystick function too. Any example coding using the bits and INKEY$ as stated in the manual? Nice features to demo at the festival in September.
Thanks again!

How to use the joystick has been talked about before. I can't remember which thread, so try searching for "joystick" on this forum

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

Charlie,
I have these items coming to interface to the ZXPand+ IDC 10 connector:
(Gravitech)
DB9 Male Breakout Board DB9M-TERM 1 7.99
10-PIN Male Header 10MH-TERM 1 6.99
Breakout Board
(Adafruit)
1 x 10-pin IDC Socket Rainbow Breakout Cable[ID:1199] = $3.95
1 x 10-pin Socket/Socket IDC cable - 6"[ID:370] = $2.00
1 x 10-pin 2x5 Socket-Socket 1.27mm IDC (SWD) Cable - 150mm long[ID:1675] =
$2.95
I hope to interface to the ZXPand+ to display Atari/C64 type Joystick information and other info as a test to a Parallax LCD serial display (Bauds 2400, 9600, 19200). Do you think the serial command will be updated soon to support other bauds besides 38400?
I tracked my ZXPand+ to New York City and then hopefully to Chicago, Illinois area next.
Thanks - Tim

I have updated the firmware to include baud rate setting! I haven't updated the documentation yet but I probably will have before your board arrives.
tl;dr: ZXPAND "OPE SER [baud]"
baud may be anything from 2400 to 38400. I could go faster with a further update to the code but I thought I'd see how we get on with this
You will want to update your firmware soon after arrival. It's a trivial process described in the docs. V >= 1.08 has the baud rate code fitted.

Re: ZXPand+ serial communications other than 38400?
That's a good range of adapter cables you got - they should just about do anything you could need to do. You've seen the pin-out information in the documentation yes? If you think it could be improved any please speak up - I'm so used to the subject that I might lose sight of what is important or omit details that I forget because I think they're obvious.
I can't wait to see what emerges here!
