I just tried VGA and I am not getting anything displayed. PC is working with your code.
I will need to check my wiring but not tonight
VGA and Brian's LA work as I tried it already. This is my setup:
P0-->HSYNC
P1-->BLUE
P2-->GREEN
P3-->RED
P4-->VSYNC
Just wire up the grounds and connect to these pins directly and it will work, especially as Brian's code runs on a P2D2 like yours.
Yes, that is how I thought I had wired it. GND is just above the P0/P1 pair.
If the cable meters ok, I'll try another monitor. I am using an Acer X233H 23". Perhaps it's not recognising the auto switch (might require 3V3/5V on the power pin 9)
Brian,
I've just run up P123_A9_LA.exe on Wine and it gives me a baudrate error, see attached, that seems at odds with experience. Or at least Linux programs don't have the same restriction. I guess Wine might be filtering the setting.
Is that due to a query in your code? If so, I'd like to try a hack where it just specifies the desired rate and hoping it works.
Oh, just found the later zip file with P2_LA_control_3.exe in it. That's happy with comport as long as I use 115200 baud. I'll assume that's a usable rate ...
For P123-A9 board you need to change back to a single HUBSET #$FF and change VSYNC to 0 from 4.
That should do it, I'll check it tomorrow.
The P123-A9 will support 3 MBaud.
BTW I run the Logic Analyzer with a FT2232H as a propplug @ 12Mbaud.
I want to switch to 50Mbaud sync mode next to get a real snappy frame rate.
Got past that hurdle - I loaded the .obj file as BOOT_P2.BIX onto a uSD card and used the experimental SD boot wiring to auto load up on reset.
Sadly clicking on RUN or INFO produced no display. Wine is reporting a slow stream of "004f:fixme:comm:wait_on EV_RXFLAG not handled" messages when doing so.
Here's a test code sample of exercising a smart pin in transition mode.
It include the use of a pins selector capability to read an nearby pins state.
Also the use of a marker signal.
Got a match here using Wine and also inserting backslash into all LOC instructions:
PS: I think it was always working with Wine - with nerf'd comport function. I just wasn't giving the upload enough time to complete at 115k baud. I kept on clicking buttons because it didn't show any progress.
Dave had to resort to using a cross-platform library, I think, to make >115k work transparently for his loadp2 tool ...
EDIT: Sort of. Looks like a bunch of people involved to get that right. Dave Hein has used osint_*.c files that have been updated by David Betz but appear to be originally written by a John Denson.

Presume its monochrome?
Comment out monochrome palette and uncomment color palette.

EDIT: Except I've only got a P123 board.
I used 1M baud. You have to open the com port on the pc, then click the RUN? button.
That should do it, I'll check it tomorrow.

Loading up the LA_Control program on Wine and click Open Port and bam, the FPGA Prop2 resets.
Clicking RUN and I see Tx led flicker. But, since the Prop2 is now sitting idle, there is no reply.

Think I'll be leaving it there.
