pHAT doesn't seem to communicate with ECP bus

[kd7mlg]

So ... got my pHAT in the mail today, got the header soldered on, and with both the pi I had intended to use (an older Pi B Plus) and a Pi 3 Model B, I have nothing but frustration.

I've verified all my wiring is correct. I've verified that all keypad addresses are active (for now). Using a fresh image of the official raspbian image (without any updates/upgrades so far), and I get bupkiss.

I can connect to the device over serial (assuming I shut down ser2sock first)
I can connect to the device by 'telnet localhost 10000'
I can interact with the device (it responds to it's command repertoire)
But I cannot get it to decode any ECP data.

I turned on debugging (@48) and see the following:

As best I can tell, the device has a proper configuration in it...

Code: Select all

!CONFIG>MODE=A&CONFIGBITS=ff05&ADDRESS=18&LRR=Y&COM=Y&EXP=NNNNN&REL=NNNN&MASK=ffffffff&DEDUPLICATE=N

(I've tried with the emulations both on and off. Presently the panel is not configured for them.)

My old faithful 10-year-old AD2USB interacts with the ECP bus as expected (even though the webapp and modern keypad app will not interact with the old hardware).

Thoughts? Ideas? Where to look next?

[mathewss]

Hmm. That data looks odd indeed. What is this panel model info.

It's a new out of the box Ademco Vista 20P rev 10.23.

The odd thing - to me, knowing enough about all of this to be dangerous - is that I do see a proper decode from the old AD2 but not the new pHAT.

The green blinkenlight flashes about 2.5 times every second. At one point I had found a link on the wiki that described the blinkenlight behavior but can't locate it now.

I've defaulted the panel (it came that way, supposedly! lol) and still no joy. Even doing a full power-down and power-up cycle yields nothing useful. System keypads work as intended.

[mathewss]

Could be a bad board

The debug data looks very odd for a 20p

What firmware version are you running?

Also I noted you had LRR and COM enabled. I suggest these be disabled until normal operations can be achieved.

Since you had the USB working I have no other ideas as that would have the wiring etc all good.

Send me a bigger capture.

Is anything else connected to the panel?
If so press a few keys on a keypad while logging.

Send me your order number and I will send a unit I QA tested.

I just started a putty logging session and put the panel through all the various ways to arm (away, stay, night-stay, max, instant). Here's what I've got so far... i'll let the log run overnight if you want more.

[mathewss]

Not good. I do not see any data from the DI line and the data on the DO line looks very odd.

I need to send a known good board to confirm. Send me the order # and I will ship it out first thing tomorrow.

Ya I just did a test. I get a very similar result if I don't have my DI line connected properly.

Code: Select all

!Reading configuration.
!UART init.
!Ready. Press ! for configuration.

Send me the order #

1999.

Regarding the test you did, I did verify continuity between all four terminals on the pHAT and the control and all the wiring is confirmed, so if there's something buggered up it's probably on the pHAT.

Thanks for you help.

[kd7mlg]

After sleeping on your last comment about the DI line... I just checked, and there is no continuity between the screw terminal and the solder point when the screw terminal is plugged into the header. Have any spares or a part number? That will be an easier/cheaper replacement to rule out other problems.

(If i was more confident with my ability to not completely screw something up, I'd jury rig something as a test...)

[mathewss]

Sounds like a bad mechanical part. I will send out a new board you should get it in a few days.
