Falcon Player (FPP) / Re: FPP 8.4 released!

Last post by lrhorer - Today at 11:30:42 AM

I have temporarily enabled GPIO4 to run the script both when the pin is rising and falling, and added an argument to tell whether the pin is high or low.  This works somewhat, but is far from ideal.

GPIO4 transitions low whenever power is no longer available to the string.  This implies one of two things.  Either the fuse feeding the string has blown, or main power has failed.  GPIO17 will also drop if the main power fails.  Ordinarily, I would be able to simply inspect both to see which is the case and respond appropriately in the script.  Using the value of the argument (argv[1]), I can discern the fact GPIO4 has transitioned low, but there is no way to do this outside of the instance when FPP makes the call.

To put it another way, Normally I should be able to run the script from the CLI using the alias `status_print`, which ideally should say:

Host Name: Lighting1
CPU Temperature: 49C
CPU Usage: 3%
Disk Usage: 23%
Memory Usage: 47%
Power OK.
Fuse Failure!
Case Temperature 44.9C
Battery Voltage 11.43 Volts
Fan On
Cooling Off

but the script is unable to make that determination except when it is called by FPP because of a failure.  Instead, all it can do is say:

Host Name: Lighting1
CPU Temperature: 49C
CPU Usage: 3%
Disk Usage: 23%
Memory Usage: 47%
Power OK.
Fuse Status: Unknown
Case Temperature 44.9C
Battery Voltage 11.43 Volts
Fan On
Cooling Off

Falcon PiCap / Swapped PiCap V1 with V2 - Pix...

Last post by twseeman - Today at 10:24:13 AM

I purchased PiCap V2 to take advantage of 4 ports.  PiCap V1 was working with my leaping arches.  I also upgraded to FPP 8.4.  I am running on a Raspberry Pi 3a.  When I attempt to test pixels, I get not lights.  I will include a screenshot of FPP and the PiCap V2.  I don't know if there is a manual, if there is, can someone point me to it.  I just need help determining while the pixels don't light.
Thanks

Does the Falcon PiCap v2 support Renard output?  The product page does not specifically say is why I'm asking.

Falcon PiCap / K2-Pi-Servo

Last post by breese - January 17, 2025, 01:47:06 PM

@dkulp
I received my complete K2-Pi-Servo package.
After configuring it I updated it to 8.4.2
When I go into Channel Outputs / Servos Tab and Activate the hat, when I click on Save it highlights but never saves.
If I active the servo hat, change to the Pixel Strings, activate the Enable K2-Pi-Servo, and click Save, Both settings are updated.
Edit: The saved settings for the Servos do not stay activated after a reboot

Falcon Player (FPP) / Re: FPP 8.4 released!

Last post by lrhorer - January 17, 2025, 09:09:58 AM

I was unfamiliar with node-red, so I looked it up.  It is just about the last thing on Earth I would want to use for this application.  I could, of course, use an external watchdog to keep track of the GPIO pins, but why add extra code if the code to handle the transition is already in FPP?  I could also take a brute force approach and spawn an external instance of `gpioinfo | grep GPIO4 | grep low`, but that is quite brittle and rather klunky.  An internal Python routine would be far more future proof and independent of the vagaries of gpioinfo.[

Edit: gpioinfo does not work as expected.  It only reports whether the pin is used and whether it is active low or high.  It does not report the actual pin state.

The script does not interact with FPP in any way.  It runs under various situations, one of which is a power or fuse failure, which is indicated by GPIO4 transitioning from around 3V to 0V.  After the script is spawned, it collects various data such as CPU usage, memory usage, temperature, etc.  If requested by the name used to call the script, or if an important situation exists it sends emails and / or texts.  Otherwise it responds per the name used to call the script.

If both GPIO4 and GPIO17 are low, then there is a main power or main fuse failure.  If only GPIO4 is low, then it is a failure of the fuse feeding the string.  If neither are low, then power is OK. (Obviously in this latter case, the script was not called by FPP.) Here is the script so far:

Falcon Player (FPP) / Re: FPP 8.4 released!

Last post by darylc - January 15, 2025, 07:24:07 PM

FPP is indeed using the pin, as expected.  The problem is, I still need to be able to scan the state of the pin in the external script.  The script needs to run on the falling edge of the pin, but it also needs to examine the pin whether nor not it has been called by FPP.  It runs under various situations, including when FPP calls it, as well, and it needs to know the status of the pin whether it has been called by FPP or not.

Personally, I would use node-red instead of a script and have FPP issue a MQTT status when the pin is pressed and let node-red do all the logic including calling back to FPP's API to cause FPP to do things.  This comes with the added bonus of a visual workflow rather than having to re-read/learn the script each time to troubleshoot or modify it.

The overlay model is probably not enabled.  Either use the AutoEnable above set to true or you can use the /api/overlays/model/:ModelName/state endpoint to enable the model in a separate call.
