arduino and fpp

[andrewm659]

Here is the sketch from LSPi

The sketch you copied in doesn't look like it is doing any interaction with LSPi. It is some generic telephone keypad simulator? It is not outputting any WS2811 protocol so it couldn't be driving your pixels.

I will double check on this today.

Let's get FPP running your pixels. Did you load up the virtual eeprom? You do this from the menu Input/Output Setup, Channel Outputs, an then the Pixel Strings tab. Click the button to install EEProm and choose PiHat.

Once installed you have you two outputs to configure with the number of pixels you are running. You only need configure whatever you have attached.

Once you have that, you can use the test function under Status/Control.

Pretty sure I loaded the virtual EEProm on the server AND remote.

Right now I have WS2811 connected to it.

Here is the global.h code.  This is probably what you were looking for...

    EEPROM.write(ee++, *p++);
  return i;
}

template <class T> int EEPROM_readAnything(int ee, T& value)
{
  byte* p = (byte*)(void*)&value;
  unsigned int i;
  for (i = 0; i < sizeof(value); i++)

Here is the global.h code.  This is probably what you were looking for...

Nope that also looks irrelevant.

Let's get FPP running your pixels. Did you load up the virtual eeprom? You do this from the menu Input/Output Setup, Channel Outputs, an then the Pixel Strings tab. Click the button to install EEProm and choose PiHat.

Once installed you have you two outputs to configure with the number of pixels you are running. You only need configure whatever you have attached.

Once you have that, you can use the test function under Status/Control.

Pretty sure I loaded the virtual EEProm on the server AND remote.

Right now I have WS2811 connected to it.

When you run a test, do you get expected results?

I'm trying!

I do not.  I will try it again later tonight...?

Hello,
It is not working.  Not sure what I'm doing wrong.

I'd suggest you hop on the xLights zoom room https://zoom.us/j/175801909?pwd=ZU1hNzM5bjJpOGZ1d1BOb1BzMUFndz09 and raise your hand. Someone can try to help you interactively. If you have a video camera you can aim at stuff it would be helpful but even without one, talking with live help desk will save you countless hours of frustration.
