NodeMCU for IRs?
« on: September 13, 2021, 04:43:57 AM »
There was a thread recently how to load effects into FV-1's EEPROM via WiFi using the NodeMCU so I was wondering whether it's powerful enough (in combination with a ADC/DAC board) to use it (or an ESP32 loaded one) for IR processing and loading impulses from a phone? A nice addition would be a 0.96"OLED display to show the impulse is loaded.

So if I understand you correctly, you want the NodeMCU to do the DSP processing? or you still want the FV-1 for the IRs...?
Well, in either case I think you wont have enough RAM to do anything useful (IRs are pretty memory expensive)

Not much RAM and processing power to do IR processing. But, you could try the approach of transforming the IR into a FIR.
There was a discussion around it here:

And gena_p1 created a tool to help on the translation. What could be feasible is to have the NodeMCU do this translation for you, and then load the resulting code into the FV1

You would still be limited to a 126 coefficients FIR

I didn't mean FV-1 to be used for IRs at all. From your replies it looks like the NodeMCu can't handle IR processing so my question was answered.

Ok, I misunderstood what you were trying to do. I have no clue if NodeMCU can handle IR directly.
