Filtering analog input

X_G

Hi,
I'm sending an analog input to the analog input module, and I want to filter it (low pass, the signal is noisy) online to move to the next state once it reaches the threshold.
Is there a way to filter it online without using bonsai or Arduino?

Thanks!

Josh

Hello X_G,

The analog input module firmware already has a lot to accomplish during each sample. There is some room for additional code, but DSP functions can be costly in terms of processing, and I'd definitely recommend thorough testing of all functions before using DSP-modded firmware.
The easier thing might be to build a physical low-pass filter. An RC filter is easiest - passive, and only requires 2 components. You can also get fancy (e.g. this).
