We have been using Teensey + Arduino in designing a IIOT product for our customer. The deployment time is near, and we have just come across a problem around Analog design we had. We can overcome that if we can have Amplifier and Bandpass Filter acting within Teensey through the software library. We have seen the tutorial and also tried through Audio GUI web tool of Teensey, but not able to map against our need.
Technical Problem Statement - 1:
We are using Teensey-3.6. We will be having Input Analog Signal coming to the A22 pin of Teensey. The Amplitude of signal is going to be vary, and we are deriving a resistance of a field instrument out of this. Right now with increasing value of resistance we see much lower amplitude and values are also adjacent – ADC count has minor variation, and it makes us unable to distinguish the resistance of a field instrument.
Solution Needed:
If we can have a Amplification block internal to Teensey, which can be introduced before we read the ADC resolution in software then we are seeing a hope here.
Technical Problem Statement - 2:
Adding further to the problem statement-1, the signal is going to come from field so there would be high chances for noise in the signal. We don’t have a scope lately to have a filter in the hardware board to overcome this.
Solution Needed:
On the same ADC input, if we can have a bandpass filter block internal to Teensey, which can be introduced before we read the ADC resolution in software then we are seeing a hope here.
Please help us with the problem statements mentioned above, and it would be great if you can same further reference or code-snippets which can help us to move forward.
