First of all, please accept my apologies if my questions have already been answered before, but the search function didn't point me towards the results I am looking for.
My questions are about preferably the use of the two ADCs synchronously (one MUXed on 2 inputs, the other exclusive on 1 input) or one ADC with 3 inputs MUXed in Teensy 3.1. I found the following information on the pjrc homepage:
"Two Analog to Digital Converters
With analogRead(), you can measure many signals, but only 1 at a time. Teensy 3.1 has a second ADC, so you can concurrently measure 2 analog signals. For stereo audio or power monitoring, sampling both left and right, or voltage and current at the same moment is very beneficial.
PJRC is developing an advanced analog read function for Arduino, to make using these new analog input capabilities very easy."
Is this advanced analog read function already available? If yes, where can I find it, please?
I'd like to find simple instructions or functions to set the ADC configuration (inputs, resolution, sampling frequency, interrupt) for use in a Arduino/Teensyduino sketch, if possible without studying the whole 1400 page programming handbook. Is there perhaps a kind of tutorial somewhere on the web which explains the use of the extended functionality, compared to the Arduino standard analog read?
Thank you in advance from France
