Internal Refrence on teensy 4.1

[mattiekempen]

Hello,

I am using an teensy 4.1 ADC for an audio project.
I have my mic set up for 1.2 volt inputand I can't find a way to set the ADC refrence to 1.2v.
What command and values should i use for this?

Thanks!

edit:

SOLVED! found the answer on the prjc site as expected.
i need to keep in mind the audio tool is mostly written around teensy 3.*.
fixed the circuit and everything is working fine around 3.3V

According to https://www.pjrc.com/store/teensy41.html

"The analog input range is fixed at 0 to 3.3V. On Teensy 4.1, the analogReference() function has no effect. The analog pins are not 5V tolerant. Do not drive any analog pin higher than 3.3 volts."
