Arduino Due and simulink voltage resolution

13 views (last 30 days)
I would like to use the analog inputs on the arduino Due board for a project I am doing, but I need a voltage resolution of 12 bits and the default is 10 bits.
Is there a way to change this? either in simulink or by hard coding it in?
Thanks,
Nathanael

ok i solved the problem with a easy s-function. check out this vid and just implement it with the arduino library command "analogReadResolution(12)".

This depends on the analog-to-digital converter of your card.

Thanks Azzi,
I am using the Arduino Due board, which is capable of 12-bit ADC, however when it is initialized in simulink it is set to 10-bit ADC. Is there a way to change it from 10-bit to 12-bit within simulink?
Thanks again

have the same "problem" and would like to know if there is a way to change the input resolution of the arduino due from 10 to 12 bit. Maybe with a s-function?

Ok great I'll have to test that out.
Thank you.

Have you manage to change the resolution to 12 bits. Mind to share your achievement? thank you.
