Hello, Im new to Arduino and dont find an answer on the internet to the following question: is there a way to change the analog in and pwm resolution using Matlab or Simulink from standart 8 bit to 10 or 12 bit? The I/O block package in Simulink doesnt seem to support this, also the command "Analo…

you can do oversampling of the 10 bit signal. to get an extra bit you need to sample 4x as much 2 bits extra => 16x as much samples check this doc - http://www.atmel.com/Images/doc8003.pdf - you need to implement this on the Arduino and you can define your own command in MATLAB to send to serial…

Can you explain what an S function does?

it is a custom Block in the Software Matlab Simulink. With the Arduino IDE i have no problem setting the resolution of the a/d converters to 12bit. There i just use the command "analogReadResolution(12)". But for the Matlab Simulink Support package, there is no option to change resolution. therefo…

Hi , Can you share the s function you are using for changing the resolution of due analogRead and analogWrite using simulink. I would be really grateful as i am stuck in the same problem. Thanks a lot
