How to add 'Tone' on digital pin of Arduino Uno?

Hi,

I am having an issue with the function PlayTone and my Arduino Uno.

I am using Matlab 2018b.

I am trying to configure a Digital Pin on my arduino uno with the specificity "Tone".

However whenever I try it, I get the following answer:

configurePin(a,'D7','Tone')

Invalid digital pin mode. The mode must be a character vector or string. Valid mode

values are:

DigitalInput, DigitalOutput, Pullup, PWM, Servo, SPI, Interrupt, Unset

Whenever I try to use the function Playtone (on D7) I get:

playTone(a,'D7',4000,5)

Invalid pin number. Valid PWM pin numbers for board Uno are D3, D5, D6, D9, D10, D11.

However, all the valid PWM pin numbers are taken by the servo that I am using.

Please let me know if you have a solution, I am pulling my hair out here..

Thanks,

Renaud

Tone was not supported until R2019a... the version immediately after the one you are using.
