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.
