Maestro voice control code

justinwhite3 · February 29, 2020, 8:13am

Hi there.
I need some real 101 help here. I would like to set up a geeetech voice control module to simply start and stop my script. I have no idea where to start. The examples I have read just confused me as I fundamentally do not understand what code needs to be sent and what code needs to be received and how that code needs to be written. Below is all the info I have gone through. Any help from anyone would be greatly appreciated.

After setting up the geeetech voice control module ( check out link 1 and link 3)
I need to program the Pololu maestro to send a hex code to start and run script so that the voice control module boots up. As you can see the arduino code example in link 2
Then like before I need the code on the pololu maestro to wait for either the button push or hex code from the voice control module to then run the rest of the script. .
Under is the script I’m trying to write but I know its all kinds of messed up.
I know I’m asking a lot here so I appreciate any help I can get.
thank you all
Justin

Hello.

A Maestro script can be used to send serial bytes, but it cannot be used to process incoming serial bytes.

If you can set up your system to send the Maestro a specific command when it is ready, you might be able to make it work by using one of the “Serial Script Commands”, such as “Restart Script at Subroutine”. Alternatively, if your voice recognition module can output a digital high or low signal when it is ready, you could use a Maestro channel configured as an input to monitor that as if it were a button or switch.

I am not very familiar with that Geetech Voice Recognition Module, but from skimming through the manual you posted, it does not look like either of those would be an option for you.

If you want to process the serial data returned from the voice recognition module, you might need to add a separate microcontroller such as an Arduino or one of our A-Star programable controllers.
