This is for an interactive installation. I'm using an Arduino to have a monetary button send a bang to Max. I'll have the patch autorun on startup of the computer.

I'm trying to [loadbang] 1)Pin 2 2)Digital-Analog In 3)Toggle poll on...

When I do this. It doesn't work unless I manually select from the [unmenu] what I want using the mouse. Any ideas or solutions to this?

This is something probably very simple that I'm just not getting.

if the items from the umenu are never changed, why not ditch them and just loadbang the message (2, 0) in the [pak] object. Remember to use the [trigger] object after loadbang, to chronologically order your messages!

Hi

Thanks for the suggestion. I made those changes but still experiencing the same problem.

I have an arduino connected and using a simple monetary push button.

When I launch the patch and press the push button nothing happens. It's only when I click the loadbang or the 0 and 2 message objects with the mouse, then pressing the push button I see the Pin2_Digiln toggle button turn on.

The protocol for communicating with this sketch is:

- When setting a pin state you can write 0 (input),1 (output),2 (pwm)

- Example: [p 3 2] & [v 3 128] == Pin 3 is set to be pwm and addressed with 50/50 duty cycle (medium "speed")

(just send as char values from any program that can communicate with serial ports ex. Max/MSP)

- You´ll need "[" and "]" to start and end requests.

- Example: 7 0 == Pin 7 is set to receive a digital input (a carriage return is send to end request.)

- The board will only output through serial if an Arduino port is set to input.

int portregister[]={1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};

if(explodedSample[0].equalsIgnoreCase("v")){

setPinValue(convertStringToInt(explodedSample[1]),convertStringToInt(explodedSample[2]));

else if(explodedSample[0].equalsIgnoreCase("p")){

setPinState(convertStringToInt(explodedSample[1]),convertStringToInt(explodedSample[2]));

Hi Brendan,

SERIAL INPUT:
  - set pin state (p) og set pin value (v)
    - When setting a pin state you can write 0 (input),1 (output),2 (pwm)
  - set pin number
  - set value
  - Example: [p 3 2] & [v 3 128] == Pin 3 is set to be pwm and addressed with 50/50 duty cycle (medium "speed")

SERIAL OUTPUT:

  - value

I don't have (or want :p) the ArduinoInOut stuff, so I'm just guessing here but; if the Arduino is expecting a call-and-response (while and if conditions above), then it appears that your button press is what kicks off the process. A lazy guess would be to try and send the char "[", as stated at the head of the code above:

– Example: [p 3 2] & [v 3 128] == Pin 3 is set to be pwm and addressed with 50/50 duty cycle (medium “speed”)

You´ll need “[" and "]” to start and end requests.

Sorry not to be more help, but I'm crap at troubleshooting these prefabs, I prefer to roll my own code and patches for Arduino stuff.
