Arduino Library functions generate error on lua script

[ZioZanna]

Good morning

I did follow the wiki on https://siminnovations.com/wiki/index.p ... #Installer in order to use hw_... library to send and receive message from arduino

No problem to compile the skecth and send it to arduino; the problem is on lua thats stops with error because the hw_... functions does not exists

here the code

function new_message(id, payload)
print("received new message with id " .. id)
end

msgprt = hw_message_port_add("ARDUINO_UNO_B", new_message)

ERROR - Error loading instrument script: logic.lua [string "logic.lua"]:15: attempt to call a nil value (global 'hw_message_port_add')

same when I call

hw_message_port_send(msgprt, 777, nil, 0)

ERROR - error in hardware button pressed callback: [string "logic.lua"]:51: attempt to call a nil value (global 'hw_message_port_send')

Any helps?

Thanks

Hello ZioZanna

could it be that the hw_message_port_add need also a port number ?

Thanks Gilles

As far as i understand don't Think that the funcs require a specific port because the library functions are referring to a dedicated Arduino as in the Wiki lua exsample

The error generated in tipical of a non declarated function.

-- This function will be called when a message is received from the Arduino.
function new_message(id, payload)
-- Do something with the message from the Arduino
end

id = hw_message_port_add("ARDUINO_MEGA2560_A", new_message)

-- Send a message to the Arduino with id 777 and 3 bytes as payload (0x01, 0x02, 0x03)
hw_message_port_send(id, 777, [ 1, 2, 3 ])

I have no more idea as i've not work this way for the moment (with a sketch)
but rather with Arduino Installer having good results for now on my own

i think the community will help better than i could for this

Best regards

What version of AM do you have? You need at least 3.1 to use those functions. It looks as though you are trying to call API functions that do not exist in your version of AM. Installing the latest beta should fix it.

Correct , upgrading to latest AM3.2 the error goes away.

Still have problems in communication between AM3.2 and ARDUINO UNO as in this new thread

many thanks for your help
