Instrumentino for GreenHouse Monitor

First Connection

• go to Controlino program find baudrate #define SERIAL0_BAUD 115200

• go to SmartTerminal parameters.py and define a new mode Controlino:
  • self.mode = "Controlino" # this is not really needed but this way it is easy to turn on and off the Controlino settings.
  • find self.baudrate and add at end of baud rate section

    if self.mode == "Controlino": 
        self.baudrate          =       19200

this way of setting it will only be in effect for the mode Controlino which for now we will implement as a straight terminal

Install Controlino on your arduino and fire up both the SmartTerminal and the arduino. Open the port and send "set" responds with "done", the egale has landed.

Add strings for commands to interface

• look at the bottom of the C program and extract the following commands: "Set", "Controlino", "BlinkPin", "Read", "Write", "SetPwmFreq"
• find the section that looks something like:

    elif self.mode == "MotorDriver":
        self.send_ctrls = [ ...

and add a clause to the if then like:

    elif self.mode == "Controlino":
        self.send_ctrls = [ "Set", "Controlino", "BlinkPin", "Read", "Write", "SetPwmFreq" ]

Run the Smarterminal again, this time you will find the above commands loaded into the first several send areas as defaults. Try them out, all but "Controlino" respond with done. Invalid commands also seem to get no response. These commands look like they are supposed to have numbers appened as well, it would be nice if we had some values in place just to let you know what the expected form is.

Try Blink

• Blink using BlinkPin looks like it might be easy to use and test so lets look at it.
• the command seems to link to cmdBlinkPin(argV) and searching on it we find

void cmdBlinkPin(char **argV) {
	blinkingPin = strtol(argV[1], NULL, 10);
	blinkingDelayMs = strtol(argV[2], NULL, 10);

	pinMode(blinkingPin, OUTPUT);
	blinkLastChangeMs = millis();
	startBlinking = true;

This in turns suggests the command BlinkPin 5 300 will blink pin 5 with a delay ( half period or full period ) of 300 ms. Looking at my board it is very easy to put in a led on pin 7 so lets try BlinkPin 7 300 as a command.

Back to

elif self.mode == "Controlino":
        self.send_ctrls = [ "Set", "Controlino", "BlinkPin", "Read", "Write", "SetPwmFreq" ]

lets change it to

elif self.mode == "Controlino":
        self.send_ctrls = [ "Set", "Controlino", "BlinkPin 7 300", "Read", "Write", "SetPwmFreq" ]
