Unleashed 1.1.3 Open Peripherals

[KingTriaxx]

I'm wondering if anyone can help. I'm trying to build a computer/monitor set up to display the current temperature of a Steam Boiler, and I know that OpenP Should be able to do this, but I'm not sure how I figure out what I need to read off the boiler. Anyone more experienced know what I need?

Computer has it's back to the boiler and a monitor on the left (two wide, one high). Thanks for any help.

To wrap the boiler:

boiler = peripheral.wrap("back")

To wrap the monitor:

monitor = peripheral.wrap("left")

To get the boiler temperature:

temperature = boiler.getTemperature()

To print the temperature on you're screen:

monitor.setCursorPos(1,1)
monitor.write(temperature)

Those are the basic functions you need for you're program.
Go and try it out =)

Everything works except boiler.getTemperature() it returns Attempt to call nil.

Also, thanks for the help.

Did you put it next to the firebox?
The getTemperature method only works for the firebox.

Maybe post your code so I can see what's wrong.

 

[KingTriaxx]

No, I had it set up against the tank. Thanks for that.

Other than restarting, how do I make it update the temp every minute or so?

 

[angelnc]

Make a loop.

It's already a While loop. Should it update when the temp changes then?

 

[angelnc]

Show me the code and I can tell you what you have to change.

 

[KingTriaxx]

boiler = peripheral.wrap("back")
monitor = peripheral.wrap("left")
 
while true do
temperature = boiler.getTemperature()
 
monitor.setCursorPosition(1,1)
monitor.write("Temp")
monitor.setCursorPosition(1,2)
monitor.write(temperature)
sleep(1)
end

Which shows the temperature, but doesn't seem to update.

Something like this should work for you. Keep in mind I haven't tested this.

boilderSide = "back" # change this
monSide = "left"
 
boiler = peripheral.wrap(boilerSide)
monitor = peripheral.wrap(monSide)
 
function writeTemp()
  monitor.clear()
  monitor.setCursorPos(1,1)
  monitor.write("Tempature is")
  monitor.setCursorPos(1,2)
  temp = boiler.getTemperature()
  monitor.write(temp)
end
 
while true do
  writeTemp()
  sleep(60)
end

Giving me a call nil on line eight. Not sure what's wrong.

Giving me a call nil on line eight. Not sure what's wrong.

Do you have the monitor connected to the left side?

 

[KingTriaxx]

I did, then had to break it to get to the computer to break it because I couldn't terminate the program. It's working now, Thanks guys!

 

[angelnc]

To terminate a program hold Ctrl + T.

 

[KingTriaxx]

I tried that, but for some reason it was not responding the way it should. So I had to break it to get it to listen to the command.
