Re: Teensy not working when plugged into JackAl board
I rather see you using a PS with enough power for the board. The USB connector will supply the voltage for the Teensy. Jack, W8TEE

Hi Jack, thanks for the quick response.? The two thick wires in the photo are bringing 12v to the board.? The two switching supplies also use that 12v to generate the 3.3 and 5 volts that would normally come from the onboard regulators.? Another poster hooked it up this way (see post /g/JackAl/message/1112), so I figured this would work.?? The 12v comes from a Heathkit 0.5 amp supply.? I know that's not enough current for the display (I'll be using a 12v battery when I get to that point), but it should be enough for the Teensy. -- Chuck WB6GPO |

I found that if I bypass the buck converter and put 5V directly on the JackAl, then the Teensy works.? So time to put the regulators on the board.? On to the next dumb mistake!? Thanks. -- Chuck WB6GPO |

Re: Teensy not working when plugged into JackAl board
What happens if you connect 12V to the power jack? Jack, W8TEE

Re: New to Arduino
If you ever need a pin out image, go to your Internet browser and type in the search, like? ??? ATMega2560 pinout When the browser returns, right below the search dialog box you will see: "All?? Images?? Shopping....." Click on the Images option and you will be presented with a bunch of pinout images. Jack, W8TEE

Re: New to Arduino
No, this says the relay is to be attached to pin 22. The code simply turns the relay on and off for 10 seconds. Read the reviews and then get a copy of Beginning C for Arduino, 2nd Ed from Amazon. You'll have fun with it. Jack, W8TEE

A couple of things. First, do you know what Arduino graphics library your display uses? Second, pin 13 on the Arduino family of controllers is usually tied to the onboard LED as seen in the example Blink sketch. That is a general purpose I/O pin. Therefore, it would seem to me that you should be able to use any of the Mega's general purpose I/O pins for whatever you want to connect to it. Obviously, you'll need to change the code so it looks for the new pin number instead of pin 13. Just be sure that any device you connect to an I/O pin doesn't carry more than 5V or draw much over 35mA. Also, save the analog pins for other uses and use the digital I/O pins. Jack, W8TEE

OK now that you know what the board looks like how to I connect a output that works on pin 13 and two inputs that also work on pin 13 so I can use them with the setup I have .? I tested the outputs and inputs on other pins and they worked there also.? With all the other pins exposed can I use them in place of pin 13?? If so how? John Galway KH6JTE PS.? It was you AA that I built got this bug into me.
