I wrote a series of articles on an Arduino Handheld Prototyper and part of that was for an I2C MiniTerminal that used a small LCD screen for output. You can find information on this at: http://blog.smileymicros.com/ You can get started at: http://blog.smileymicros.com/arduino-handheld-prototyper-par...

I'm not familiar with that specific device, however it does seem to have a lot of pins for an Arduino. I Googled 'HDSP-2531 arduino' and got a few hits, but this doesn't seem to be a commonly Arduino'd device.

I commented out the reversing code in lab 3! In lab 3 I have: //val = 180 - val; myservo.write(val); // use converted angle Remove the // so that it reads: val = 180 - val; myservo.write(val); // use converted angle As far as a nice project - how about that servo tester you mentioned? Wouldn't that ...

Its probably related to the delay() function or possibly your computer is running other processes in the background?

Which program runs slow and which fast?

Did you copy this directly from the source code or did you input the code yourself?
If you input it yourself, could you post it here so I can have a look?

Well that is puzzling. The code: volatileuint16_t** ** Isn't in my stuff so it is probably something from the Servo library that isn't being used properly somewhere deep under the hood. Maybe you can get an earlier version of the Arduino IDE like 1.0.1 and see if it runs on that? I know this is frus...

This indicates that there is a problem with the servo library, not the program I've shown. That likely means that the servo library has not been installed properly or there is some sort of change in the way it is used between Arduino IDE editions. I'm using 1.0.5 so if you are using an earlier versi...

I suspect this is typo? I just copied and pasted the file into Arduino and it compiled okay. One problem is that I didn't submit the correct zip file to Nuts&Volts for this code. I just resubmitted it so it should be attached to the article in the next day or so. In the meantime try the followin...

Frank,

Sorry I didn't get back on this. I couldn't duplicate the problem decided to give it a rest and then plumb forgot to get back to it. Glad you finally got it working.

There could be any number of reasons for this problem and since I don't have experience with GPS modules I can't help with this other than to suggest Googling the brand name of the GPS unit along with the word 'Arduino'.

Frank,

I'm sorry you are having an issue with the code. I'll look at it later this afternoon and see what I can figure out.

John, Well something happened to the application program on the I2C Mini Terminal. I tested your circuit with a known good ATmega328 with the correct program and it worked so you didn't do anything wrong with the construction. Interestingly, I test all the chips before marking them, but for some rea...

Well I'm pretty clueless about doing this with an AVR and I'd be more likely to approach this with a Raspberry Pi. I know that Sparkfun and AdaFruit have GPS modules and some tutorials - that might be a good place to look.

Well, I'd reheat all the solder joints, especially on the ATmega328 socket and the LED headers and see if that fixes it. Since you are getting the serial monitor feedback then most of the joints are okay. I really can't think of any other cause for the problem, but I'd be happy to take a look at the...
