bootloading the arduino to run at 3.3v
The trick to running the atmega328 at 3.3v and not 5v is to load a new ‘bootloader’ on it. The chip I purchased came on top of an Arduino Duemilanove. As such, it was pre-programmed (which is what the ‘bootloader’ code does) to run at 5v. (For more on ‘bootloaders’ and arduinos see here.) So I basically needed to load a new ‘bootloader’ on to the chip.
ASCOM driver completed
Hmm. That took a long time. A seriously long time. Anyway, I’ve now completed the ASCOM driver – the software which sits on the PC (within a planetarium programme) and communicates with the mount. The final driver (sitting within SkyMap Pro) looks like this: (I should add that the “hand controller” seen in the picture […]
LCD: SparkFun’s serLCD and NewSoftSerial
http://www.youtube.com/watch?v=skqVepTQMRU The video above shows SparkFun’s serLCD in action using a library (serLCD.h) which inherits all of the NewSoftSerial library functions and then adds a few of its own. The library is set out in full below (with download) but first up, my first sketch using the serLCD (which might help others get a feel […]
