I've been building Gameduino2 code for the Goldilocks 1284p platform. Although I've got a range of Arduino compatible boards, I've found the Goldilocks is the best platform to use. Some of the major reasons are noted below: - The ATmega1284p MCU has 16kB of RAM and 128kB of flash which means that (for example) all of the FTDI API options can be enabled simultaneously. With an Uno you are limited to at most 1 of 4 options.
- Most importantly, Goldilocks supports the Pre-R3 Uno SPI pins, which the Gameduino2 needs. Because the LCD screen connector attached to the back of the Gameduino2 wrap around the end of the shield, it was not possible to implement the SPI ICSP. This means that to get adequate RAM and flash for significant applications, you have to hack a Mega or Due to bring the SPI interface to the traditional Uno SPI location. Supporting traditional SPI pins means Gameduino2 works on Goldilocks without any hacking or soldering.
- Goldilocks supports 20MHz or 22MHz system clock, so the SPI bus (for downloading commands to the Gameduino2) and your GL command rate is running 25% faster than with a normal Arduino.
- Integrated 32kHz watch crystal, to keep real time using avr-libc time.h functions, leads to a touch screen clock...
There is a Google+ Community for Goldilocks. Thank you for pledging on the Kickstarter Project. Closed on November 19th 2015, with 124% funding. Now that the Kickstarter Pledges have been shipped, the Goldilocks Analogue is available on Tindie.
