Well, I'm particularly fond of the MegaDonkey from mega-donkey.com It does everything I want a microcontroller to do (it should, I designed it). Atmel ATMEGA2561, 256K flash, 8K RAM, LCD 160x80 graphics touchscreen display, two serial ports, IIC ports, A/D ports, lots of I/O pins, beeper, prototyping area, wonderful open-source software, makes Julianne fries, gives a fair backrub. The softwware is in avr-gcc so you have a full blown C compiler. There is also a version with a Mega128 chip (128K flash,4K RAM, 128x64 LCD, mediocre backrubs) and one without the LCD.
The software has a software time-of-day clock with crystal freq calibration capability. Has demo routines for digital and analog clock displays. Internally it runs off a 10 KHz interrupt so you can get that level of resolution. You could add a battery backed IIC clock chip (we have a couple of circuit boards floating around, haven't written the software yet). Also there is a 8 pin SOIC chip pad area in the prototyping area where a clock chip could be added). ---------------------------------------- _________________________________________________________________ Reveal your inner athlete and share it with friends on Windows Live. http://revealyourinnerathlete.windowslive.com?locale=en-us&ocid=TXT_TAGLM_WLYIA_whichathlete_us _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
