FYI, according to engineers at an ATMEL seminar Tuesday, the quoted write cycle endurances of Flash memory in the current AVR parts (in particular, the ATMega169 was being discussed but the BX-24p's ATMega8535 is included) of 10,000 cycles, and 100,000 cycles for EEPROM, are very conservative. Typical endurance for Flash is 100,000 cycles and even one mill

Has anyone got more info on the updated BX-24? It seems to be vaporware. While it seems not to be available yet, does anyone have an idea of what the hardware will be? Will it be the same think with more EEPROM (64K?)? Or will it have a new core too? It seems as if the Atmel CPUs share a common programming, so It would _seem_ (but what do I kno

Sometimes my code just doesn't want to cooperate. When all else seems fine i just cannot halt or download the bx. I then do the test program from bx and everything is fine.

I was wondering if there was a hardware expansion for the RAM on the LCDX. It does not need to be fast. I will be writing to it constantly in my application, so I do not want to use the EEPROM to store these variables. I would like at least a few K of RAM, but anything more than 400 bytes would be welcome. Thanks, Jer
