Hi. There is some way to clear the XRAM at startup. Like the internal SRAM that is initialized to 0 ?
Best regards. |

Hi, as know there are some problems with GLCD library and extended port (PORT E/F/G ...ecc) of ATmega128/256. Do you have a modified library to get it working ? I'm not a ASM expert.
Many thanks in ... |

Hi, thanks for the suggestion, but I use HDD, or CF in HDD mode. I think that the problems are with memory usage or memory allocation.
Best Regards. |

Hi, the internal port circuit is the same with all models ? Maybe that the new chips can't source the same current that old atmega128. Or maybe that have a different output voltage non fully compatibl ... |

Hi, the ATmega1281 and ATmega2561 are pinout compatible with ATmega128, and you could use STK500+STK501 to program these chips. (I have made all tests with STK500+501). I have bought the bord from DIG ... |
