Wat is nodig

avr-gcc
avr-libc
avrdude

Voorbereiding broncode 0.16

Pak uit OpenDCC sources met unzip¹
Verander in Makefile avr-gcc.exe in avr-gcc
Verander regel 100 in @avr-size ${TARGET}

¹) Het zip password moet via mail opgevraagd worden, zie voetnootsonder aan de pagina of http://opendcc.de/elektronik/opendcc/download.html

Parser kiezen

Plaats de parser in de config.h

#define PARSER  INTELLIBOX  // LENZ: behave like a LI101
                            // INTELLIBOX: behave like a IBOX

Build

cd default

Alvorens OpenDCC in te schakelenmoet Stop ingedrukt en vastgehouden worden. Nu wordt een zgn. bootloader opgestart (CTRL LED brand permanent), er wordt nu op een nieuwe software versie gewacht. Deze software wordt in het niet vluchtig geheugen van de OpenDCC geladen.

avrdude -pm32 -cavr109 -P/dev/ttyUSB0 -b19200 -Uflash:w:OpenDCC.hex:a -Ueeprom:w:OpenDCC.eep:a

ATMEGA644P (linux)

avrdude -F -pm644 -cavr109 -P/dev/ttyUSB0 -b19200 -Uflash:w:OpenDCC_XP.hex:a -Ueeprom:w:OpenDCC_XP.eep:a
