Introduced very lightweight pfs implementation based on Apple ProDOS. ProDOS requires for each opened file a user-supplied page-aligned 1024 byte i/o buffer. This makes the generic POSIX file i/o library contained in the cc65 C-library quite heavyweight. In contrast the lightweight pfs implementation uses the uIP packet buffer as ProDOS i/o buffer. Therefore: - Only one file may be open at any time. - That file may not be open while the uIP packet buffer is used by uIP. The open()/read()/close() sequence should be completed before Contiki event scheduling or inside handling a single Contiki event. - The uIP packet buffer must be large enough to hold the ProDOS I/O buffer. Depending on the position of the uIP buffer in memory this means between 1024 and 1024 + 256 bytes. Therefore in an Ethernet environment setting the MTU_SIZE to at least 1266 is safe (So the default of 1500 is just fine). 2008-01-01 19:49:50 +01:00			`CONTIKI_SOURCEFILES += log-asm.S pfs.S`
Introduced very lightweight log implementation not depending on any file I/O library. 2007-12-21 01:43:57 +01:00
Starting with the cc65-snapshot-2.11.9.20080316 the Apple2 C-library supports placing code in the Apple2 Language Card by choosing the code segment 'HIGHCODE'. By default the memory area 0xD400 - 0xE000 is used for HIGHCODE. If the application doesn't need the ProDOS 8 QUIT code then the memory area used for HIGHCODE may be extended to 0xD000 - 0xE000. Contiki now leverages that feature to place process.o, etimer.o and uip_arp.o in HIGHCODE. These files were carefully chosen as: - they are necessary for all Ethernet apps - their size doesn't depend on configuration macros - they fill the available space nicely (with a little reserve for changes in the source or the compiler) 2008-03-24 23:49:00 +01:00			`HIGHCODE_SOURCEFILES = process.c etimer.c uip_arp.c`
