> pata_hd_read_data() gave me about 320kbytes/s, while read_sector() gave about > 130kbyte/s. I haven't done actual speed tests, so you are more correct then me. But I also don't like calling a procedure 256 or 512 times, when read sector could be used.
One thing you must keep in mind is that SD Card uses the same port as 23k256 (spi ram), or other things the user may want. With SD Card, you must watch the chip select line, so read sector is better. Mostly because I like the usage of storing file name locations in an external ram such as 23k256. Internal PIC ram works fine too, but you are limited to the number of files per directory. do you have a 23k256? >When large_array is not used, read_sector() yields about 520kbytes/s Ok, how. Are you suggesting to use two normal arrays of 512 bytes? >Ok, time to svn up :-) I'll get my stuff up on SVN asap. >You'll regret that one ;-) all suggestions are welcome. I won't regret it. Hopefully you have lots. We can start a list of issues. Matt. -- You received this message because you are subscribed to the Google Groups "jallib" group.
