i want to connect a PIC18F4450 to and sd card, but i'm wondering what speed the data will come from a card clocked at 48Mhz with a date rate of 25 MB/s.
How many nanoseconds will a high/low pulse last?
Does data on the command line get sent at the same speed?
thanks that was around the value i was thinking just wonder if anyone knew, back to the datasheet have to take a much closer look at the timing diagrams.
Once again, basic makes life easy for everyone, check out the following link for an addon in Proton+ made by Steven Wright, of course you need the full version of Proton to use it, but hey, a SD card interface with a few commands that generates FAT16 files so any PC can read them - im there
