Greetings all, i hope everyone is well...
I havn't posted here in a long time, i've not hit problems i couldn't solve till now...

First time playing with SPI, so, i may have a noob mistake...

Ok, would love to read and write files to SD using 18F46K22 @ 64MHz so since the 46K22 is 'almost' pin compatible with the 4550 i thaught i'd start with what already works befor writing my own.

I renames SDFS to SDFS16 because i have the fat32 version to which is called SDFS32... just so their was no confusion...

I'm aware the 46K22 has two hardware SPI ports, the necessary register changes have been made.

Here is my code with the include.

Code:

So, how do i have the hardware, first off i'm using plug board...
Two SD cards are old ones, i plugged them into my PC and formatted them to FAT16 before i soldered on some sip pins. (stop cringing)
Pic and LCD running from 3.3V so connections are direct...
Pull ups on SDI, SDO and CLK lines... (no huggies)
For diagnostics i placed some LEDs inline with the pull up 1k resistors so i could see they flash. this includes the CS line...


On the LCD it said FSINIT ERROR then 2 6 0
so thats FAT_ERROR = 2, SDC_STATUS = 6 and SDC_RESPONSE = 0

In the SDFS file, SDC_STATUS 6 is labeled as initialisation error which isn't helpfull since it was doing the initialisation subroutine when it errored... SDC_RESPONSE i have no idea what this refers to, is it the status byte returned by the card?
If so, i swapped SDO and SDI around between straight and crossover just incase and same symptoms...

So, I'd appreciate any help as both cards do the same.

Thanks (bangs head on wall)
