[dev65] Siemens TC65 Platform and SPI

[Marcin Mazurek]

Well, here is some code snippets which I use to communicate from TC65 to 
ATMega with SPI:

Open SPI channel:
AT^SSPI=1010,0000,0000,0000,0000

this is SPI channel in mode 0 on 250 kbps.

Now You have to open input and output stream:

            OutputStream atOs = atCmd.getDataOutputStream();
            InputStream atIs = atCmd.getDataInputStream();

After that, You have open SPI channel with streams to which You can 
write and read from.
That should be enaugh to communicate with any SPI device, but with SD 
card is one problem.
When you want to initialize SD card, you have to change the state of CS 
line, and when You open SPI channel, You cannot controll CS line.
Thats what I know. I hope this will help You.
And I hope You'll chare your experience with TC65 and SD card. Let me 
know, if You'll have any problem.

Best regards
Marcin Mazurek
