I'd be very thankful if you can send me the subroutines, perhaps I can
find them useful!
I'm sending you my e-mail address, thanks again!

Hi Giulio,

I tried SPI Peripheral of TMS320lf2407 to communicate with SPI RTC
about 3 month ago and It didn't response me.
At last I create a manual SPI subroutines that works. I think they an
help you. Tell me If you want them.

Good Luck!

I'm trying to implement a 4-pin SPI interface between an EEPROM and a
TMS320DM648 DSP (in Code Composer Studio), but I'm getting no results:
when I try to read EEPROM status register, I always 0xFF in the read
buffer (that is a senseless value), as if the lines were in high
impedance state.
Does anybody have a working example? I think I'm not driving Chip
Select correctly, but I can't find out the problem.

Thanks in advance
Giulio
