i2c 24c256 ex_extee.c setup_spi(FALSE)

[javabear]

Hi,

[frank@picard frank]$ ccsc +v
PCM compiler version 3.168 (linux, RH9)

I was running some test code from PCM programmer 24lc256.c
on a pic16f876 and 24c256 eeprom via i2c.

All is well, thanks for the example code.

Now the strange part (or maybe I am tired).

if i run ex_extee.c, reads and writes do not work
reads return 0xff and writes hang.

however if I add 1 extra line after init_ext_eeprom

init_ext_eeprom(); <-- existing line, no change

setup_spi(FALSE); // added by me - program now works ... aaarrgh !!!!!!

then it all works.

I have read some discussions about using setup_spi(FALSE); so
now I am confused.

Has anyone else seen this ??

Thanks
