Hi Everyone, I don't have any problem to configure the PIC to communicate with multiple SPI devices with separate SDI and SDO lines. Now, I come across a so-called "SPI compatible" device (TMP124) which has only ONE common SDI/SDO line. How do I interface the PIC to this one? Keep in mind that there are already some ICs on the SPI bus. Regards, Thomas __________________________________ Do you Yahoo!? Yahoo!
