Iv got a project that requires me to read the SPI data that an older motorola 68HC11 microcontroller sends to a shift register. I want to use a mega328p to read this data. Im not sure how to go about this. the 68HC11 gives me the MOSI, and clock lines that go to the shift register. can i tap off those lines and connect them to the miso and clock of my mega328p? I would like to get rid if the sift register all together as it is not needed if i can get the 68HC11 to talk to the mega328p. I dont need the 328p to talk back to the 68hc11, and there is no way to talk back to the 68HC11 anyway. The shift register is an older motorola with an internal moto part number, 22 pin, i cant find any info on that IC. all i need to do is read the data the moto micro is spitting out. Is this possible?
