#93881 - HW solution Responding to: ???'s previous message |
Although this was made with a simple PIC processor, it is the same with any other, which NEED NOT have SPI interface.
74HC164 is an 8 bit shift register. MOSI is the output from Master, and SCKM is SPI clock. SPI clock pulses are counted by the internal counter, so the reload register should be set to - 8, and then, in the interrupt routine, only reading of the shift register is made. So it is all very fast and simple.
