I'm not sure I know what you mean by SPI. Motorola has had something they call SPI since the '70's. If that's what you mean, there's nothing new about that. Are they all identical? Why would I want to use it? SPI stands for "Serial Peripheral Interface" Its an easy way to connect peripherals like serial ADC, DAC, display drivers, shift register as IO expansion, ethernet, CAN and so on and make the pcb many times easier as any parallel expansion bus. Most modern microcontrollers contain a SPI and the tendency goes to more powerful SPI, e.g. some ST ARM contain a SPI with 16 word FIFO. I like SPI too and use it very often, since it saves lot of time on making the pcb. I wonder why still no SPI-SRAM exist. Peter |
