Spi without cs
WebAdvantages of SPI 1. Full duplex communication 2. Higher throughput than I²C protocol 3. Not limited to 8-bit words in the case of bit-transferring 4. Arbitrary choice of message size, contents, and purpose 5. Simple hardware interfacing 6. Typically lower power requirements than I²C due to less circuitry. 7. WebApr 11, 2024 · Since it is a write only device, it does not need the SPI MISO line hooked up. The module also does not bring the CS pin out to the interface which helps to lower the pin count. The downside is that it cannot be used with other SPI devices on the same bus at the same time. Module Connections Connection to the display is via a 7-pin header.
