Overview of Embedded Communication Protocols
Protocol Physical Lines Duplex Mode Sync/Async Topology Typical Application Scenarios Key Advantages 1-Wire 1 (DQ + GND) Half-Duplex Asynchronous One Master, Multiple Slaves Identity recognition, temperature sensors Minimal wiring, parasitic power supply IIC 2 (SDA, SCL) Half-Duplex Sync Multi-Master, Multi-Slave Onboard chip communication Hardware addressing, fewer pins SPI 3+n (SCK, MOSI, MISO, n*CS) Full-Duplex Sync … Read more
