1. The problem statement, all variables and given/known data 1. SPI 2. i2c 3. RS232 4. RS485 Match The following interfaces to their category a. Asynchronous Serial, point-to-point b. Synchronous Serial with CS line c. Asynchronous data bus d. synchronous with address on the same line as data 2. Relevant equations 3. The attempt at a solution My guess so far would be 2-b, 1-c , 4-d, and 3- a... is this true?
