#125255 - implementing I2C in software Responding to: ???'s previous message |
Do you mean using 2 data ports to simulate SDA and SCL? In that case I guess a simple AT89C2051 would do? Are there any speed limitations in implementing it this way, i.e. getting the data ports to switch fast enough for standard 100KHz I2C? Are there any resources I can refer to? |
