#101178 - Is HW I2C easier? Responding to: ???'s previous message |

use a processor that has HW IIC and put the Aspirin bottle away. Michael Karas said:
I have used the on-board I2C interfaces in both the SiLabs C8051F12x series and the 'F020 parts. It is my honest opnion that the use of the I2C engine is not the easiest thing in the world to implement....especially if you try to use it in the interrupt driven manner and you are new to coding with state machines. Since there is a plethora of on-line examples of software bit-bang I2C code around it may just possibly be easier for lesser experienced programmers to get their arms a software bit bang implementation.
