#105871 - Inappropriate Design Choice? Responding to: ???'s previous message |

In order to reduce the hardware, I decided to use I2C bus which is available on all micros now instead of RS485 for example . Please note that I2C is not designed for this sort of thing: http://www.8052.com/forum/read.phtml?id=105293 Interface like RS232, RS485 are specifically designed for external connections - part of the reason they appear more expensive is because of the protection they provide against the abuse which is to be expected in external interfaces! This doesn't necessarily mean that I2C is wrong in your particular application - but it's something you need to think about... |
