#171057 - You have more pins to mis-wire. Responding to: ???'s previous message |
I2C is incredibly simple to interface and use.
You have only two pins on the bus. But you must use proper external pull-up resistors. And of course connect the other 24C256 pins to 5V or GND as specified in the data sheet. Murray has supplied a bit-bang source code for you. Using a multi-pin ADC will require you to connect everything correctly. If you get your I2C working properly, a I2C variety of ADC is very simple to add to your project. David. |
