Now a two buss system the serial for inputs & outputs and I2C with RTC , 12bit 12port ADC , LM75 temperature sensors (to be added). You can check out "Working With MAX1238/9 12BIT 12 Channel I2C ADC" blog to see how I added the ADC. As soon as I get all the hardware tested and working I will make a circuit diagram and post it.
The code below has the 12bit ADC working.
