How to use the CAN ?
I would like to receive a voltage from 0 to 5V and then display it on the LCD screen. I can not use Analogin because they are used by the lcd screen. So I would use pine 27, 28, 29, 30 of mbed NXP LPC1768. How?
Thank you

CAN is a digital serial bus used on cars, it can't be used as an analog input.
Why is the LCD using the analog in pins? Driving an LCD shouldn't need that ability. If it's just that those pins are used then can you move the LCD to other pins and then use the analog inputs for analog input?
Also the analog inputs are only 3.3V maximum. If you have a 5V signal you'll need to use some resistors to reduce the voltage.
