I see in the hardware topic about the digital and analog input and output lines but didn't see anything about the UART lines.
I want to connect a Maxium DS18B20 to the UART and found some code to try and use. I don't want to burn anything out so how do I safely attach this to the UART? As I understand since it is a one wire the TX and RX need to be connected to the DQ line on the DS18B20. Do I just connect them both together?
One schematic for a different board using the UART for this used a Schottky Diode between the two with the RX connected directly to the UART pin and the TX goes through the Schottky. They have a pull up resister from +3.3v to the DQ line too.
I hope that made since. I'll have to use the UART's in the back connector as I'm using the UART 0 for LCD Display.
Thanks for all your help,
