View source for Bus Pirate: UART

== Summary == 

This documentation describes the basic steps to connect to an UART-capable device using Bus Pirate v3.6

== Requirements ==

* Serial connection to the Bus Pirate (e.g. using Putty)
* UART-capable device to connect to

If the currently installed Firmware doesn't support UART mode, check [[Bus Pirate: First steps]] to install a different firmware.

== UART Connection ==

=== Step 1 ===

Connect the Pins of the Bus Pirate to the UART-device:

|- style="font-weight:bold;"
! Bus Pirate
! UART-device
|-
| MOSI (TX)
| RX
|-
| MISO (RX)
| TX
|-
| GND
| GND
|}

=== Step 2 ===

Connect to the Bus Pirate using serial connection (e.g. using Putty) with baud rate 115200.

Type <code>m</code> to start the mode selection.

Select the UART and enter the settings (baud rate, etc.) according to the specifications of the UART-device.

After setting the correct values, type <code>W</code> to enable the power supplies. Now it is possible to read values using <code>r</code>, send values like ASCII text using <code>"text"</code> and more.
