-==== Bus Parrot Bus Pirate ==== 
-<wrap right> 
-{{:projects:busparrot.jpg?200}} 
-</wrap> 
  
-The Bus Parrot is a clone of the Bus Pirate general purpose I/O device for the RPi.  
- 
-In this instance communication is performed via the RPi built-in UART rather than using a USB bridge as in the original. 
- 
-=== Licence === 
- 
-Bus Parrot is derived from and uses the same licensing as the original Bus Pirate. 
-Visit this [[http://dangerousprototypes.com/docs/Bus_Pirate#License|page]] for Bus Pirate licensing information. 
- 
-=== Credits and Thanks === 
- 
-All the hard work was done by Dangerous Prototypes and it's really worth visiting their site for a proper overview of the Bus Pirate [[http://dangerousprototypes.com/docs/Bus_Pirate|here]] 
- 
-=== Build === 
- 
-This layout is a work-in-progress and is almost functionally the same 
-as the original the difference being the the power section. 
- 
-{{:projects:busparrot.png?200|SCHEMATIC}} 
- 
-All components should be available from CPC in the UK including the PICMicro.

-<CTRL>\ is the CONTROL key pressed and then backslash entered without releasing control. 
-Hold and release this and afterward enter upper case Q. This will quit kermit and return
