THE PICKIT 2 UART TOOL WINDOW
The format of the serial signals on pins 4 and 5 is inverted such that a Start Bit = logic
low (V
no parity, with one stop bit.
The BUSY LED on the PICkit 2 unit acts as an activity light for the serial connection.
To open the PICkit 2 UART Tool window, select Tools>UART Tool… (Figure 7-2). The
PICkit 2 Programmer window will open and the PICkit 2 Programmer application win-
dow will close, as the programmer cannot be used while the UART Tool is active, and
vice versa.
FIGURE 7-2:
The UART Tool has two modes: ASCII and HEX. The current mode is selected and dis-
played by the buttons on the upper right hand of the display. The button corresponding
to the active mode will be displayed depressed. For example, in Figure 7-2 the ASCII
mode is active and so the ASCII button appears pressed.
The mode selection affects how serial data is displayed and entered in the window, and
the modes are explained in the next two sections.
The PICKIT 2 UART Tool is intended for use at logic level signals only. DO NOT connect
the PICkit 2 UART Tool to RS-232 +/- 12 Volt signals! Doing so may cause damage to the
PICkit 2 unit, your computer USB ports and the target serial port.
