Word Formatted Data
There are three commands which may be accepted. All commands must end
in the special characters #$0D and #$0A which are CR (carriage return) and
LF (line feed). The accepted commands are:
nnnn,nnnn,nnnn,nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed on both the graph and bar graphs as follows: X/A, Y/B, Z/C, W/D.
nnnn:nnnn:nnnn:nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed the graphing component as follows: X, Y, Z, W.
nnnn=nnnn=nnnn=nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed on the bar graph component as follows: A, B, C, D.

DEMONSTRATION MICROCONTROLLER APPLICATIONS
The following microcontroller applications are designed to run on the JM
processors.
Logic Analyzer Application
The function of the Logic Analyzer Application is to play a different tone and
illuminate a different LED for each of the buttons pressed on the DEMOJM
board. The potentiometer controls the intensity of an LED on the DEMOJM
board, via a PWM signal.
Serial Accelerometer Application
This microcontroller application samples the state of the on-board three-axis
accelerometer using on-chip A/D converter channels. This data is converted
into ASCII characters and sent out using the serial pins of the JM processor.
These serial pins may be connected to P&E’s virtual serial port (which is part
of the Embedded Multilink design). Jumper J4 controls this connection.
P&E has two PC-based P&E Embedded Multilink Toolkit applications which
allow the serial port data generated by this application to be graphed. These
are documented in Section 6.4 - Accelerometer Demo Application and
