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:
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.
The nnnn values are 0000-FFFF and correspond in order to the data
displayed the graphing component as follows: X, Y, Z, W.
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.
The EM processor may obtain its power from the on-board regulator, USB
port, external battery, or through MCU_PORT J1. The on-board regulator
obtains its input from a 2.1mm barrel connector. The on-board regulator can
regulate the output to 3.3V. Power input is selected by using the J3, J4, and
J24 headers.
Select the USB port to supply microcontroller VDD. This is the default setting.
