As mentioned in the command descriptions, the CY545 can support a number of output devices,
selected by the Mode command. Two types of serial output are possible, and two types of
parallel output are possible.
The CY545 generates output from the string function, for user encoded messages, and from the
Query command, for current parameter values. The exact format of the output is determined by
the selected display and the ASCII or Binary command mode.
For standard serial output, the power-on default, the CY545 simply transmits each character of
a string or query on the serial output line, TxD. Every character between the quotes is sent for a
string, and the query parameter outputs are:
Where “X” is the parameter letter (N, P, R, etc.), and “vvvvv” is the five decimal digit or eight
decimal digit value of the parameter. The query output ends with a single carriage return
character.
When the CY325 based serial display is selected, the CY545 commands the CY325 to split the
display into two sections. The right hand section is used for string outputs, and no modifications
are made to the characters of a string. The left hand section of the display is used for the
parameter values, with each parameter assigned a different line on the display.
When a parameter query command is received, the output of the value involves moving the
display cursor to the proper display location, then printing the parameter value, and finally,
moving the cursor back to the standard display area.
The CY325 is a special display control chip available from Cybernetic Micro Systems.
