To
implement the “G” command (“Go” command, refer to
LEVEL 1
COMMANDS
table) to have the following serial output columns
reported from the monitor: Time Stamp, Overall Hydrogen Reading,
the Peak Hydrogen Reading, Calculation Errors, and the Heater
state.
From the
FORMAT <fmt>
table above, you identify your desired
columns with its corresponding bit value:
<fmt> Descriptions
<fmt> Bit Value
Time Stamp
1000 0000
Overall Hydrogen Reading
0000 0010
PCB Temperature
0010 0000
Sensor Temperature
0001 0000
<fmt> 4 Bit Value Combination:
1011 0011
Now use the
4 BIT-TO-HEXADECIMAL
table above to convert this 4 bit value combination into a
two place hexadecimal value:
<fmt> Two Place Hexadecimal Value

Again, use the
4 BIT-TO-HEXADECIMAL
table to convert this 4 bit value combination into a two
place hexadecimal value:
<opt> Two Place Hexadecimal Value

To have the Time Stamp, Overall Hydrogen Reading, the Peak Hydrogen Reading, Calculations
Errors and Heater State columns continuously reported, you will implement the “G” serial command
as follows at the
