%P
%G
%C
I/O equal to a '10110011', where a '0' makes the bit an output, and a '1' makes it
an input (this is shown from B7:B0). In technical terms, this is setting the value for
TRISB
Puts a value to PortB. This will allow those pins that are set as output to be turned
on and off.
For example “%P12” would be interpreted as a binary string of 00010010 where if
a bit was previously set for an output, a value of 1 would place a logic high on
the terminal block and a 0 would place a logic low on the terminal block. If a
port bit was set for an input, this would not affect that signal.
Please note that the digital range is limited to the board voltage of reference
ground to 3.3VDC (typical) with a maximum current of 25mA per pin. It is typically
suggested that outputs are current sinking, rather than sourcing. Both reference
ground and power are available on the terminal blocks for user interfacing.
Get the input status for both port A and port B. This will read the A and B ports,
and return a string of values for each port on separate lines. For those locations
on port B that are outputs, a zero value will return. The format of the string is as
follows:
B=00[00000000]
If Port A is set for digital, the output would be formatted as
A=[00000]
If Port A is set for both digital and analog, the output would be formatted as
A=[00] 2:A9C0|1:6080|0:FFC0|
If Port A is set for all analog, the output would be formatted as
A=4:FF80|3:B000|2:5BC0|1:3740|0:FFC0|
Note that Port A analog values are always returned in a two bytes since the A/D
is 10 bits in value. The actual value is represented by [9/8/7/6/5/4/3/2] [1/0/-/-/-/-
/-/-]
XBee commands. This may be used to query the XBee module using the XBee AT
command set, or set a new value in the device. Setting a new value is always
followed by a write command to the module to store the new value in non-
volatile memory.
For example, sending a %CATID (return) would act as a query only, and return the
PAN ID value. However sending a %CATID5 (return) would set the PAN ID to a
value of 5 and store it to memory.
