%V (Board Voltage)

This command applies to the XTC RF Module.

Reads the supply voltage to the module's VCC (pin 2).

The conversion of the hex value returned by %V to Volts is VAL/65536 = Volts.

Example:

2.8 VDC = 2.8 * 65536 = 0x2CCCD

3.3 VDC = 3.3 * 65536 = 0x34CCD

Sample output

3.27 V (when CF = 0)

345E3 (when CF = 1) 1 When CF = 1 (default), the firmware shows a hex integer that is equal to (voltage * 65536d).

3.27 (when CF = 2)

Binary command
