Simulate two sensor and send information back over the iBUS to the receiver (and back to transmitter
as telemetry).
- serial - monitor output (debug output to PC, this is through the build-in USB)
- serial1 - connected RX of the serial port to the ibus receiver pin
Connect the (TX) pin also to the RX/ibus connection using an 1.2k Ohm reistor or 1N4148 diode
(cathode=white ring of the diode at the side of TX2)
sensor types defined in IBusBM.h:
#define IBUSS_INTV 0 // Internal voltage (in 0.01)
#define IBUSS_TEMP 1 // Temperature (in 0.1 degrees, where 0=-40'C)
#define IBUSS_RPM 2 // RPM
#define IBUSS_EXTV 3 // External voltage (in 0.1V)
