Abstract

A radio control transmitter, and more particularly, a digital radio control transmitter uses analog digital conversion within the transmitter and provides improved display characteristics of the trim settings involved with respect to the various control sticks for providing radio remote control of the movement of model objects such as model airplanes, model helicopters, model cars or the like. An improved display shows the various trim characteristics and actual settings of the various control sticks during the operation.

Claims

1. A radio control transmitter comprising:

a data conversion section for generating digital output signals responsive to the operation of control sticks;

a setting section for setting a trimming operation of said control sticks for adjusting said output from said control sticks and for generating output signals;

an operation section for processing the output signals of said data conversion section and setting section to generate output signals;

a high-frequency section for modulating the output signal of said operation section into a high-frequency signal in the form of a predetermined shape and generating said signal; and

a graphic display section of displaying control characteristics of said control sticks with respect to a controlled object responsive to the output signal of said operation section.

2. A radio control transmitter as defined in claim 1, wherein said display section displays the number of pulses supplied to a servo motor of said controlled object in the form of a bar graph responsive to the operation of said control sticks.

3. A radio control transmitter as defined in claim 1, wherein said display section displays movement of a controlled site of said controlled object responsive to the operation of said control sticks.

4. A radio control transmitter as defined in claim 1, wherein the mechanical versus electrical characteristics of said control sticks are displayed.

5. A radio control transmitter as defined in any one of claims 1 to 4, wherein said setting section includes a storage section for storing control characteristics of said control sticks with respect to a plurality of controlled objects.

6. A radio control transmitter as defined in claim 5, wherein said setting section permits said control characteristics with respect to a plurality of said controlled objects to be writable and readable with respect to said storage section.
