Abstract
A programmable electronic circuit is disclosed. The circuit includes a CPU, signal-generating circuitry, and RC circuitry having at least two capacitors, such that when both of the capacitors are switched into the RC circuitry by the CPU, a signal is produced from an output of the signal-generating circuitry that is longer in duration than when one of the capacitors is switched into the RC circuitry.
Claims20
An electronic device comprising:
- a CPU;
- and
- a signal-generating circuit, wherein the signal-generating circuitry comprises RC circuitry having a first capacitor and a second capacitor, such that when the first capacitor is switched into the signal-generating circuitry by the CPU and the second capacitor is switched into the signal-generating circuitry by the CPU, an output signal is produced from the signal-generating circuitry that is greater in duration than when the first capacitor is switched into the signal-generating circuit and the second capacitor is not switched into the signal-generating circuitry.
A method for programming an electronic device, comprising:
- generating a voltage square wave at a node of signal-generating circuitry;
- generating a charge voltage signal from the charging of at least two capacitors, which are switched into the signal-generating circuitry, that is greater in length than when one of the two capacitors is switched into the signal-generating circuitry;
- inputting the charge voltage signal to an input of the adder circuit;
- outputting to the node the charge voltage signal during the time when a voltage of the voltage square wave is lower than the charge voltage;
- and
- outputting the voltage of the voltage square wave when the voltage of the voltage square wave is greater than the charge voltage.
