The 8-line remote control emitter(CS901) circuit

In the figure is the 8-line remote control emitter which is composed of the CS901 module and the digital encoder SM5262 (the same with PT2262), the keys SA1～SA8 and diodes VD1～VD13 compose the 8-line matrix input circuit as the encoding input circuit of the emitter. As the 7~13 pins of SM5262 are the address/data sharing terminals, if they are regarded as the data input terminal, the circuit will have 6 data input terminals in total, when all their functions are taken as the data input, they can compose the 26=64, i.e the 64-way, remote control emitter. In the circuit, only 4 terminals of D1～D4 are put in use.
