Relevant key device information applied in this article: SM5262 CS901, as shown in the figure, is an eight-way remote control transmitter composed of CS901 module and digital encoder SM5262 (same as PT2262). The buttons SA1~SA8 and diodes VD1~VD13 form an eight-way matrix input. The circuit is used as the eight code input circuits of the remote control transmitter. Since pins 7 to 13 of SM5262 are address/data common terminals, if they are used as data input terminals, the circuit has a total of six data input terminals. When all of them are used as data input terminals, a total of 26=64 can be formed, that is 64-channel remote control transmitter. Only four input terminals D1 ~ D4 are used in this circuit. It can form a 24=16-channel remote control transmitter. In fact, this circuit only uses half of it, that is, eight channels, to form an eight-channel remote control. launcher. The digital input codes of this eight-channel transmitter are: SA1-0001, SA2-0010, SA3-0011, SA4-0100, SA5-0101, SA6-0110, SA7-0111. SA8-1000, the remaining codes 1001-1111 are not used.
