Digital Assistant, PDA) etc., preferably smart mobile phone etc..The smart machine possesses IR remote controller function, can
Launch telecontrol code.
As shown in figure 1, methods described includes：
In step S101, current telecontrol code to be launched and the corresponding carrier frequency of the telecontrol code are obtained
Rate.
In embodiments of the present invention, when needing transmitting telecontrol code, the telecontrol code is transferred to intelligence and set
Standby respective drive, current telecontrol code and the corresponding carrier frequency of the telecontrol code to be launched will be obtained by driving.
Exemplarily, by taking spi bus as an example, the output that spi bus launches telecontrol code for smart machine is pre-set
Port, then set up virtual SPI slave units driving, and generate application layer to driving interface.When needing transmitting telecontrol code,
The driving obtains current telecontrol code and the corresponding carrier frequency of the telecontrol code to be launched.
In step s 102, the clock frequency of default output bus is obtained.

In step S203, acquired bit is extended according to the conversion proportion, and according to acquired
Value on bit carries out assignment to the bit that extension is obtained.
For each bit, the bit is extended according to the conversion proportion, i.e., by each bit Bits Expanding
Into m, and it is the value on the bit to assign the value on each.
In step S204, the bit that the bit and its extension are obtained is stored according to big end pattern or little endian mode
Position.
Preferably, the bit that the embodiment of the present invention obtains the bit and its extension is according to big end pattern or small
End pattern storage is into default database.
In step S205, judge whether each bit of the telecontrol code to be launched has completed to change into.
In embodiments of the present invention, whenever completing after the conversion of a bit, the infrared remote control to be launched is judged
Whether each bit of code has completed to change into.If so, then performing step S206；Otherwise, return to step S202, is obtained infrared
Next bit of same byte or a bit of next byte in remote control mode, and the bit is turned
Change.
In step S206, the telecontrol code after conversion is launched according to the clock frequency.
By above-mentioned steps, compared using presetting the ratio between the clock frequency and carrier frequency of output bus as conversion
Example, conversion is extended according to the conversion proportion to each bit, and the telecontrol code after conversion passes through described default
The pulsewidth sequence that the clock frequency of output bus is launched is sent out with telecontrol code to be launched by corresponding carrier frequency
The pulsewidth sequence being shot out is identical, so that the IR remote controller of smart machine can be in fixed bus clock frequency
Launch the corresponding telecontrol code of a variety of different infrared protocols under rate, and ensure that the accuracy of telecontrol code.
