Hello,
Adopt international standard SIF communication protocol, and the interface is universal and convenient.
The master-slave mode adopts single line one-way transmission, that is, only one transmission line is required.





i need to transmit above given example data using single-wire communication.
if you known any one guide me.

Hi,

no problem for a PLD, but should be no problem for a PWM hardware inside the STM, too.
Basically I see just 3 patterns
* 1 bit time 100% HIGH = START
* 33% LOW, 67% HIGH = 1
* 66% LOW, 33% HIGH = 0

I guess the STM even can handle this "waveform generation" via DMA.

The protocol is so slow that it can be handled by almost any uC without particular hardware acceleration.

Hello Sir,
Please Explain about "SIF Communication Protocol"
what is and how it's work?

The question should be answered by the original poster. I'm not aware of a commonly known "SIF" serial protocol. There are several industry standard bidirectional single wire protocols like Dallas one-wire or SIM card SWP.
