Function
1. Simple Transmitter ASK or OOK.
2. SCK PIN=high, TH01 will auto transmit data by 60 seconds period.
3. Each RF time it will transmit five bytes preamble code followed by five same frames data. Each
frame data format is "SYN + A mode data format”. So each RF time is 168ms~403ms.
4. Any time SCK PIN=high will repeat step2.
