  • Page 7: Connect To Mcu

    Description（STM8L MCU） The UART module is TTL level. For some M CU works at 5VDC, it may need to add 4-10K pull-up resistor for the TXD & AUX pin. 5 Function description 5.1 Fixed transmission Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co.,Ltd.

  • Page 8: Broadcasting Transmission

    For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04;  When module A is the receiver, it can receive the data sent from all modules under channel 0x04, the purpose of Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co.,Ltd.

     When AUX = 1, it does not mean that all the UART data of the module have been tra nsmitted already, perhaps the last packet of data is still in transmission. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co.,Ltd.

  • Page 10: Configuration Procedure Of Module

    AUX stays on the high level, the operating mode switch can be affected immediately. When the user switches to other operating modes from mode 3 (sleep mode) or it ’s still in reset process, the module will reset user parameters, during which AUX outputs low level.

  • Page 11: Operating Mode

    This operation is very flexib le and efficient. It is totally designed on the basis of the user MCU ’s convenience, at the same time the work load and power consumption of the whole system have been reduced and the efficiency of whole system is largely improved.
