06_software: 		y4项目中原接收板子
06_software_con：	y3 and y4项目中，接收发射的板子，用于验证接收发送同在一个板子的性能情况
			==> mcu:STM32F103C8T6

			==> 						MCU—IO		MUC-pin脚	备注
				1.WiSA发射模块配置		PB8=SCL		pin45		此配置需上电后延时约500ms操作
										PB9=SDA		pin46	
										PB5=BUSY	pin41
										
				2.接收端无线I2C控制		PB10=SCL	PIN21		"此I2C为单片机读WISA接收模块的相关信息
										PB11=SDA	PIN22		用于验证两个wisa的无线I2C"	

test_wisa_rx_tx:  这个代码是可以用接收TX端发给RX，RX再发给stm32f103c8t6的代码
