Chapter F – Mux / demux
M74HC4052 Description:
How can we use it?Use A and B to connect X-com and Y-com to one of four pairs of pins E.g. if A=0=B, then X-com is connected to 0x and Y-com is connected to 0YE.g. if A=1=B, then X-com is connected to 3x and Y-com is connected to 3YSignals can travel in either direction
How can we use it?Connect V EE to ground and VCC to 3.3V to operate in digital mode with RPi.Connect the Rx and Tx lines of one HMC5883L to 0X and 0YConnect the Rx and Tx lines of the other HMC5883L to 1X and 1YConnect B to groundConnect A to an output GPIO pin.Set A low to access the first sensorSet A high to access the second sensorSet INH to ground
