Analog input: C0-C15 16 channels Analog output: DIG. 16-channel analog signal switch CD74HC4067. Operating temperature range: -55☌ to 125☌. The card is also cut out of the "enable" pin - when the speed is high, it completely disconnects the common pin (all "off" switches. Internal switches are bidirectional, support voltages between ground and VCC, have low "on" resistance and low "off" leakage, and prevent cross stalk and switching. Using multiple panels, you can create similar arrangements for I2C, SPI, etc. If you want two-way communications, you can add a second board to route your TX microcontroller line to 16 RX devices. You can select one of the 16 devices to listen to music. For more example, you can use it to connect the TX pins of 16 devices to an RX pin on your microcontroller. What it allows you to do is use 4 digital pins, to control the flow of one pin to 16 others. It is available in a breadboard-ready DIP package, or, if you are as addicted to breakout boards as I am, SparkFun offers a breakout board SSOP version. If mux/demux also works with digital signals, you can use it to communicate TTL serial data from multiple devices. The CD74HC4067 is a 16-Channel Analog Multiplexer/Demultiplexer. This allows you to connect up to 16 sensors to your system using only 5 pins. To control it, connect 4 digital outputs to the address selection pins of the chip (S0-S3), and send the binary address of the channel you want (see data file for details). It works with both digital and analog signals (the voltage can not be higher than VCC), and the connection function in direction. This chip is like a rotary switch, it routes internally the common pin (COM in the diagram, GIS on the table) to one of the 16 channel pins (CHANxx). This is a branch board for the very portable 16-channel analog/digital multiplexer CD74HC4067.

A lightweight, low memory consuming CD74HC4067 Library for Arduino IDE based microcontrollers. I'm receiving the data in Pd as a group of 32 values, the two arrays I'm sending to Serial.write, but even though I do get the data, every time I start the Pd patch, the numbers go to a different place since the last time, randomly, which is not that good if you want to build a controller.We use cookies and similar tools that are necessary to enable you to make purchases, to enhance your shopping experiences and to provide our services, as detailed in our Cookie Notice. A Lightweight Library for CD74HC4067 - Arduino. Which works rather fine, with 16 potentiometers and 16 buttons. Anyone knows how to use this multiplexer with Pd? Btw, I know little about programming (at least with the arduino language).ītw, I ended up with this sketch #define CONTROL0 11 Trying the first code with 16 potentiometers attached to the circuit, today I was only getting jumping numbers. Trying to correct this I tryied this #define CONTROL0 11 I've checked the code in this web site but it wouldn't really do, so I searched a bit more and ended up with some code I partly wrote, partly copied myself, which is this #define CONTROL0 11Ĭhecking it yesterday with a couple of potentiometers (and the rest of the multiplexer inputs and arduino's inputs connected to ground), I was getting values from 0-255 over and over. Hi all, I've been trying to use the CD74HC4067 multiplexer with arduino to read 16 (at least) analog inputs in Pd (Pure Data).
