The MCP23008 I/O port expander circuit we will build with an Arduino microcontroller to read inputs from pushbuttons is shown below. This circuit will have 3 pushbuttons on pins 10, 11, and 12. Now, will explain the circuit hardware connections. To the first 3 I/O pins, pins 10, 11, and 12, we connect pull-down resistors.

How to use mcp23017

MCP23017 uses just two pins to communicate with a central controller providing you 16 digital I/O pins in exchange. These digital I/O pins can be configured as either inputs or outputs and operate similarly to the built-in digital I/O ports on the Raspberry Pi hardware.

How to use mcp23017

To power the MCP23017, connect the VDD pin to +5V voltage rail, and the VSS pin to the ground rail. Connect the SCL and SDA pins on the MCP23017 to the I2C pins on the Raspberry Pi hardware. Set the I2C device address of the MCP23017 to '0x20' by grounding the A0, A1, A2 pins. Connect the RESET pin to the +5V voltage rail.

Re: Running a MCP23017 on 5V. Postby username » Mon Feb 17, 2020 3:31 am. That AC diagram your referring to is to show what the pin with those loads will meet for the timing specifications. Yes, you can power the MCP23017 from 5V. The only thing you need to do is run your 2 pullup resistors to +3.3v and not +5v. Top.

    The MCP23017 may be used for both input our output operations. The functions shown below are intended for relay control, but are equally as effective for GPIO Port Output operations. To control relays (or set the state of GPIO outputs), data must be stored in the correct register.The following netlist and diagram show you how connecting the MCP23017 to the Arduino is very simple.

    Adafruit Industries, Unique & fun DIY electronics and kits MCP23008 - i2c 8 input/output port expander : ID 593 - Add another 8 pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two i2c pins (these can be shared with other i2c devices), and in exchange gives you 8 general purpose pins. You can set each of 8 pins to be input, output, or input with aThe MCP23017 can be powered with +5V. Therefore, we can connect V DD to the 5V terminal of the arduino. We connect V SS to ground. This completes the powering that's necessary for the MCP23017. The GPB0-GPB7 and the GPA0-GPA7 are the 16 I/O ports. NC is Not Connected so we leave that unconnected (or floating). SCL is the serial clock line.

I wouldn't recommend the MCP23016 because it's more complex to use and doesn't offer any benefits. The MCP23018, on the other hand, is not so widely used and that's why I introduce the MCP23017 in this post.

    This is done by using the MCP23S17 chip instead of the MCP23017. The wiring is virtually identical, except that two more wires need to be run to the Arduino (SS and MISO), and two other wires are run to different pins (CLK and MOSI).3 pins are used to address different ICs, I believe it is 15,16, and 17 on the MCP23017. Using a combo of sending each pin either a high signal or low (5v or 0v), we can set an address. Do the math and you basically can think of it as a digit combo lock.
