KIT Shield Arduino I2C bus expansion with IO 8 IN + 8 OUT Relay MANUFACTURER: F.Elettronica REFERENCE: FT1079K EAN CODE: I/O expansion shield for Arduino based on the MCP23017 chip produced by Microchip.Attention, the product is a KIT and therefore you will be given the components to be soldered with an electronics soldering iron and everything needed to recreate the device as shown in the image. The KIT includes easy-to-understand illustrated instructions in English. Level of experience required for assembly: MEDIUM Also available in KIT version or assembled version on EBAY | MECTRONICA STORE MANUAL I/O expansion shield for Arduino based on the MCP23017 chip produced by Microchip. It has 8 digital inputs, each of which has a protection diode, a pull-up resistor and an LED; 8 relay outputs with relative status LED. Communication with the MCP23017 is based on the I²C-Bus, therefore the library uses Arduino's “Wire.h”. The I²C bus is made up of 2 pins (SDA, i.e. data, and SCL, i.e. clock); on the integrated circuit they are available on pins 13 and 12, brought to the corresponding pins of the Arduino board. The shield provides the possibility of bringing (via a jumper) the interrupt pin of the MCP23017 (INTB, pin 19) to the input on two different Arduino pins (D2 or D4) in order to adapt it as much as possible to actual use. The I²C-Bus address of the MCP23017 is selected via dip switch which allows you to connect up to 8 different shields without them interfering with each other. The kit includes all the components, the drilled and silk-screened base and all the small parts. Expansion shields are available to expand the communication and processing capabilities of the Arduino board. You can buy them here: EBAY | MECTRONICA STORE Arduino I²C I/O Expander Shield Library We have developed an Arduino software library that provides all the routines necessary for the detection of connected shields and the related I/O management (you can download this library from this page). Communication with the MCP23017 is based on the I²C-Bus, therefore the library uses Arduino's “Wire.h”; there is a "begin(int i2cAddress)" function to initialize the single shield identified by I²C address, and also an "init()" to correctly program the internal registers of the chip according to our needs, and finally a "pinMode(int pin , int mode)” to indicate whether individual I/O pins are input or output. In addition to the initialization functions, the instructions that particularly interest us are the “digitalRead(int pin)”, “digitalWrite(int pin, int val)”, “digitalWordRead()” and “digitalWordWrite(word w)” which, respectively, they allow you to read the state of a single input pin, write a single output pin, read the state of all the input pins (8 in our case) and finally write the state of all the output pins (always 8 ). Input management can be done via interrupt; there is therefore a specific "pinDisableINT(int pin)" function which allows you to configure the single pin as an interrupt generator or not (in particular applications it could be useful to have the possibility of not setting all the input pins as interrupt generators, but do it selectively).
