| IIC to GPIO Shield V2.0 SKU DFR0013 Contents • 1 Introduction • 2 Specification • 3 Board Overview • 4 Tutorial Requirements Connection Diagram Sample Code • 5 Library Explanation Library Functions Pin map • 6 FAQ Introduction Having troubles with inadequate digital I/O when using Arduino with robots or interactive media? This IIC to GPIO shield helps you solve the problem, Arduino has only two data lines SCL-Analog PIN5, SDA-Analog PIN4 and IIC can transfer I / O module communication, to convert the 16 digital IO ports, read-write. 8 simultaneous parallel modules, each module can be set to address. Specification • Module power supply +5 V • 16 Digital I/O port comes with internal pull-up • Can be set to eight addresses address range of 0x20 ~ 0x27 • 8 modules simultaneously in parallel IIC bus need to pull together • Module Size 56x53mm 2.21x2.08 in Board Overview Plug = 0 Unplug = 1 A2 A1 A0 IIC Address 0x20 Default 0x21 0x22 0x23 0x24 0x25 0x26 0x27 Tutorial Requirements • Hardware DFRduino UNO x1 IIC to GPIO Shield V2.0 x1 Button module LED module • Software Arduino IDE V1.6.5 Click to Download Arduino IDE from Connection Diagram Sample Code In this section, we will use an Arduino library written by nicoverduin Github Library. About Library installation. 1 #if defined ARDUINO && ARDUINO >= 100 2 #include "Arduino.h" 3 #else 4 4 #include "WProgram.h" 5 #endif 7 #include "clsPCA9555.h" 8 #include "Wire.h" 11 PCA9555 ioport 0x20 ; 13 void setup 15 ioport.pinMode 7, OUTPUT //Set GPIOs pinMode LED 16 ioport.pinMode 8, INPUT //Button 19 void loop 21 if ioport.digitalRead ED8 == LOW ioport.digitalWrite 7, LOW ; //Turn off Led 25 if ioport.digitalRead ED8 == HIGH ioport.digitalWrite 7, HIGH ; //Turn on Led Library Explanation Library Functions • pinMode same as standard Arduino • digitalRead same as Arduino • digitalWrite same as Arduino Pin map P0.0~P0.7 map to GPIO 0 ~ 7 or ED0 - ED7 P1.0~P1.7 map to GPIO 8 ~ 15 or ED8 - ED15 |
