The course lesson will explains “How to work on Arduino” by using C Language. same I2C addresses devices are used; So we write the SoftwareI2C library to use digit port and analog port to enable multiple same I2C addresses devices work on Arduino. Also, be aware that there are some incorrect hookup diagrams on the internet for the Pro Mini. Using an I2C Scanner Sketch. Arduino Leonard uses D2/D3 for SDA and SCL or the separate pins to the left of D13. This library has many built-in functions that make programming the LCD quite easy. In the labview side I further filter the signals that come through the DAQ to remove noise and improve. But this is an advanced feature and I would advise just buying an I2C 16x2 LCD, they are … Talk about hitting two birds with one stone. We use a number so that it's not specific to the hardware. Aside from that, there are peripheral VIs to access your devices digital I/O, analog I/O, SPI, I2C, UART, PWM and more. We need to learn about the Wire library used in Arduino IDE.. Beagle LabVIEW Driver The Beagle LabVIEW Driver is a free and open-source. Remember to establish the map between Labview and Arduino, for example, you send character 'G' by Labview to Arudino, then Arudino reads this and run the corresponding codes.
