Start your routine in C/C++ including the following libraries: #include It should be something like this: tty.usbserial-0000103D This hardware allows the Atmega chip to receive serial communication even while. The native serial support happens via a piece of hardware (built into the chip) called a UART. It is possible just checking the Tools / Serial Port menu before and after plugging the board to see identify the corresponding port, select the appropriate one from the list. The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). Identify in your computer the Serial port created when the Wiring i/o board is plugged. You can easily communicate with other devices via RS-232 protocol (for example with PC, see the figure at the end of the topic RS-232 HW connection). The mikroC PRO for PIC UART Library provides comfortable work with the Asynchronous (full duplex) mode.

Step one: Program the Wiring I/O board with the Wiring language, the easiest way is to use the examples that are already published in the Learning section to read the data from the ping or the potentiometer (there are different).Ĭode for the Ultrasonic Ping Sensor / Parallax PING Sensor The UART hardware module is available with a number of PIC compliant MCUs. The Ultrasonic ping goes to the digital pin one, and the potentiometer goes to the analog pin one. Plug the Wiring I/O board using a USB cable to your computer, connect the ultrasonic ping sensor and/or the variable resistor to the Wiring I/O board. You will need the parallax ultrasonic ping (digital) or the potentiometer (analog).

This tutorial shows how to read serial data from the Wiring hardware coding in C/C++ in UNIX based machines (OSX and Linux), the examples read data from a Wiring board where an ultrasonic ping sensor or a potentiometer is connected.
