Nusbio - UART Api

Overview

The Nusbio v1 USB device which offers

• 8 gpios with I2C and SPI support 
• for Windows programmable in any .NET language

is based in the FTDI chip FT232RL. Therefore it can also be used as a UART or serial communication.
This also known as an FTDI friend and can be used to upload code on an Arduino compatible that do not have a UART chip on board like the

• Diavolino from Evil Mad Scientist
• Trinket Pro from Adafruit
• Arduino Pro Mini

Extension

We used to sell the following extension which allows to connect some devices using the following UART pins: TX, RX, CTS,  RTS, VCC and GND.

 

In case you want to use the Nusbio's 8 GPIOs as USART communication here is the mapping.

• GPIO 0 - RI
• GPIO 1 - DSR
• GPIO 2 - DTR
• GPIO 3 - DCD
• GPIO 4 - CTS
• GPIO 5 - TX
• GPIO 6 - RX
• GPIO 7 - RTS

Remember that

• The pin 8 is VCC and pin 9 is GROUND. 
• Most Nusbio can be configured to be 5 volt or 3.3 volt

Activation

How do I use the Nusbio as a UART interface ?

Simply plug the device in the Windows machine and do not run any Nusbio code. Once plugged a COMX port should be available on the PC.
Use the general Serial Port class offered with your programming language
