Arduino IDE setup
The MIAC board denion needs to be installed by
unzipping the contents of the “Arduino IDE MIAC
Hardware File” resource download into the
“hardware” directory of the Arduino IDE installaon.
For example:
“C:\Program Files (x86)\Arduino\hardware\matrix”
The MIAC will now be listed in the “Tools->Board”
menu.
The MIAC code library “MIAC Arduino IDE MIAC
Library and Examples” resource download is
installed by using the “Add ZIP Library” feature of the
IDE.
The AVR Arduino-Compable version of MIAC can be programmed from the Matrix TSL owchart
based IDE and simulaon applicaon Flowcode V7 or from the Arduino IDE for C++ development.
To prepare the Arduino IDE for use with MIAC, rst download the MIAC board denion les
“Arduino IDE MIAC Hardware File” and code library “MIAC Arduino IDE MIAC Library and Examples”
from the MIAC resources secon of the matrixTSL.com website.

Creating your project
First load the MIAC board denion by
selecng “Matrix MIAC Atmega” from the Tools
Board menu.
The “Matrix MIAC” library needs to be
included in your sketch via the Sketch
Include Library menu .

Example MIAC projects
Example MIAC sketches can be found in
the File Examples menu under “Matrix
MIAC”.
For example, the MIAC sketch
“MiacInputs” demonstrates basic cursor
posioning, text output to gLCD screen
together with examples of how to read
the keypad and the analogue inputs of
the MIAC.

The MIAC uses two UART peripherals to access and control the
RS232 and RS485 interfaces.
In addion, the oponal wireless modules can be accessed via
the UART channels. Note that the wireless modules are factory
set at 57600 baud and connected to UART 1. Please see the
MIAC Datasheet for details for changing the serial interface
conguraons.
The Bluetooth module can be used as a communicaon link by
simply connecng using the PIN code 1234.
The UART peripheral connecon informaon is detailed in the
table below.

Programming the MIAC
To deploy your project to the AVR (Arduino-
Compable) versions of MIAC, connect via a USB
cable and apply power the MIAC.
The USB communicaon port will be detected
and, if it is the rst me connected, Windows will
install the required FT230X drivers and serial
port. If it does not, please download and install
the FT230X VCP drivers from www.dichip.com
Select the COM port allocated by Windows for
the MIAC from the Tools Port menu.
Click the Upload icon to compile and send the
sketch to the USB connected MIAC.
Disconnect the USB cable, this is parcularly
important if the serial UART 0 is used in the
sketch. This is because UART 0 is disconnected
from the MIAC serial interface circuits when the
USB cable is connected.
