Introduction

The uNiBoard version 1.1 is an ideal open source development platform f r Embedded and Real

Time Systems Programming. P wered by a RISC machine (ATMega128) that pr vides a thr ughput

f 16 MIPS and up t 128KB f internal st rage (flash), the b ard w uld be suitable f r any s rt f

embedded applicati n devel pment.

On-b ard peripherals like J ystick al ng with the c mmunicati n p rts (RS232) and the Gtkterm

driver (hyper-terminal f r Wind ws) make the b ard apt f r basic game devel pment in an

Embedded (n n-OS) as well as OS based envir nment. RT Kernels with small f tprint (uC/OS-II,

FreeRTOS, nut OS) can be p rted n the b ard t gain hands- n experience f Real time applicati n

design.

The b ard is p wered by the USB p rt. The b ard is als pr grammable thr ugh USB p rt thereby

making it c mplete stand-al ne lab equipment needing n thing apart fr m a basic PC/lapt p t get

started with the devel pment pr cess. The pen interface ( pen LED interface, pen p rts) extend

the platf rm’s r le f r pr t typing applicati ns like external device/sens r interfacing. The

c ntr ller by itself supp rts pr t c ls like SPI, I2C ( n-b ard I2C based RTC), UART (dual

pr grammable UART) which can be used f r multi-b ard c mmunicati n.

Additi nally, the b ard als features an n-b ard m t r driver which all ws t c ntr l up t tw

DC m t rs bidirecti nally. External supply, if required f r the m t rs can be pr vided with

appr priate hardware c nfigurati n settings.

The b ard al ng with its content-rich user manual is a perfect c mpani n t have f r

h bbyists/aspirants seeking a career in Embedded s ftware design, since it can acc mm date

preliminary applications like p rt c ntr l r sens r data pr cessing built on Embedded C t

complex real time applications built on RTOS like DAS (Data Acquisiti n Systems), embedded web-

server, FAT FS f r embedded systems and m re.

We plan t adhere t the Creative C mm ns license (Refer licensing terms), which has the

phil s phy f “Share, Remix, Reuse - Legally”. It means that any ne is all wed t pr duce c pies

f the b ard, t redesign it, r even t sell b ards that c py the design. Y u d n’t need t pay a

license fee t the Thin LABS team r even ask permissi n. H wever, if y u republish the reference

design, y u have t credit the riginal gr up. And if y u tweak r change the b ard, y ur new

design must use the same r a similar Creative C mm ns license t ensure that new versi ns f the

b ard will be equally free and pen.

Testing the Board

This secti n lists the pr cedure t test the b ard. T enable y u t quickly test the B ard, it c mes with a

test pr gram l aded. S , make sure y u first test the b ard bef re any pr gramming.

If y u have pr grammed the c ntr ller thereby erasing the test pr gram fr m the flash r in case y u find

that the sample pr gram has n t been l aded (which w uld be a rare case) then y u need t l ad the test

pr gram nt the b ard (refer t the secti n Pr gramming the B ard). The test pr gram is pr vided n CD

uNiB ard C ntents direct ry (inside sample c des). This c de tests the b ard’s peripherals (LCD, UART,

LED’s, Buzzer, and J ystick).

Testing the Board on Windows OS

F ll w the steps t c nfirm if the uNiB ard is OK.

STEP 1: C nnect the LCD n the B ard (refer t secti n Hardware c nnecti ns).

STEP 2: Use FRC cable t c nnect pen LED p rt and P rt C.

STEP 3: Using the serial cable c nnect uNiB ard t the PC.

STEP 4: If y u are using Wind ws OS then y u need install the USB drivers f r the uNiB ard nce (refer t

the secti n S ftware Installati n >> S ftware Installati n f r Wind ws OS >> Installing the USB drivers f r

uNiB ard).

STEP 5: Using the USB cable c nnect the uNiB ard t the PC.

STEP 6: Turn ON the B ard nce the drivers are installed c rrectly.

STEP 7: Open the Serial terminal and set the baud rate t 115200, parity t n ne, and st p bits t 1. S click

n Start >> pr grams >> Pr grams >> Access ries >> C mmunicati ns >> hyper terminal as sh wn bel w.

Thin LABS

STEP 8: Select File menu >> New C nnecti n then Enter Name f r c nnecti n and click OK.

STEP 9: Select the COM P rt where y u have c nnected the serial cable.

Thin LABS

STEP 10: Select the settings as given bel w f r this test pr gram.

STEP 11: Select Apply and then OK.

Thin LABS

STEP 12: Turn ON the B ard.

STEP 13: The test pr gram that we have l aded dem nstrates SNAKE game n any serial terminal which is

VT102 c mpatible. If everything is c rrectly installed y u sh uld be able t see a game f SNAKE (m dified)

as well as play using the J ystick.

While the pr gram is running y u will als be able t see the SCORE being displayed n the LCD al ng with

the versi n f the uNiB ard that y u are currently using. While the SNAKE eats up f d y u will be able t

hear the buzzer. Every time a new f d is generated y u will see the LEDs gl wing thereby utilizing all

uNiB ard peripherals.
