have used high-end professional development system, will familiar with project concept. Essentially, this collection details data which managed program your behalf. AVR, have both Program Memory volatile Data Memory (EEPROM), with various security device options. project manager keeps this information together don't have remember reload various files every time programmer. project manager will allow store information like project name project identifier. also small notepad store comments about project. Before start programming session, must either open existing project start project. open project, create one, either going Project menu selecting "New" "Open", using "New Project" "Open Project" buttons toolbar. Once project open, load files that need program into device. Files loaded either using "Load" command File menu using "Open" icon toolbar. program will automatically decode your files whether they Intel format, Atmel Generic, Binary Motorola record. file choose will loaded into window, then displayed desktop. Therefore, have EEPROM Data Memory window top, will load data into that window.

Section Programming Using Board
Device Orientation
Before programming device using programming module, device adapter must inserted correctly into programming unit. adapter itself corner cut-off, which locates device matches marking main unit. This adapter should prefitted, replaced device programming life exceeded-refer your supplier obtain device adapter. orientation device vitally important. wrong then damage device. PLUG DEVICE ADAPTER WITH POWER SWITCHED damage Similarly, never remove device adapter with power Jumper used select either 3.3V programming. remove jumper jumper open 3.3V, insert jumper closed Jumper used Brown-Out detector voltage. Brown-Out 4.5V, insert jumper jumper closed Brown-Out 2.9V, remove jumper jumper open This should same voltage VCC. 3.3V Brown-Out 4.5V, then device will held reset will program.

Power Lead Connections
10-way programming lead inserted header-the key-way ensures correct orientation. computer connections shown "Connecting System" page 3-1. power supply 9-15V 7-12V plugged into power connector 5.5/2.1 Barrel. Power On/Off switch located next power connector. Insert device adapter before switching power power should light when power correctly applied. Your hardware ready programming. Refer "How Software" page details programming operations. programming indicates programming happening.

Section Brown-Out Detector
brown-out detector circuit used detect voltage drops. short glitch occurs power, this circuit ensures that processor resets properly rather than operating randomly. brown-out detector must same voltage circuit voltage, VCC- 3.3V 3.3V operation, jumper must removed (jumper open) operation must closed.

Using Switches LEDs
LEDs connected through resistor network Port switches connected Port switches LEDs disconnected, required. them, ensure that jumpers labeled "Port "Port closed. board also marked with port connection each switch LED. ports must correctly software input output. This accomplished setting direction control registers input output. Typical set-up code would r16,$ff ;move immediate into temporary store register DDRB,r16 ;set direction register ones output LEDs PORTB,r16 ;switch LEDs r16,$00 ;move immediate into temporary store register
DDRD,r16 ;set direction register zeros input Switches
Using External Connections
ports brought headers edge board. addition port pins, each header connection ground supply external circuits. Note this voltage, VCC, will either 3.3V depending setting jumper JP1, brown-out detector will operate. Note: your circuit draw significant current (>150 then heat sink will required on-board regulator-LM317. This device rated amps does need heat sink supply this current. your circuit will draw more than amp, need separate power supply. ports device connected headers marked Port Port Port Port Port Analog, Port layout headers same shown following diagram.
