2 • WINAVR - WINAVR is a C Compiler for AVR microcontrollers. Run the installer if you want to use C language for your AVR development. Documentation is included. WinAVR will be automatically linked to AVR Studio. Summary The only software you need to install to start with are AVRStudio for code development, WinAVR if you want to w ...

3 Make sure you use the correct header on the STK300 board – it is the box header next to the 9-way D-Type connector and power input. Power Supply 4) Connect a power supply to the board. The connector type required is 2.1mm barrel, centre negative or centre positive. It can be 7-12VAC or 9-15VDC, with a current capacity greater than ...

4 Load File Once the board is connected properly, the next step is to load a file into the buffer. All operations are carried out on the data in the buffers. There are two buffers, one for code – Flash and one for data – EEPROM Go to File Menu and choose Load > Flash, and select a file such as Samples > STK300 > LED Flash > LEDfla ...

5 AVR microcontroller default fuses New AVR devices come with the Clock Source set to RC Internal Oscillator by default. The actual speed of the oscillator varies from 0.5MHz to 4MHz depending on the device. This means that programs will run slower than expected, because the AVR is NOT running from the 8MHz clock on the STK200 board. ...

6 Pop-up Warnings This displays a message box if there is a verify error. Useful if repeated Auto Program operations are carried out, when it can be easy to ignore errors. Setup This can also be selected by clicking the Setup Button. It covers a variety of settings, which are not needed on STK300 board, except Communications Device. T ...

7 Expansion Headers All the device port pins are brought-out to pin headers on the edge of the board. The layout of these connectors is shown below. All the ports are available - Port A to Port G – and all have the same layout except Port G. Port G is a smaller port and not all pins are brought-out because they are used by RTC circ ...

8 Real Time Clock A 32768 Hz crystal is connected to TOSC1 and TOSC2 pins - Pin 19 and Pin 18. These pins are also Port pins PG3 and PG4, but are not connected to the expansion headers. This crystal can be used to generate a 1 second pulse by setting Timer 0 to Asynchronous Operation - see Atmega128 data sheet for details JTAG Header ...

10 29C256 Pin-outs 24C EEPROM Socket The board is fitted with a socket for 24C EEPROM Chip. This is an I2C device, or in Atmel speak, a Two Wire Serial Interface (TWI). The socket is connected to Pin 25 and Pin 26 of the Atmega128. These are SCL and SDA pins or PD0 and PD1. The socket layout is shown below. A full description of the ...
