AVRTer is not only a Terminal Emulation for AVR, it’s a Terminal build with an AVR.

The Terminal is build with an ATMega8 and a 640×240px GLCD. The Terminal can be used as a RS232 debugger.The Display Routines are from Holger Klabunde. Have a look at his Webpage: http://www.holger-klabunde.de/

The Keyboard routines are based on the ATMEL Application Note AVR313 and written by V. Brajer.

avrDotmatrix uses a 5×7 dotmatrix display and an ATMega8 to create a nice display with scrolling!

avrDotmatrix - Is a 5×7 LED Matrix Display controlled by a ATMega8 to display scrolling text, time or temperatures. The pattern is generated with multiplexing the 5 matrix columns and setting the correct row bits.

This projects is still in development and i’m gonna add a temperature sensor (LM75), a I2C EEProm and maybe a IR receiver for transmitting texts to the display wireless.

avrCCD is an Interface to TSL1401 128×1 Linear Sensor Array with Hold.

The TSL 1401 linear sensor array consists of a 128×1 array of photodiodes. The pixel measures 63.5um (H) by 55.5 um (W) with 63.5 um center to center spacing.

About IgorPlug:

I’ve tried the IgorPlug USB-RS232 Converter on an ATMega8 running with 12MHz for better USB Timing. As reference I used the information on Igor’s Homepage and the Application Note from ATMEL.

Features:

• 800 Byte FIFO Buffer
• Baudrates from 300 to 115200
• Databits: 5,6,7,8; Stopbits: 1,2; Parity: none, even, odd, mark, space
• Three 8-bit I/O Ports
• Direct Interface to internal EEProm
• eventually possibility to use ATmega8 peripherals (not yet implemented)
• Possibility to add own function

This project describes howto create a waveform generator with an AVR Microcontroller and an Analog Devices DDS circuit.

The AD9833 is a programmable waveform generator capable of producing sine, triangular and square wave output signals up to 12.5 MHz (clocked with 25MHz).

The Interface Boards contains all basic components the DDS Chips needs to run. If you compare the component count with that of a MAX038 circuit you will see, that there are less here.
