avrCCD

Saturday, November 11th, 2006

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

 

CCD

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

AD9833 / AD5932 Interface

Saturday, November 11th, 2006

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).

AD9833 Board

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.
