Tobi’s Corner

Inspired by http://tinkerlog.com/2009/04/05/driving-an-led-with-or-without-a-resistor/ I started to build a USB driven display. I ordered some big green 5×7 dotmatrix display from http://evilmadscience.com/ and had a look at v-usb.

What you get when combining those is a via USB controllable dotmatrix display. The PC related programming I did in Python using libusb and the python binding called pyusb. So the program should be cross platform compatible! Also python allows one to extend the functionality(e.g. checking for new mail, usb notifications of any type…) very easy.

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
