The LED moving font is built up of separate modules consisting of 64 LEDs each (8×8 matrix). The modules can be cascaced according to the desired size of the font. Each module is controlled by the LED display driver MAX7219 (or MAX7221) which can drive 64 LEDs.
“Using this programmer you can program the internal flash of the microcontroller AT89C2051 from Atmel. The AT89C2051 programmer is connected via the serial RS232 interface to a PC. In comparison with other programmers, you do not need a special software, a terminal program is sufficient.”
Other Projects here are LED moving font, TV tuner, LED clock, Serial-I²C-Converter, AT89C2051/ATtiny2313 evaluation board, AT89C2051 programmer, I²C-I/O-Expander, AVR JTAG Emu, Displays.
