LED Matrix Fairplay hack
Details from LED Matrix Fairplay hack
Using an old Fairplay Scoreboard LED matrix to display scrolling messages (one of which was also for the kiddos birthday, scrolling "HAPPY BIRTHDAY")A PIC 16F870 was used for the controller. The factory controller was ditched as I was unsure how...

Custom parallel processors in Verilog/FPGA
Details from Custom parallel processors in Verilog/FPGA
Nakano, K., et.al.(refs below) describe two versions of a small stack machine suitable for implementation on an FPGA and they give the Verilog source code on their web site. The design was ported to the DE2 board and extended to have a richer set of...

Chemical Reaction Solver in Verilog -- NO ODEs!
Details from Chemical Reaction Solver in Verilog -- NO ODEs!
For a bimolecular reaction involving two molecules A and B, with concentrations [A] and [B] and a rate constant K, the probability of the reaction occuring (from mass action) will be K[A][B] . Assuming a time step which is short enough to make the probability...

FM-synth, two voice, Markov sequence, music box
Details from FM-synth, two voice, Markov sequence, music box
To synthesize nice sounding musical notes you need to control spectral content of the note, the rise time (attack), fall time (decay), and the change in spectral content during attack and decay. Also it is nice to have at least two independent musical...

FPGA Simulates Analog Computer
Details from FPGA Simulates Analog Computer
The general approach using DDAs will be to simulate a system of first-order differential equations, which can be nonlinear. Analog computers use operational amplifiers to do mathematical integration. We will use digital summers and registers. For any...

Spiking neural net in parallel FPGA hardware
Details from Spiking neural net in parallel FPGA hardware
We can use the FPGA to do fast numerical integration to solve differential equation models of neurons. This page describes a couple of neuron models and their solution by DDA techniques. Eugene Izhikevich developed a simple, semiempirical, model of cortical...

Low bit-rate Speech playback for AVR
Details from Low bit-rate Speech playback for AVR
DPCM (2-bit samples)A version of the DPCM algorithm can be implemented using very little processing time. A 2-bit/sample compressor/decompressor was written in Matlab to encode and to make a packed C header file, and then to do a test-decode. Note that...

Infrared serial link for AVR
Details from Infrared serial link for AVR
Full documentation at http://people.ece.cornell.edu/land/courses/ece4760...The receiver circuit is shown in the picture. The RC circuit acts a low-pass filter on the power to surpress spike noise and improve receiver performance. The RC circuit should...

DSP on 8-bit microcontroller
Details from DSP on 8-bit microcontroller
One of the most demanding applications for fast arithmetic is digital flitering. Atmel application note AVR201 shows how to use the hardware multiplier to make a multiply-and-accumulate operation (MAC). The MAC is the basis for computing the sum of terms...

Student AVR board
Details from Student AVR board
This page describes a prototype board for the Atmel Mega644 or Mega32 (PDIP) MCU. It includes a power supply, crystal clock, and generous bypass capacitors. A six-pin header allows flash memory programming from an STK500 or AVRISPmkII. All port pins...
