Announcing the ‘Shutter Pod’ project

The goal of the project is to design a timer for SLR cameras capable of taking long exposure and time lapse photography. At the heart of the  device will be a ATmega micro-controller and a 16×2 back lite LCD display. The entire project is being developed as open-source hardware and software being hosted on Google [...]

Verilog: Dual Seven Segment Display Driver

This is an expansion upon my SevenSegmentDisplayDriver module which will allow you to drive a dual seven segment display, specifically the add-on for the Spartan 3E but it should be quite easy to modify for other FPGA’s. The basic premise of this module is you have a dual seven segment display which activates the left [...]

State Machine for the Spartan 3E Knob

The following code is a simple state machine that determines the direction that the knob on the Spartan 3E is turning and outputs a clock signal (Count) as it turns. A & B are the inputs from the encoders on the knob, RST & CLK are the reset and clock obviously. Count is the clock [...]
