Programming an 8 digit 7-segment display, the easy way, using a Max7219

Allan Schwartz shows off the easy way to interface 7-segment displays using the MAX7219: Previously, in part 1 of my blog posting Programming a 7-segment Display, using just Arduino digital pins (the hard way) we had demonstrated how to hook up a pair of 7-segment displays to an Arduino, treating each individual segment as a […]

504 Segment clock, a 7-segment clock done differently

Bertho  has designed and built this cool 7-segment clock, the 504 Segment clock: At some point I was being silly and got the idea of making a 7-segment clock, but then a bit different. The result became this.  Features include: 72 7-segment displays in three rings; inner (hour) ring 12 displays, middle (minute) ring 24 and outer (seconds) ring 36 […]

Verilog project: Binary to 7-segment display

DJ Delorie was looking for an excuse to learn about Verilog and CPLDs. So he coded up this binary to 7-segment display converter. He provides links to the source code and says this project fits into the Xilinx XC9572 (the same chip used in our Coolrunner-II CPLD breakout board. You can get our XC9572XL dev-board […]
