Previous blogs: FPGA: Making Waves FPGA: Waves 2: Simple Sinewave   Introduction   I have a small Brevia 2 development board [1] from Lattice Semiconductor featuring one of their XP2-family FPGAs. I'm using it to explore, in a very simple, basic kind of way, digital signal generation and processing. This isn't a tutorial, just me experimenting and trying things out. In the last blog I used one of the block memories in the FPGA as a look-up table in order to generate a sine w ...
FPGA is fun and easy to learn. Interfacing of Digilent Cmod S6 FPGA development board with 7 segment display. In this code 7 segment display is directly connected to FPGA but it can also be connected through BCD to 7 segment decoder to minimize the number of IO pins.   Demo:   Important Links: Cmod S6 Schematics: cmods6_sch.pdf Master UCF file: cmod_s6_master_ucf.zip Factory Loaded Example: cmods6_demo.zip Reference Manual for Factory Loaded Demo: reference-manual VHDL Syntax f ...
FPGA: Making Waves   Introduction   I have a small Brevia 2 development board [1] from Lattice Semiconductor featuring one of their XP2- family FPGAs. I'm using it to explore, in a very simple, basic kind of way, digital signal generation and processing. I'm using VHDL to describe the digital logic that I'm designing. In the last blog I described a simple circuit using a low-cost 12-bit SPI DAC from Microchip, an MCP4821. I tested it by throwing together some VHDL to drive the D ...
A couple months back, I decided to buy an Avnet Ultra96 V2 board and make something interesting.  The Ultra96 is a compact, inexpensive platform with some amazing capabilities. https://www.avnet.com/wps/portal/us/products

FPGA: Making Waves

Posted by jc2048 Sep 1, 2019
    Introduction   I have a small Brevia 2 development board [1] from Lattice Semiconductor, with one of their XP2-family FPGAs on it, that I bought from Farnell a while back. Last year I got as far as doing these two blogs before getting distracted and going off in quite different directions.   Booards and Boojums: Lattice XP2 Brevia2 Board: Part 1 Booards and Boojums: Lattice XP2 Brevia2 Board: Part 2: Count Those LEDs!   It's time to have another play ...
