Getting Started with Infinite-ISP, the open source image signal processor on Efinix Titanium Ti180 J484 Development kit.
This project walks through how to implement a simple FIR filter with pre-generated coefficients in Verilog.
Filters are a key element of FPGA based solutions lets look at how we can create a FIR filter and interact with it in PYNQ!
Application notes for Pmod MIC3 and Arduino Uno. In this app, the sound captured by the module is displayed in the serial plotter.
Using the ADP3450, this project measures amount of delay between asserting FPGA IO on base of NPN 2N3094 and LED illuminating on collector.
Getting Started with Infinite-ISP, the open source image signal processor on AMD Kria KV260 AI Starter kit.
Light up three different LEDs using pulse width modulation corresponding to different ranges of analog input voltages.
NanoVNA is a useful tool in telling if an antenna is a good one or not. We maximize our range and hence rewards by using the best antenna!
This project is WiFi Oscilloscope with network volt meter arduino source code for esp8266 and esp32 WiFi modules + a nice web application
FPGAs / SoCs are great for signal processing. Let's take a look at how we can implement a test platform for experimentation.
Build an analog theremin using only the Analog Discovery 2, the Digilent Analog Parts Kit, and your choice of an empty beverage can!
