Before you commit your design to an FPGA, you’ll probably want to simulate it. Debugging is much easier during simulation because you can examine everything. When the Verilog simulator runs, it follows rules about timing that take into account how everything...
The demo circuit has three distinct parts: the binary adder circuit from last time is already done. Another part of the example design is to provide an output that latches when a carry is generated. Here’s the part of the code that does that: reg...
Best Budget DIY GPS/GNSS Base Station using the UM980 and a ESP32Introduction The ESP32 is a versatile microcontroller renowned for its WiFi and Bluetooth capabilities. In this guide, we’ll walk you through setting up the your ESP32 development board...
(Note: now we are going to start working on the Adder. You can download the source from the file section or follow along in the online simulator). Verilog isn't executable in the same way that C or Python code is (except when it is). That’s...
At these clock frequencies, this technique of dividing down the clock is OK, but usually you'd rather use the FPGA's clock circuitry like a PLL or DLL to generate different timings, if possible. How you do this will depend on your FPGA and won't work...
First of all, create an account on Tuya Platform. Install tuyaos-link-sdk in Python. git clone https://github.com/tuya/tuyaos-link-sdk-python.git python -m pip install ./tuyaos-link-sdk-python Tuya IoT Platform(Web) Once logged in, create a...
DIY Onocoy Reference Station Setup GuideIn this guide, we’ll walk you through the process of setting up your own GPS Onocoy server using cost-effective hardware options and reliable GPS receivers. Whether you’re interested in enhancing the accuracy of...
The remainder of the Verilog takes the 12MHz clock and uses it to drive a 16 bit counter. When the counter overflows, another counter increases. When that counter reaches 91, the secondary counter goes to zero. This takes roughly 1/2 second at 12MHz....
This diagram shows what could be one of the simplest state machines possible. It operates a hypothetical air machine at a gas station. You insert a quarter and the air compressor turns on for a fixed amount of time. When the timer runs out, the compressor...
I first visually look for shorts/opens, especially on the QFN or QFP and USB (shorts can be easily reworked with the Kester 2331-ZX flux pen; always clean and dry boards after rework; I use isopropyl alcohol and a toothbrush followed by running water)....
Before mounting the prototype PCB to the housing, I recommend uploading the required sketch to the ATtiny84 microcontroller with a programmer of your choice. I used a USBtinyISP type shown in the picture. /*Sketch for the Scary Cat Project by Gene H*/...
Programming the finish switch Mega board)The finish switch Mega board will be the brains of the operation. It will come up with a 5 digit number to Serial communicate to the other boards. The 5 digit number will contain 3 pieces of information. The first...
Here are a few more-or-less random notes about 3D printing the calculator enclosure. I've printed it with the Creality Ender 3 V2 printer using PETG plastic, and the case went really well I think. Contrary to what's written in many websites,...
We have prepared a code for you so that you can move the spider robot without any problems at first. A few commands are ready in the code, but you can revise it yourself ;#include // include IR Remote library #include // include servo library //=====...
Clocks are an important part of practical digital design. Suppose you have a two input AND gate. Then imagine both inputs go from zero to one, which should take the output from zero to one, also. On paper, that seems reasonable, but in real...
