What's On the I2C Bus?WeatherPi makes extensive use of the I2C bus on the Raspberry Pi.At SwitchDoc Labs, we love data. And we love I2C devices. We like to gather the data using lots of I2C devices on our computers and projects. Project Curacao has a...
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...
Installing Firmware via an SD CardFor this first part of the tutorial we are going to be using a firmware that demonstrates a couple of buttons, a progress bar and a text field.In the firmware folder in the library you will find the .tft files:2.4" Nextion...
Choose your color pairsWe will use one color for each nucleobase. Remember that nucleobases go in pairs, and that the only possible pairs are adenine-tymine and guanine-cytosine, so if you don't want your annoying bio-engineer friend to make sarcastic...
During your normal Arch installation you usually come to the point where you install the bootloader. In most cases either GRUB or systemd-boot. We will install GRUB.For the following commands I assume, you have arch-chroot ed into the installation.I...
Simple setup, place your camera on a tripod, your Moiré pattern right next to it and focus the camera onto the pattern. 82 cm is a good distance in between the camera and the pattern.For my camera a aperture of f/4 with auto-gain and a shutter of...

To make a Green BMS system, you have to install the following Open Source Applications: Arduino IDE (download page) Libre CAD 2d (download page) To perform hardware modifications on project, you need the following Open Source Applications: Kicad (download...
moThe big black device in the middle of the printed circuit board (PCB) is the speaker (aka buzzer, or transducer). You can see a little slit in the one side where the sound comes out. There is a back side to the circuit board that you cannot easily...
Arduino Mega Code The code in the main control panel is fairly standard except for the part which sends data down the I2C bus to the Adafruit Feather slave. This code can be found in 'void sendData()' below and involves disassembling complex float numbers...
(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...
In order to get the Waveshare to display properly you will need to edit the config.txt. To do so, open the terminal and type: sudo nano /boot/config.txt You will need to add the following: # 1920x1080 monitor (0 means monitor 1 the outside most hdmi...
