Asynchronous Serial and Terminal Emulator Support
Log from VGA Graphics Over SPI and Serial - VGATonic
Today, the ATTiny 2313a comes alive!Serial support (or, as I discussed today in the Hacker Channel, other names you might know it as - "Asynchronous Serial", "RS-232 TTL", "TTL Serial", etc.) was always on the roadmap for VGATonic, but my Terminal Emulator...

Introduction
Instructions from UART - Retrieve GPS Position
In this example, we use Adafruit Ultimate GPS Breakout. Its data format is pure text, so we can connect it to USB to TTL Adapter and observe the output.It follows the NMEA sentence format (refer to http://aprs.gids.nl/nmea/)The GPS signal is weak...

Bluetooth Remote Control Intelligent Smart Car
Details from Bluetooth Remote Control Intelligent Smart Car
At the beginning of the new year, robot/Smart Car hobbyists and students (like all of you) about engineering, science and technology are busy with preparing for the robot competitions now. It's the great time to show the world your imagination and potential...

Breadboard VGA from TTL and SRAM
Details from Breadboard VGA from TTL and SRAM
This is a follow-up of my "Breadboard VGA from EEPROM" project that was covered here [hackaday.com] two weeks ago.The video shows the new circuit's first signs of life. It is not really stable yet, but definitely getting somewhere. Halfway the build...

Arise's keyboard
Details from Arise's keyboard
Looking for components in PLCC package. XC9500 is dead and for new project you'd better go to XC9500XL but, since it's for hobby, I'd like to have both if possible.The datasheet reports that new XL are Pin-compatible with 5V-core, e.g. the XC9572 device...

Logic Implementation and Analog Simulation
Log from VHDL/Verilog to Discrete Logic Flow
Basic logic gate implementation The synthesis step transforms the digital circuit into a spice netlist based on logic cells. To complete the circuit and allow analog simulation we have to actually implement the logic on devices level. ---------- more...

Displays: How about Nixie Tubes?
Log from Star Trek: The Mirror Universe Pinball
I can’t claim originality here... as I remember the XENON machine at a past TPF which had NIXIE tubes instead of the standard VFD displays. I always thought they were cool. Now that I’m designing Star Trek: The Mirror Universe; I’m thinking that I want...

Usage Commands Found!
Log from Reverse Engineering Toshiba Flashair Wifi SD card
After digging through the data and extracting what I can from the firmware update file I found the following usage data.. It still needs to be cleaned up, but it does help to identify data on the device.Usage commands found in no particular order.. (needs...

sdramThing4.5 "Logic Analyzer"
Details from sdramThing4.5 "Logic Analyzer"
sdramThing was recently featured on the Hackaday Blog! Thanks Al Williams!SDRAM Logic Analyzer Uses An AVR And A Dirty Trick | HackadayNote that sdramThing4.5 (this project) has pretty much reached an end. The next phase is more of a peripheral--using...

Firmware hacking and adding new applications
Log from Camera badge for Supercon 2017
Firmware APIs These are not documented here, but in the globals.h include file. This avoids the need to keep this page synchronised with the current firmware version as features are added or modified. Tools required Microchip MPLABX (4.0x) and XC32...
