“There is a NTSC version with a 3.579545MHz crystal or a PAL version with 4.43618MHz crystal available. Pier 42 4x Video Display Shield Gives Your Arduino or Feather Board Four Composite Video OutputsĮlectronic engineer Wolfgang Friedrich has launched a display add-on for Arduino Uno and Feather form-factor microcontroller boards which give them an impressive four composite video outputs - complete with integrated frame-buffers for each. He used an AVR ATtiny85 to generate PWM waveforms which were picked up by his TV.” Replyīuilt around the VLSI VS23S040, this smart add-on offers four dedicated display outputs - complete with independent frame-buffer memory. “I searched online and I came across avr_vhf project. “I wanted to make a simple & cheap analog TV transmitter from parts I had lying around,” Seet explains of the project’s origins.

Student engineer Manzel Seet has demonstrated how to create a video output from a microcontroller’s general-purpose input/output (GPIO) pins with no external components - by using pulse-width modulation (PWM) to generate analog TV signals. Outputting a Video Signal From a Microcontroller’s GPIO Pins - Through Square-Wave Harmonics Taking advantage of higher-order harmonics, Manzel Seet’s PAL Streamer can output valid video signals from slower microcontrollers. Moved to ATMega328 platform (Arduino UNO Board)įirst thing noticed is that the image is perfectly stable using the crystal. The heart of the project is the ATMegaxx8Īfter failing with using the internal oscillator I have switched to Arduino Board as a prototyping platform. The circuit provides a video output with voltage and impedance according with the RS-170 standard.Ī CR2025 coin cell powers the circuit that it is automatically activated when the output plug is connected.

This project implements a low cost portable NTSC video pattern generator for testing monochrome video systems regarding gain and resolution. The entire circuit is powered by a coin cell, and the entire thing fits in a Tic-Tac box. He’s using it as a test pattern generator, pushing out pixels to any old TV. It does have its limits though there isn’t a whole lot of Flash, and of course you’re always going to need a few extra pins.įor his Hackaday Prize entry, is pushing whatever limits are left with the ‘tiny85. You get an Open Source toolchain, and if you’re really good, you can build your own programmer. In just eight pins, you get a microcontroller with just enough oomph to do some really heavy lifting. The ATtiny85 is an incredible piece of engineering.
