Summary of Monochrome Composite Video using Atmega8
This article explains a Text on TV project that uses an Atmega8 microcontroller (16 MHz) to convert serial data into monochrome composite video for TV display, detailing PAL and NTSC timing and how to implement the video signals in software.
Parts used in the Text on TV project:
- Atmega8 microcontroller
- 16 MHz crystal
- Serial data source (e.g., UART connection)
- Composite video output wiring/components (to connect to TV)
- Power supply for microcontroller
- Support components for microcontroller (e.g., capacitors, resistors)
This article describes the design of a Text on TV project. It takes serial data and displays text on a TV screen. The hardware part of this project is pretty simple. It uses an Atmega8 microcontroller that runs with a 16 MHz crystal. The article provides the details on PAL and NTSC timing signals, as well as how to implement the signals in software.
