This single chip solution turns your TV into a digital storage oscilloscope with a sampling rate 160 Ksps. As a bonus, five voltages on the five analog inputs can be monitored.
No additional video-controller and video-RAM are required. Main goal of this project is an implementation of a high-resolution (512×240 pixels) video generator inside the ARM microcontroller, LPC2138. This video generator operates in the background mode, with a low CPU loading that allows the other high-intensive tasks (such as the data collection and visualization) be run.
Both of standards, American NTSC and Europe PAL are supported.
