TV-based oscilloscope (with ARM7)

This TV-based Oscilloscope is based on a LPC2138 microcontroller application. It can be used to convert a standard television into a high-functioning oscilloscope.

Another Philips contest contribution. The main purpose of the project is to implement a high-resolution video generator inside the ARM microcontroller, LPC2318. In this case, the video generator is able to operate in the background mode, even though with a very low CPU loading!

The digital storage oscilloscope has a sampling rate of 160,000 samples per second and generates high-resolution video at 512 × 240 pixels. Neither a video controller nor extra RAM are required. Five different voltages on the five analog inputs can be monitored simultaneously.

It supports both NTSC and PAL.
