Building an Analog Oscilloscope Companion

Circuit Cellar is pleased to present Greg Cloutier's LPC2138-based ARM Scope which improves upon ordinary analog oscilloscopes that don't provide suitable results at low speeds. This system features a timed PWM output for the more precise calibration of the oscilloscope as well as an analog input and an analog output with a graphical display. As a result, the displayed signal is more accurate at high or low speeds.

Greg used the Keil MCB2130 as his target hardware platform.
