Debugging an I²C bus with a PicoScope mixed-signal oscilloscope
Abstract
This application note describes how to debug an I²C bus controlling an Analog Devices AD5325 Quad DAC using a PicoScope mixed-signal oscilloscope (MSO). The MSO has two analog input channels, which are connected to the CH A and CH B outputs from the Quad DAC. The instrument also has 16 digital input channels. In this application only two digital input channels D0 and D1 are used, connected to the SDA serial data line and the SCL serial clock line of the I²C bus.
