SCANALOGIC-2 is an educational kit that allows you to build a low-cost four channel logic analyzer at home. It is based on ATMEL’s Atmega168 microcontroller. It connects to a PC through USB port and uses a free PC software called ScanaStudio to visualize and analyze the captured signals. The key features of SCANALOGIC-2 are: Sampling rate: 20 Million samples per seconds No. of channels: 4 Memory depth: 256K per channel (total 1 MByte) Protocol decoding: I2C, SPI, UART, 1-Wire Digital output capability: PWM, FM, UART packets Logic analyzers have two basic modes of operation: timing mode and state mode. In timing mode, the data is sampled at regular intervals according to a clock internal to the logic analyzer. As such there is no fixed timing relationship between a target system and the samples acquired by the logic analyzer. The samples are stored in the memory and are used later to analyze the timing relationship between the signals. This mode of operation is also known as asynchronous acquisition and is useful in debugging mostly hardware problems. The timing relationship between the signals is not particularly useful while tracking down software related problems. The software developer is more interested to see the instruction flow of the program. In state mode, a signal from the target device (usually a microprocessor clock) defines the sample point. Signals are captured on the active edge of every clock signal received from the target device. In this case, the relative timing information between the signals is unimportant. Since the data are sampled during the active edge of the system clock, the logic signals are stable and represent a valid state of the target system. Therefore, with multiple samples, it is possible to capture and display successive states of the system in a sequence. This points up the major difference between timing and state mode. The timing analyzer has an internal clock to control sampling, so it asynchronously samples the syst
