Up to two different UART or I2C buses can be used at the same time. Only 1 SPI bus can be used at a time. Each input can be displayed as bi nary or hexadecimal. An event table can also be created to aid in debugging. Note that the Serial bus trigger an d decode software is an optional extra. An activation key is required to activate the software. A month trial demonstration is also available.

Serial Bus Overview

UART
Universal Asynchronous Receiver Transmitter. The UART bus is able to accommodate a wide range of various common UART serial communications. The UART serial bus software is suitable for a number of RS-232 protocol variants.

• Inputs - Tx, Rx, Polarity
• Threshold - Tx, Rx (±10V)
• Configuration - Baud Rate, Data Bits, Parity, Packets

I2C
Inter Integrated circuit is a two line serial data interface with a serial data line (SDA) and serial clock line (SCL). The R/W bit can be configured.

• Inputs - SCLK, SDA
• Threshold - SCLK, SDA (±10V)
• Configuration - Read, Write in address

SPI
The SPI (Serial Interface Peripheral) bus is fully configurable to accommodate the wide variety of SPI interfaces.

• Inputs - SCLK, SS, MOSI, MISO
• Threshold - SCLK, SS, MOSI, MISO (±10V)
• Configuration - SCLK edge, SS logic level, MOSI logic level, MISO logic level, word size, bit order
