Instek DS3-SBD Serial Bus Analysis Software
The serial bus trigger and decode software includes support for 3 common serial interfaces, SPI, UART and 12C. Each interface is fully configurable to accommodate a wide range of protocol variation.
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
