PC-Based Logic Analyzer - Intronix

The LogicPort provides 34 channels sampled at 500MHz. This includes two state-clock inputs which function as normal sampled channels in timing-mode. The LogicPort is controlled and powered via your PC's USB 1.1 or 2.0 port for the ultimate in convenience and portability.

The LogicPort's software includes interpreters for CAN, I2C, Synchronous Serial (SPI) and Asynchronous Serial (RS232) protocols. Its Synchronous Serial interpreter is very flexible and interprets 3-Wire, Microwire, PS/2 and other proprietary protocols in addition to SPI.

Feaures Include
  • Real-Time Sample Compression
  • 500MHz Timing-Mode (Internal Clock)
  • 200MHz State-Mode (External Clock)
  • Advanced Multi-Level Triggering
  • Built-in 300MHz Frequency Counter
  • CAN, I2C, SPI and RS232 Interpreters
Intronix is developing high-performance PC-based test instruments. They started as a ATE solutions provider. Automated test equipment and systems (ATE) are PC based Advanced T&M Interfaces.

EdSim51 - 8051 Simulator

A virtual 8051 is interfaced with virtual peripherals such as a keypad, motor, display, UART, etc. The student can write 8051 assembly code, step through the code and observe the effects each line has on the internal memory and the external peripherals.

EdSim51 - 8051 Simulator

The student can learn how to scan a keypad, multiplex 7-segment displays, control a motor and count its revolutions, etc.


A Note from the Developer - Jjames Rogers - ."While lecturing in electronics at IT Sligo, I searched the Internet for an 8051 simulator suitable for teaching but to no avail. I therefore decided to develop my own simulator for the basic 8051 with virtual peripherals attached to the four ports."

"After about a year's working on the project, on and off, the result was the EdSim51 simulator. I then put together a set of notes that are now the Beginner's Guide to the 8051on this website."

The Virtual Peripherals:
  • Analogue-to-Digital Converter (ADC)
  • Comparator, UART
  • 4 Multiplexed 7-segment Displays
  • 4 X 3 Keypad and 8 LEDs
  • DC Motor and 8 Switches
  • Digital-to-Analogue Converter (DAC) - displayed on oscilloscope
