This Logic Analyzer project allow you to monitors and captures a number of digital signals. It uses PC to display the data processing. The system consists of ATmega88-20PU AVR microcontroller as main processor and some simple components used for the interfacing with the PC, the man and the probes.
When you build a digital electronic project and have trouble with it you need a device to debug it. To analyze logic output from your project you need a Logic Analyzer. If you don’t have it you can try to build by yourself cheap logic analyzer device using parallel port. The device only use [...]
This is simple low-cost logic analyzer. The PIC18F252 board has function as capture device and display the result to PC. In Normal mode the max sample rate is 2 microseconds although the sustained rate is limited to 170 microseconds/event (RS232) of 40 microseconds/event (USB). In Fast mode the max sample rate is 200 nanoseconds, 4bit [...]
