= Simple Logic Analyzer for PC
|
|
|
|
|
|
The Simple Logic Analyzer (SLA) shown in figure 1 is a 8-channel
|
|
|
measurement device capable of analyzing TTL- and CMOS
|
|
|
logic signals.

The measured signal first passes an input buffer
|
|
|
which prepares the data for further processing. Communication
|
|
|
with the PC application as well as signal capturing is done
|
|
|
by a ATMega microcontroller. A standard RS232 interface
|
|
|
is used for transferring data between the hardware and the
|
|
|
GUI. This logic analyzer is able to sample at a maximum
|
|
|
frequency of 2 MHz. The PC application is only available
|
|
|
for windows operating systems. Schematics of the hardware,
|
|
|
the microcontroller firmware as well as the PC application are
|
|
|
open-source. The OpenLab Logic Analyzer has a communication
|
|
|
protocol decoder as an additional feature. Students will be
|
|
|
able to decode and generate SPI, I2C and UART data packets
|
|
|
in order to verify their assignments.
