Logic analyzer for teaching
Dobrocký, Marcel ; Macháň, Ladislav (referee) ; Levek, Vladimír (advisor)
This bachelor’s thesis deals with a design of USB logic analyzer that will be used for teaching purposes in laboratory environment. The main purpose of the logic analyzer will be analysis of serial communication protocols most frequently used in embedded systems - UART, SPI and I2C. The analyzer can be also used as a debugging tool while designing all sorts of digital systems. In the first part of this thesis, the theoretical background of above mentioned communication protocols is explained. The next chapter deals with the process of signal analysis with the designed analyzer. It also contains a detailed description of the hardware module design. The last part deals with designing the microcontroller firmware and PC software, while explaining different applications of the analyzer in teaching.
