[InfoShortDescription.en]
Simple low frequency oscilloscope project. The project utilizes modules ATMEGA801B, USBRS232R01B and ADCmonoSPI01B.
[InfoShortDescription.cs]
Jednoduchý nízkofrekvenční osciloskop. Využívá modulů ATMEGA801B, USBRS232R01B a ADCmonoSPI01B.
[InfoLongDescription.en]
The device services for analog signal conditioning, ADC sampling and raw data transfer to PC. Following processing is taken on the PC side.
[InfoLongDescription.cs]
Zařízení provede zákládní zpracování signálu analogovou cestou, navzorkuje daný počet hodnot a odešle je osobnímu počítači. Další zpracování provádí software PC.
