Signal monitoring and waveform analysis play a significant role in state-of-the-art signal processing and electronic measurement. Traditional oscilloscopes tend to be heavy and huge, which makes it impossible for outdoor signal measurement. In addition, most of those oscilloscopes can measure merely two signals simultaneously. This article proposes the design of multi-channel digital oscilloscope over common Android mobile device. In our system we use STM32 development board to implement up to eight input channels, data processing and wireless transmission. In addition, an Android application is designed for Wi-Fi data reception, respective waveform demonstration and derivation of each signal’s amplitude and frequency. In order to transmit up to eight digital signals simultaneously as fast as possible, we designed an algorithm where all signals’ data can be transmitted within a surprisingly small amount of wireless data. In our system test, wireless data transmission is implemented and each waveform can be recovered and demonstrated basically. |
