description: The object of the study is the decoding of PPM messages.Â The purpose of the work is to investigate the possibility of decoding a message with PPM using MK STM32G474RE. In addition to reviewing the literature on the topic of modulating, encoding, demodulating and decoding messages with PPM and PWM, a sinusoidal signal was generated with PPM, noiseproof coding methods were considered, after which a binary block self-correcting Hamming code was selected. After encoding, the message was transmitted and received using the MC, the FTDI hardware module and the built-in USART MC module, the signal was decoded and the original sinusoidal signal displayed on the oscilloscope screen was obtained. As a result of the work, modulation methods and coding and decoding algorithms were implemented, message transmission and reception were carried out using peripheral MC modules. Such tasks are most often solved with the help of FPGAs, however, MC are more affordable devices and have many necessary blocks and modules to carry out such tasks. This implementation can be used both in control systems of various devices and in working with UWB.
