description: Object of study is â Ultrasonic modem software code. The aim is â Development of a program code in C language for the operation of an ultrasonic modem based on the stm32 microcontroller. This work uses the orthogonal binary frequency shift keying (BFSK) modulation method, non-coherent detection method, and frequency hopping spread spectrum (FHSS) technology to improve the communication reliability, optimize data transmission, and reduce the bit error rate. The software architecture and communication interface use The multi-layer architecture uses microcontrollers and the signal generation and processing of DAC and ADC to ensure the accuracy and efficiency of signal processing and other solutions, improve the stability and reliability of communication, and optimize the performance of the modem. This study covers the entire communication process from signal generation and transmission to reception and processing. Modems are not only suitable for underwater sensor network monitoring, but also play an important role in areas such as pollution source tracking, water quality detection, and disaster response. Open educational resources and programs for searching and analyzing information were used. STM32CubeMX automation (automated) development tools were used. Keil uVision 5 software was used (tested).
