Object of study – studying the principle of operation of the MAX31850 microcircuit. Analysis of the algorithms for connecting the OneWire interface to the microcontroller and choosing one of them. Implementation of the temperature reading algorithm from the MAX31850 chip. Implementation of the algorithm for sending data via the NLS transmitter. Purpose of work – to develop a program for STM32F042F4 to obtain the temperature of a thermocouple using the MAX31850 chip via the OneWire interface and send the temperature to the UWB transmitter. This paper discusses the development of a program for STM32F042F4 to monitor the temperature of a thermocouple from a MAX31850 chip via UART, pack the temperature data into fixed format data packets, and then send them to a UWB. To accomplish this work, a program was written that allows the STM32F042F4 to read the data from the OneWire interface of the MAX31850 chip via UART and convert it to a temperature value. The data is then packaged and sent to the UWB transmitter via the SPI interface.
