Разработка программы снятия Ð´Ð°Ð½Ð½Ñ‹Ñ Ñ термопары при помощи Ð¼Ð¸ÐºÑ€Ð¾ÑÑ ÐµÐ¼Ñ‹ MAX31850

Abstract

Объект исследования – изучение принципа работы микросхемы MAX31850. Анализ алгоритмов подключения интерфейса OneWire к микроконтроллеру и выбор одного из них. Реализация алгоритма чтения температуры с микросхемы MAX31850. Реализация алгоритма отправки данных по ШПС передатчик. Цель работы – разработать программу для STM32F042F4 для получения температуры термопары при помощи микросхемы MAX31850 по интерфейсу OneWire и отправки температуры на UWB передатчик. В данной работе рассматривается разработка программы для STM32F042F4 для контроля температуры термопары от микросхемы MAX31850 через UART, упаковки данных о температуре в пакеты данных фиксированного формата, а затем отправки их на UWB передатчик через интерфейс SPI с помощью DMA. Для выполнения этой работы была написана программа, позволяющая STM32F042F4 считывать через UART данные интерфейса OneWire микросхемы MAX31850 и преобразовывать их в значение температуры. Затем данные упаковываются и отправляются на СШП-передатчик через интерфейс SPI.

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.
