MAX31856 STM32 Example Quick Start
This firmware demo communicates to a MAX31856 Precision Thermocouple to Digital Converter through
SPI and outputs the temperature measurements through the UART of an STM32 Nucleo development
board.
Hardware Required
• Computer with available serial port to monitor serial output of the development board.
• STM32-Nucleo with STM32F103 (purchase separately)
• MAXREFDES72#--- Pmod Adapter for Arduino Platform (purchase separately)
• MAX31856EVKIT—Pmod board. (purchase separately)
• USB cable (purchase separately)
• A wire to connect CN3 RX to Jumper D8.
Software Required
• IAR Embedded workbench
• Tera Term for serial communication from PC to development board
