The STM microcontrollers clock synchronization using by three Nucleo boards

Patrik JACKO, Dobroslav KOVÁČ

Many devices operate with two or more microprocessors or microcontrollers, where the each chip has a specific function.

For example, one microcontrollers scans the input signal using by AD converters, the others microcontroller process and shows output data getting from another microchips. There must be insureed synchronization between microcontrollers for correctly communication and synchronization. This article describes clock synchronization of STM32F4 microcontrollers implemented on the Nucleo-64 development board, where one microcontroller operates as master and the other microcontrollers operate as slave.

Keywords:  clock synchronization, Nucleo64 board, STM32F446RE, STM32 microcontroller
