When your STM32 processor starts up from a reset, there are a number of possible sources for that reset. You may want to perform different initialisations depending on the exact source of the reset. A single register holds the flags which tell you why the processor was reset. It is…

It didn't take long to get the first Decimus 4 board on the bench for a build. This first one will serve as a static testbed for code development and sensor testing. After verifying that the power supplies were good, the LEDs, display, buzzer and pushbuttons were added for a…
