In plaats van Psoc4 pioneer gaan we nu de microcontroller STM32 NUCLEO-L4A6ZG gebruiken om eerst de ultrasoon sensor te programmeren en daarna de RGB LEDs aansturen.

We gebruiken STM32 CubeIDE als software om de STM32 NUCLEO-L4A6ZG kit te programmeren. Screenshot (98)

Eerst dus de MCU kiezen en dan het board (in onze geval STM32 NUCLEO-L4A6ZG) Daarna naar de main.c om de code te plaatsen. Screenshot (100)

ALi-Natiq commented 4 years ago

het is me nog altijd niet gelukt om het STM32L4A6ZG boord werkend te krijgen met ultrasoon sensor blijkbaar Omdat ik dit boord dat ik heb bestaat niet op de IDE van de STM software die ik heb. poz1

Ik heb al een gelijkaardig boord gekozen en daarmee geprobeerd te werken , maar ik krijg het niet werkend. poz2

Geprobeerd om gewoon een hallo world te sturen via de uart , maar het is niet gelukt. (Geen errors bij build of debug of run)
