Hello community, we're using a NUCLEO L476RG with an rotary button. Connected to PC15 the interrupt is not working, but selectable. It's enabled in settings NVIC and the button works on PB3 for example. But why not on PC15? With regards Julius

NUCLEO L476RG with MCP23S17 on SPI communication supplied with +5V not working. When Connecting to 3V3 working, but why?

Hello,we've connected A0-A2 and VSS with ground. VDD and RESET are connected to supply voltage (+5V).The system does only work with 3V3 not +5V, but we don't see the problem how it's not going to work with the higher voltage.with regardsJulius

Thank you for the replies.We changed to use the 3V3 supply, so we can use it.
