Enhanced bilnky does not Work

I tried to set up an enhanced blinky with following installed Frameworks My frameforks are: ########################################################################## contrib-piohome framework-arduino-avr-microcore framework-stm32cubef0 tool-openocd framework-arduino-avr framework-arduino-avr-mightycore framework-stm32cubef4 tool-scons framework-arduino-avr-attiny framework-arduino-avr-minicore tool-avrdude tool-stm32duino framework-arduino-avr-bean framework-arduino-avr-nicai [email protected] toolchain-atmelavr framework-arduino-avr-digistump framework-arduino-avr-panstamp tool-cppcheck toolchain-gccarmnoneeabi framework-arduino-avr-dwenguino framework-arduino-avr-prusa_rambo tool-dfuutil [email protected] framework-arduino-avr-majorcore framework-arduinoststm32 tool-dfuutil-arduino framework-arduino-avr-megacore framework-cmsis tool-ldscripts-ststm32 ################################################# I try to run following code: ############################################ #include <Arduino.h> #include <wiring_digital.h>

The button does make any effect. It seems, that it can not be read. The docu can be found here: I use a Nucleo-L476 (https://www.st.com/content/ccc/resource/technical/layouts_and_diagrams/schematic_pack/group2/74/18/73/70/3c/70/4a/52/MB1136-DEFAULT-C04_Schematic/files/MB1136-DEFAULT-C04_Schematic.pdf/jcr:content/translations/en.MB1136-DEFAULT-C04_Schematic.pdf, https://www.st.com/resource/en/user_manual/um1724-stm32-nucleo64-boards-mb1136-stmicroelectronics.pdf). The soulution with removing the "_" claimed as my solution does not work. I see the same Error with a [env:nucleo_401rg]. Original Posting is here: See my problem in https://community.platformio.org/t/enhanced-blinky-with-button-and-led-does-not-work/37375 I tried to control the LED (PC_7) on the x-NucleoS2686A2 but the led can not be lit.
