I changed the name for "STM32F1.ino" to "STM31F1_LogicAnalyzer.ino"

Was it working before you changed the name?
Which stm32 core did you installed?

[samigroup]

The name change has nothing to do with it,
I used STM32F103 (Blue Pill).

[aster94]

Please answer the second question: Which stm32 core did you installed?

[samigroup]

1# Arduino STM32F4 Boards by Arduino ver 1.0.1
2# STM32 Cores by STMicroelectrnoics ver 1.6.1

[aster94]

ok, please read the information in the sketch, you are using a different core https://github.com/aster94/logic-analyzer/blob/master/Microcontroller_Code/STM32F1/STM32F1.ino

even though i would like to move to the STM32 official core now i don't have time to do this
