error: invalid conversion from 'int' to 'WiringPinMode' [-fpermissive]

[elmarfaber]

Hello,
I try to use the bounce2 under STM32 arduino code and get the following error:
.platformio\lib\Bounce2_ID1106\src/Bounce2.h:188:26: error: invalid conversion from 'int' to 'WiringPinMode' [-fpermissive]
I use VisualStudioCode with the PlatformIO extension.

Best regards
Elmar

Hum, it seems that the platform you are using defines pin modes as an enum.

This is a similar issue: https://www.stm32duino.com/viewtopic.php?t=463&start=20

I do not use PlatformIO yet. Sorry I can not help with this right now.

invalid conversion from 'int' to 'WiringPinMode' [-fpermissive]

This is not VS/PlatformIO issue. This is result of conversion of the Arduino Wire library to STM32 ( some company originally, stm32duino nowadays).
In original Arduino function is declared as:
void pinMode(uint8_t pin, uint8_t mode) Whilst in stm32 version ( STM32 io.h ) it is defined for Hell-known reasons as:
void pinMode(uint8 pin, WiringPinMode mode) Obviously code in Bounce2 targets traditional Arduino Wire API.
For your issue -- just copy void pinMode(uint8 pin, WiringPinMode mode) implementation, but change param to uint8_t and do corresponding changes in implementation to parse byte instead of Enum.
It's few hours work with testing and watching new series of GoT in parallel :).

Hi, there is already an #ifdef in Bounce.h at line 184:

#if defined(ARDUINO_STM_NUCLEO_F103RB) || defined(ARDUINO_GENERIC_STM32F103C)
        pinMode(pin, (WiringPinMode)mode);
#else
        pinMode(pin, mode);
#endif

Could you please add your test case and see if it compiles?

Maybe a more generic #if defined would be better.
