You need to explicitly cast the third argument ( 400000) to uint32_t in order to tell the compiler which of the two functions you want to call: Wire. ![]() For me it happened specifically when upgrading to arduino-esp32 version 2.0.1. C:Usersuser-2DocumentsArduinoArduinoSTM32STM32F4librariesWireexamplesi2cscannerhardwirei2cscannerhardwire.ino:29:18: fatal error: Wire.h: No. The Arduino Wire library is according to the I2C standard. ![]() The I2Cdev.h header also includes it if necessary. arduino/ArduinoCore-megaavr83 commented Relying on this timeout for proper 1 matthijskooijman commented if there are bus lockups or other problems, that you should not just enable timeouts and except it to make things run properly. I think that it is not possible that it has to with the symmetry of the clock signal. If youre using the Arduino Wire library, make sure you include Wire.h in your main sketch file. Wire library has no timeout functionality (meaning it is blocking). This happens with specific versions of the Arduino framework.
