This make the communication not byte to byte controlled as I want it to be for my need. I realized that if I wanted to make an Arduino slave, when receiving from master, it actually reads from a buffer that is already previously received. But let’s start with the problem found in the Wire. When the limitations were somehow fixed, even though the small number of modifications (it is somehow a sort of hacking of the library) I found that the my final result were so useful to me that I thought was worth to write a short article about it. If you want to use other pins, when using the wire library. Then, when experimenting with a portability of a project in the Arduino environment, I started to trying the official Wire library, discovering some incompatibilities for my needs. When using the ESP32 with the Arduino IDE, the default I2C pins are: GPIO 21 (SDA) GPIO 22 (SCL). Any advice gratefully received.I have spent a lot of time on playing and later working on the I2C buses. I almost always used self developed libraries, both for learning and job requirement purposes. I'm unclear whether this is a Windows 10 issue, or if it's caused by something residual on my PC. I've tried IDE 1.8.4 on a Windows 8.1 machine - all works fine. I've repeatedly removed all Arduino directories from my PC (running Windows 10) and re-installed. The structure of the Wire library looks fine (though I'm puzzled that there are 2 twi.h files in the hardware\tools tree, in addition to the one in Wire\src\utility). In the IDE, neither the boards manager nor the library manager show any errors. On-line references to this error are fairly old, and refer the problem having been solved - I've been unable to find anything relevant. (make no difference which board selected) Library can't use both 'src' and 'utility' folders.ĭouble check C:\Program Files\Arduino\hardware\arduino\avr\libraries\WireĮrror compiling for board Arduino. Even an empty sketch which includes Wire.h fails. I recently updated from IDE 1.6.2 to 1.8.4 and am now unable to compile any sketch which includes the Wire library.
