Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
This link seems to identify the problem. An indeed tracing the error message back into the code shows that the ESP IDF i2c driver (see image for source file name) is expecting to be passed a clocks variable in the config structure from espruino jshardwareI2c.c
I am testing a fix which will need to be ifdef out for the idf4 build. It also involves handling the i2C speed that Espruino allows to be set in the I2C.setup function. PR to follow.
Im setting up a local clone of Espruino to test the builds (including ESP32 idf V3) after the change to be sure the ESP32 old version still builds and executes I2C.
