Some idea? Should I use a different library? Are there any known issues with ESP 32 and the WIRE? Through the serial line, only the variable x of the Loop is updated with the print of the zero previously assigned, but not updated by the receiveEvent(int howMany). The instructions work perfectly between NANO and ESP 32 using only the WIRE and eliminating the use of other peripherals that use I2c NANO has to send data of a variable (x in my case) through I2cĮSP 32 must receive data with I2c using WIRE libraryĮSP 32 connected with I2c a 24x4 LCD displayĪll services with I2c work fine without WIRE libraryĪs soon as I insert this into the project, there is no transfer between the NANO and the ESP 32. Result I have no data transfer between the two processors LCD does not work and BME 680 is not recognized. I have a little big problem in my project where I'm using different libraries that work great without conflicts with each other.īut now I have to transfer variables between a NANO and an ESP 32 38 pin using the WIRE library through I2c.
