Error compiling for NodeMCU in Arduino environment

[AlexZibin]

Hi,

The Arduino compiler reports the following error:

Documents\Arduino\libraries\SoftwareWire\SoftwareWire.cpp:146:16: error: cannot convert 'volatile uint32_t* {aka volatile unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment
   _sdaPortReg  = portOutputRegister(port);
                ^
Using library SoftwareWire at version 1.4.1 in folder: Documents\Arduino\libraries\SoftwareWire 
Using library Rtc_by_Makuna at version 2.0.2 in folder: Documents\Arduino\libraries\Rtc_by_Makuna 
exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module).

Compiling for Arduino Nano goes correct without any errors.

Please help to compile for NodeMCU without errors, thank you in advance!

Thanks, that is indeed not implemented. The registers and bits are stored as 8-bit variables for the AVR family microcontrollers. The ESP8266 has registers of 32 bits.

The Wire library for the ESP8266 is already a software Wire library. Why did you change to this one ?

The most compatible library is the SlowSoftWire. That is a wrapper around another library, so you need both. Those libraries use only normal digitalWrite() and digitalRead().

Thank you for prompt answer!
