error: cannot convert 'volatile uint32_t*' to 'volatile uint8_t*'

Problem

../libraries/ADS1231/ADS1231.cpp:33:13: error: cannot convert 'volatile uint32_t* {aka volatile unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment
         out = portOutputRegister(ADS1231s[this->ADS1231Index].sclPort);

Solution

ADS1231.h

#ifdef __SAM3X8E__
  typedef volatile RwReg PortReg;
  typedef uint32_t PortMask;
#elif defined(ESP8266)
  typedef volatile uint32_t PortReg;
  typedef uint32_t PortMask;
#else
  typedef volatile uint8_t PortReg;
  typedef uint8_t PortMask;
#endif

ADS1231.cpp

-volatile uint8_t *out;
+volatile PortReg *out;
