ATmega128 compilation errors with example GatewayW5100 sketch

wagi

Hello,

I'm working on GatewayW5100 example sketch. When board is with ATmega328P or ATmega2560 it is ok, but with ATmega128 board there are errors during compilation. Tested on ArduinoIDE and on PlatformIO.

Do you have any ideas what to do for repair or workaround ?

Welcome to the forum @wagi
The MySensors library is not aware of the atmega128. You’ll either need to add support (yourself or someone else), or use a board that MySensors is aware of.

We can see the problem is with MyHwAVR.cpp, where was not declared somethings when board is ATmega128.
But deeper is MyHwAVR.h, and has included wdt.h. There are this definitions:

#define wdt_reset() __asm__ __volatile__ ("wdr")

#ifndef __DOXYGEN__

#if defined(WDP3)
# define _WD_PS3_MASK       _BV(WDP3)
#else
# define _WD_PS3_MASK       0x00
#endif

#if defined(WDTCSR)
#  define _WD_CONTROL_REG     WDTCSR
#elif defined(WDTCR)
#  define _WD_CONTROL_REG     WDTCR
#else
#  define _WD_CONTROL_REG     WDT
#endif

#if defined(WDTOE)
#define _WD_CHANGE_BIT      WDTOE
#else
#define _WD_CHANGE_BIT      WDCE
#endif

#endif	/* !__DOXYGEN__ */

I've noticed, that when compiling good-working boards i.e. ATmega2560, we have defined WDP3, WDTCSR and WDTOE is not defined. But when compiling ATmega128 board we have NOT defined WDP3, NOT defined WDTCSR, but defined WDTCR and NOT defined WDTOE.

I'm not programmer, but I suppose, maybe in MyHwAVR.cpp there should be used the new other defined here constants. What do you think ?
