Hi Guglielmo!

Try this version of the code:

	static void begin() __attribute__((always_inline)) { 
		uint8_t btmp = PMCR |  (1 << RCMEN);   // 0000 0001 (enable RCMEN)
		        btmp = btmp & ~(1 << RCKEN);  // 1111 1101 (disable RCKEN)
			btmp = btmp & ~(1 << WCLKS);  // 1110 1111 (select HFRC)
		PMCR = (1 << PMCE);  // 1000 0000
		PMCR = btmp;
	}

Hi, thanks, this is actually the correct way to write what I wanted to do. :-D

Unfortunately, however, the result does not change and the WDT continues to operate following the LFRC :-(

ATM I don't have time to test but here is an another idea:

.
.
.
#include <WDT.h>

LGTWDT Lgtwdt;

void setup() {
    Lgtwdt.begin();
.
.   your code
.

This seems to be the solution ...
... by explicitly calling the begin() method, everything seems to work. Thanks for your help !!!
