friends :
after creating my own timer class i had to revisit StopWatch_Init() and StopWatch_Start() where i took a few ideas from
my code didn't work right on timer over-runs and i stared at the LpcOpen code until i noticed that the 31 bit mask had one "F" to few and afterwards my code worked
sample copied from LpcOpen
in StopWatch_Init() :
Chip_MRT_SetInterval(LPC_MRT_CH1, 0x7ffffff | MRT_INTVAL_LOAD);
in StopWatch_Start() :
return 0x7ffffff - Chip_MRT_GetTimer(LPC_MRT_CH1);
unless lpcopen has something else in mind, i consider it wrong it should contain 0x7FFFFFFF
it works for me now
cheers efiLabs
