Hi everybody,
I'm working with LPC1227 and LPCXpresso and i got the CT16B1 working successfully as PWM.
When i have started taking a look at current consumption i have realised that something weird is happening.
When i set the match register as follows, before running the last line the current is about 60mA, and after running it the current dropes to 7 mA more or less. Why is that?
Can anybody help me?
/* Setup the match registers */
/* set the period value to a global variable */
timer16_1_period = period;
LPC_CT16B1->MR3 = timer16_1_period;
LPC_CT16B1->MR2 = timer16_1_period/2;
LPC_CT16B1->MR1 = timer16_1_period/2;
LPC_CT16B1->MR0= timer16_1_period/2;
Thanks and best regards.
Alberto
