RE: control a DC Motor using MOTOR CONTROL PWM in LPC1768

Amir Hejazi

@ everybody(Erik, Per & ...)
it is very interesting for me to know how did you found that i am an electronic student???
and which school session, is finished at October (in my country)?
unfortunately internet is full of 'EXPERT TROLLs' instead of real 'engineers'.

    Hi
    another question
    I have doubts about LER in PWM.
    assume that:

    LPC_PWM1->MR0=1000000;
LPC_PWM1->MR1=500000


    and TC value is about 20 and it haven't been mached with 500000 !
    now if an interrupt occurs that contains:

    LPC_PWM1->MR1=200
LPC_PWM1->LER =0x01;


    does the match occurs for MR1=200 or the program runs the match for MR1=500000 and uses the new value (MR1=200) for the next cycle?

    thanks
