    [AVR] confuse to displaying the average adc value using codevisonavr

    buffer in at an array and than take the average... like int i ; long sum = 0; for(i = 0; i < "your Limit say 50"; i++) array[i] = read_adc(); for(int x = 0; x < i; x++ ) { sum = array[x] ; } average =sum / i; i think This Do.... I hope

    [Moved] ATMEGA 8515 Port Pins Read

    Hi To Read pins in AVR you can use PINX--- where x may be A,B,C or D etc. this is for hole PORT read... you can read individually by using PINB0 // for 1st pin in port b PINB1 // for 2nd pin in port b also for check the status of the pin you can use if(bit_is_set(PORTB,0)) { } Hope...

    Is it possible to have two Baud rates in 89S52?

    HI Jeffrey Peter I don't think you can do this... say you built 2 different routine to set the Baud rate ... the problem may be accores like ... when you are sending something at that time if there is some data cames to read then... ok try to do this but don't use the interrupt method...
