Re: uln2003 pic
can you share your circuit even i am doing the same thing ,i want to use internal ADC want to convert negative voltage also ,i am driving 25 LEd's thoght to connect directly to pic pins but for that i need to select LED's with less current so i gone for ULN2003 ,but how you...
interrupt problem ??
I have idea that it will work when i cotrol outside but i am not getting with only the value 44h which we assaign to INTCON2 to tell interrupt occured . so every time it execute it tells that interrupt occur , after disabling also it will be in main routine so .
interrupt problem ??
ya i have checked by the pin polling and it is working fine only problem with interrupt part .. i have assained INCON2 as 44h and their it goes to ISR as i am writing that after the main it will take TX correct only but when i back to RX again that interrupt instruction...
interrupt problem ??
Hi all..
I am using external interrupt,when i set INTCON2 as 44 and INTCON as 92h it will go to the subroutine where i want TX operation to be done and when it release it does rx operation but problem is tx_operation data it is sending correct but when i go to rx operation...
ya sure.. actually i was dividing frequency with BW , BW is constant , i wanted to take the result value in my code , but what i thought instead of calculating it in code i can create one GUI their i will enter frequency and BW also their i can divide just i have to take that value in the main...
Hi all.. I am doing a program for analog radio so i need to take care of the below steps..
1.Rotating BCD SWITCH (KNOB)0000 to 1111
2.GOTO PERTICULAR CHANNEL
3.STORE THE INITIAL DATA
4.Interrupt PTT
5.If 1 go to TX data to calculate else RX data to calculate
6.RETFIE
7.go for channel changing...
actually i am entering frequency in GUI .. it is a variable that i am taking into my code ..and dividing it by 25k that is constant for all freq .. math equation only
ya it will take lot of space thats why i want to put it in a single formula kind thing.. just i enter the frequency in GUI .. In my code i need to calculate N value.. so anyway bandwidth is fixed so i wll store it and whenever i enter frequency it should divide by BW so.. is their any option to...
Hi all...
If i enter the frequency through GUI(graphical user interface) and with that frequency i want to calculate some other value that i am going to use in my code .
ex: i am entering frequency 400.125MHz and band width=25kHz
so i need to calculate N value
i.e N = 400.125MHz/25kHz
=...
Re: PIC18F assembly
ya its not a joke ??
Added after 2 hours 31 minutes:
i tried it but after shifting 10 times we will get 1F and 26 in MSB and in LSB respectively.. but the result should be F so where it will be??
