interrupt routines for pic18f4520
Thanks all for the reply. The problem was because of high initial context saving. The hi-tech c compiler was using a lot of temperory variables in the assembly equivalent program. To save all these variables a large amount of time was being spent. so we have...
pic18f4520 registers
Hi,
Thanks for the reply.
There is a particular reason for selecting the clock frequency and it can not be changed.
The CCP2 interrupt is having highest proirity.
I am using MPLAB IDE Version 7.6 and Hi-Tech PICC Compiler Version 8.53 PL3.
I think it is necessary to put a...
frequency input for pic18f4520
Hi,
We are working on PIC18F4520 micro controller with an external oscillator of 22.1184 MHz. We are using CCP2 capture interrupt which will capture a falling edge at the CCP2 pin input. The ISR for the CCP2 module will be called once the falling edge occured...

iic slave mode
Hi,
I am working on PIC microcontrollers currently-dsPIC33F256GP710. I want to work my PIC as a slave device for I2C communication. I have done the initialization part only till now.
If any one have the code for I2C slave mode for any microcontroller please upload here or...

Hello,
I have got a piece of assembly code of Motorola 68HC05P1/P9 microcontroller.
I have found out the meaning of different instructions from the datasheet.
Now i need to find out the meaning of statements like:
1. IR_Input equ !5
2. T_500 equ $A2
3. Key0...
Thanks. But I could not down load the datasheet. When ever i click on the link , i get the screen which says :

need the datasheet of MC68HC05P1/P9 microcontroller. In the net i could only find the datasheet of MC68HC05P18A microcontroller. Is this a version of the MC68HC05P1 controllre?
If yes, is there only this one version in which MC68HC05P1 is available?
I could not...
Hello,
this is very urgent for me
I am trying to burn a code in mc9s12c32 using code warrior IDE av3.1 and P&E USB Multilink interface.
The interface is recognized correctly.
when i tried burning the program, i got error mesaaage:" Error while loading dianostic algorithm to target system.The...
hi,
there is an issue came up during my project. please help me.
we have decided to use the microcontroller PIC24HJ256GP610 for our project. for this micro do we really need MICROCHIP REAL ICE for debugging?? will ICD2 alone will do? what is the diofference between the working of REAL ICE and...
if any body has got any tutorial for beginning the PIC micro programing please upload here.
if u have any code examples also plz plz plz upload here
language:embedded C
PIC version : 18F2420
thanks and regards,
