well... two anyway.
PIC16F have a single interrupt vector so if you want to prioritize interrupts you have to do it in software. pic18f series have two interrupt vectors although you can still use just one if you want. The high priority interrupt can itself interrupt the low priority one but if you want other priorities you still have to implemen

You mean you will get the value of flag from that address? Yes, it can be accessed at runtime. How come pic18f device comes under C32 Compiler?

Hi .. everyone i am using pic18f microcontroller.
i have to build a system which response in real time manner.
so please guide me how multitasking can be performed by MCU and what is standard algorithm of software behind multitasking

friends, i have a pic development board. whenever i want to program it, i do it through the usb of my pc as a bootloader program is already there...may be the manufacture of the board is responsible for that. i want to enter a program's hex code and store it into micro-controller's program memory and through one of the ports of the micro-controller

I heard that PIC16F ADCs are not efficient and reliable.
Is that true ?
I am using PIC16F877A for my project.
Input to the ADC is sine signal with frequency between 0.5 to 4 Hz.
Should I need to use pic18f ?

i want to communicate 2 pic18f micro controllers using CAN protocol and i wrote a software for each of them
if i want to simulate it by proteus software how should i connect the cantx and canrx nodes?
does anybody have an example program for can protocol in pic18f??
if i want to get started with CAN, does anybody know which site

i find C18 MPLAB with MPLAB IDE 8.89 perfect for pic18f familly .. because free of charge and usefull librairy existing..
but not concern with PIC12F or PIC16F..
so i am using MikroC , free version up to 2K programm for PIC12F , very good libraries.
Problem is for PIC16F and program upper 2K size ..you must buy a licence 250$ !! to

Well to start with my project requires Data Logging , so i used a SDHC card interface PIC18 with SPI, and i can write raw data, no probs... but of course post logging analysis in WINDOWS is not possible, so I wrote a basic FAT32 implementation in ASSEMBLY, that does the following
1) Reads MBR and gets necessary Values for LBA calcul

I work on a project with pic18f, and there are some very important variables in my program. The values of these variables is not recommended to read it from keyboard, it was sugested to read it from an extern txt file from a local/network drive.
First of all, I tried to declare a file( ex: FILE *fp ), but I got an error sintax.
So, I would

I am working on RN-41-Sm bluetooth module from last 4-5 days, i interface the module with pic87k22 over MAX232 ic.
i use MODBUS protocol over USART, when i communicate with serial bus with standard MODBUS software everything working fine.
My problem is when i interface the RN-41-SM module over there i didn't get any single character even

I am using pic18f4520 MCU
I am try to implement interrupt on PORTB RB4:RB7
interrupt is works ok but RBIF is still 1 even RBIF=0
as per information on datasheet..
"The input pins (of RB<7:4>) are compared with the old value latched on the last
read of PORTB"
i did experiment on some condition to input like:
1) made high to low state and ma

What is typical condensators value for 40MHz quartz?
Step 1: I test first with 24MHz quartz with 13.5pF (two 27pF in serial connection) everything working fine.
Step 2: Then I just change quartz (put 40MHz instead of 24MHz) and PIC working about 2 times slower?!?
I suppose that I need to put smaller condensators, but I'm no

Can someone please suggest me a suitable opto-isolator for SPI communication. It should be cheap and thru-hole. This is to isolate a pic18f and a ade7758 ic. I am hoping to use a 4MHz crystal for the pic.
Thanks in advance
So is that means that your communicated signal through this opto coupler is a 4MHZ s
