    how using 16f877a+Enc28j60+MikroC

    again, is it impossible to simulate PIC Embedded enc28j60 with proteus ?!! Hi the most repeated question. how to simulate PIC Enc28j60 in proteus this project http://www.libstock.com/projects/view/487/pic-16f877a-8mhz-enc28j60-mini-web-server that i made but after i design it in proteus...

    help in string manipulation (mikroc)

    hello every one i would ask you in issue i faced it when i make a simple prog.... if i have a string series such as char st[10]="683664791" here i want to get every character and convert it to integer to make on it some math operations... the problem is : how i can get ceratin character in...

    how i configure my router with ethernet controller?!

    hello every one now days , i made a project "Ethernet Controller" that uses 16f877 and ENC28J60 and it works successfully with direct connection with CrossOvr cable to my labtop but i want to connect my project with enternet through router can any one give me the global settings for router...

    help in ethernet controller code

    hello every one i would ask you in an example embedded in MikroC that illustrates how to use PIC to control through ETHERNET i executed the example and it works successfully , here it's /* * Project Name: enc28j60Demo (Ethernet Library demo for ENC28J60 mcu) * Target Platform...

    question about CANbus

    hello every one i would ask you about something called CANbus to network Microcontrollers i read about this type of networks and i found that it is high performance network .. and i want to use it simply to connect two PICs. ,, in Mikroc PIC , i found a library specialized for CANbus .. but...

    ques in uln2003 with NPN transistor

    thanks for your explanation guys :) i searched for uln2003 and i found that it's only can out sink voltage ,,, (common) while source always exists . that's mean that i must use pnp ,, but i think of replace uln with npn or pnp transistor only but my matrix (or 7seg) needs about 3 amp and 30...

    ques in uln2003 with NPN transistor

    hello every one ,,, i would ask you a question in uln2003 i connected a uln2003 to PIC to trigger it from it but the problem that i want to use uln to drive matrix that has high amp so i want to connect NPN transistor after uln but as i saw that uln only out an LOW(COM) state how i can make...

    question in dealing with LPT IO pins

    thanks a lot mr.HTA for ur link here i draw a schematic how to change the pin1 of lpt as PIC rb0 ,, when i trigger bc337 , the state of pin1 is "1" , else state is "0" So is this schematic right?? ,, i don't test it in fact ,but i would know if it is right ,, what's is your opinion ?

    question in dealing with LPT IO pins

    hello every one i have a question about reading lpt data that PIC control them , & i made a software to read from lpt ,,, but the issue in connecting PIC with lpt ! i mean >>> can i connect LPT pins directly to PIC pins (such as PORTA) ?!! or are there any equipments that i must connect...

    help in my IR cut beam !

    hello every one i have a simple project that just detects an IR cut beam i use 16f877 - MikroC , with receiver and transmitter of IR here i use PWM in pic to generate frequency to the transmitter , that's code PWM1_Init(38000); PWM1_Set_Duty(255); PWM1_Start(); that's mean ,,, i want to...

    how i can make lux meter in mikroC

    hello every one now days , i make a project that measure lighting with a normal LDR sensor using 16f877 and mikroc, (LDR connected to AN0) and the adc in PIC reads the voltage from LDR that connected with 10K to power, that's OK. but i want to make a lighting measurement that measure the...

    question about internal interrupt-MikroC !!!

    thanks mr.paulfjujo i don't use any protocol , sure i deal with UART library ,,, and this is my code and i will explain my problem in it by comments: char string0; if (receiver_active==1) { // here i just connect rf receiver(vcc) to pic pin for enable it while rf transmitter works...
