    Make simple JDM programer with external power supply

    Hi, I'm trying to make a simple programmer to program PICs especially for 16f887. I found JDM programmer Like this: for 16F84, assembled it once or twice with 16F54 with PICPgm It gave message successfully programed or verified and then "verification failed" error started to appear. I also...

    Can We new MCU (PIC16F54) in mikroc pro for pic

    Hi, I've need to write a program for PIC 16f54 but is not listed in devices list in Mikroc pro for pic. I want to know can I add MCUin list Or write program for another compatible MCU and then run in PiC16F54 will it work?? Thanks.

    Excessive CPU load proteus

    Thanks, I change priority of process PDS*32 and simulated without error but when simulated with other components again error I also checked affinity for this process to use all processors but same situation. I also changed MCU clock frequency to 1 MHz I want to know if there is any other...

    Charge Carrier in Semiconductor

    Charge carriers are of 2 types, 1. Electrons i.e. physical particles 2. Holes i.e when an electron leaves an atom that atom gets a 1electron volt +positive charge (vacancy of on electron) and this called hole you can say it is a theoretical practical as it do not move physically but if one gets...

    Excessive CPU load proteus

    Hi, Proteus gives error message but CPU is working at less then 50%. I removed all other components and jus MCU and an oscilloscope is present for simulation but same problem. code is simple and no compiler error. while(1){ delay_ms(10); if(amp!= amp_l){ if(amp<amp_l){...

    [SOLVED] current upto 2A and voltage is 12v

    12v 4AH is the maximum current your battery can deliver in one hour, and your circuit can draw only 2 amp maximum current so it does not mean battery will damage your circuit as it will not draw current more then 2 amp until volts are increased or the circuit has some kind of shortage so for...

    [SOLVED] Pwm out put through rc0 & rc1

    actualy Ii'm trying to work with ccp module of 16F887 and not well aware of it I seen a ups control card havin g the same MCu but it confused me as only one ccp module pin is used. there are 2 same similar portions of circuit as shown in fig both drive a module conected to a center taped...

    [SOLVED] Pwm out put through rc0 & rc1

    I'm confused after seeing a circuit with pwm signal for a 50Hz inverter which used RC0 & RC1 of P16F887. RC1 is CCP2 out put its ok but how RC0 works same as RC1?

    problem on calculating the ouput power of an inverter power system

    you can calculat by formula P = V*I OR P = I^2*R. Or explain your problem a bit more.

    [SOLVED] DSL sharing at long distance

    Hello every body, I want to use cat5 for sharing dsl connection at a distance of more then 400 feet and don't want to use repeater in mid of cable. I have idea that if I use each pair of cat5 as an separate line it will reduce resistance to half, will it be usefull or will make problem due to...
