    Drill holes not visible in PDF of artwork on Designspark.

    While taking PDF from artwork drawn on Designspark, the drill holes on copper filled area are not visible. Holes of other areas are visible. A PDF is attached hereunder.

    Cannot get the code of Sensorless BLDC ESC

    But what about the if/else if condition inside the for loop where the variable is decremented?

    Cannot get the code of Sensorless BLDC ESC

    OK. Then the local variable j is once incremented in for loop and in the following if condition it is decremented. I get stuck here. Please elaborate a little.

    Cannot get the code of Sensorless BLDC ESC

    Hi guys, I am interested to make one Electronic Speed Controller to drive a small Sensorless BLDC motor. After thorough study of some application note, tutorial and article on the web, I got one code which is given as under. In the code, the variable 'j' is defined as global as well as local.In...

    Project not shown in MikroC

    Please see the screenshot. In the Window List, the top most file is my lost project which is shown as hidden state. I don't know whether the file could be restored from hidden state. If possible, how?

    Project not shown in MikroC

    I think my project window is hidden. When I go to Project - Open Project then my project name exists in the list. But when the project is opened,it shows nothing but the same as screen shot.

    Project not shown in MikroC

    Hi guys, While working on a project in MikroC compiler, all of a sudden the project disappeared though the name is shown on the top bar but without any work. May be I have done anything wrong. Please see the screen shot and suggest how it could be restored.

    pic16f72 pure sine wave inverter

    wissy, So far I have got from your posts, you lack the basic concept of SPWM inverter. So it will be a cumbersome job for you as well as for the well-wishers trying to help you to make a success of the project. You better to study related topic and grasp the idea. An excellent article posted by...

    pic16f72 pure sine wave inverter

    Really the above project of Sine Wave Inverter has got viral. I have seen some guys posted the project on their blog claiming it designed by themselves. Being an electronics hobbyist, I bought the technology from a person who, after getting payment made a long dilly dally and finally mailed the...

    Led working but relay not working with BC547

    The datasheet of BC547 shows a DC current gain in the order of 110 - 800. So biasing base with 1K resistor should be sufficient to drive the relay. What is the resistance of the relay coil. You might have replaced the relay by LED with current limiting resistor. What is the value of the resistor.

    Problem in firing the TRIAC

    See, this zero crossing pulse appears at every 10 millisecond. So, when you attend this zero crossing pulse within ISR or polling, some amount delay should be there before attending the next zero crossing pulse so that firing of TRIAC at wrong position could be avoided. Have you made any logic...

    Analogue input for ADC higher than Vref

    Hi, External Vref of 16F72 MCU is clamped at 2.5V. What will happen to ADRES register returning equivalent digitized value of analogue input of 4.0V? Would it return 0xFF or otherwise? In practical hardware of a volt meter circuit I have noticed that when input is increased gradually from 0...

    [PIC] Relay on/off only two times

    On powering up, does your relay behave like (ON - OFF - ON) ? I guess, after that, the relay does not get OFF. If this is the case, then look at your code. When the temperature goes above 100 the condition "if(k>100) " meets and the counter i.e. flag increment takes place. This increment goes on...

    [SOLVED] [PIC] Need help for PIC12F675 Based 12V battery charger

    Yes, it will be like that. I have given you the idea how to introduce software hysteresis in your code. If you like to switch on the charging relay at a level of 12V of the battery, then put the corresponding value in "if(adc_voltage <= 2.000)". You should know that when the battery is...
