• Fused crystal oscillator

  Madam/sir,What do we mean by fuse bits and fused crystal oscillator? Don't mind but, because of Electrical Engineering, had Eletronics in syllabus but don't have that much background idea, these words are somewhat new to me. How a simple writing operation of fuse bits will cause a huge damage to the Microcontroller, we are simply configuring them to some other value than the defined value.Also you said in precaution section that, we should remove all the external connections with mainboard except USBASP programmer while flashing into the memory of Microcontroller from the PC. But, doesn't the given supply of SMPS to the mainboard may contribute to a damage to the microcontroller.

• Problem with windows command prompt

  I am unable to access the ldmicro.hex file saved in the desktop. I reached upto C:\Users\Shubhankar\OneDrive\Desktop>. After that what to do I am not getting. What should I type in the command prompt for accessing ldmicro.hex in the desktop? Madam, please make the students ready with the windows operating system also. Please share me the screenshot what you will do for the same operation which you did to access the file file in Ubuntu, to be done in windows. I am very much confused in that also since we are electrical engineer students, we know some programming languages like C,C++,Java which were in our domain to study, but we are somewhat lame students in using command prompt. Please guide us using such operations on ground level.Also do we need to have the hardware? We don't have them with us how to use them/access/purchase them? I don't think they are available freely in the market if yes then how to purchase them, are they less expensive? Also can't we study and perform the operations without hardware by seeing the videos or using simulations or using virtual labs offered by some of the prestigious institutes such as IITs & IISc, in case we don't have the hardware. As you burned or say have transferred the program to the Mainboard  of OpenPLC, how can we perform such operation or say experience it in actual process without hardware if we can't afford them say by using virtual labs or some other source/way? For this purpose we  need your help. We the students want every aspect of the learning process to get unturned so that the person reading our resume can't question over our learning process and ask us what's the benefit of learning from such premium institute without having a proper knowledge of PLC.
