    [SOLVED] Error in Programming PIC18F4550 with the K150 PIC programmer

    Hey :-D The problem is resolved by upgrading the hex file. Thank you very much guys. I am now capable to Program both of that controllers by upgrading the hex file of 16F628A controller on the board. Thanks for guiding me to the right way. I can now proceed further in PIC18F devices. Jaydeep

    [SOLVED] Error in Programming PIC18F4550 with the K150 PIC programmer

    Thanks Brian and BigDog. Actually I am running the latest version of microbrn software in my PC because I bought this programmer in 2011 and the last update of its software made at 2007 so I just need to re-flash 16F628 controller in programmer with latest hex file and try again. But as of...

    [SOLVED] Error in Programming PIC18F4550 with the K150 PIC programmer

    Hello everyone, I got K150 PIC programmer. The programmer successfully programs PIC16F877A microcontroller. But when comes to PIC18F4520 and PIC18F4550 controller, it gives error in verifying the flash at 0x0000 location. The programmer is supposed to support these two controllers and I...

    Need help in my project of "Clock with Selectable Alarm" using PIC16F877A.

    Re: Need help in my project of "Clock with Selectable Alarm" using PIC16F877A. I don't think that there is the stack limitation problem. Because I can run the same-like code in MPLAB Hi-Tech C without getting this type of error. So currently I have to translate the code for Hi-Tech compiler...

    Need help in my project of "Clock with Selectable Alarm" using PIC16F877A.

    Hi all, I use MikroC, can also use Hi-tech C. In the code for my project, I cannot call any function from the interrupt routine. I want particular function to run in my code when i press the switch. I do not want to update any value in interrupt and scan it in idle condition and run according...

    Good books of ARM Architecture for beginners

    I apologize for that. Actually I have seen that most of the microcontroller books are available from this author. 8051, PIC, AVR, x86, all major controllers are covered by this author and that is of great way. And I believe that ARM is also covered. But the author's website doesn't list this...

    [SOLVED] DS1307 RTC problem on PCB

    Hi palreddyanurag, You are right, I was in a frustrated state because I am trying to interface and run this IC for a past 4 days. I had in my mind that, I run the circuit successfully in Proteus then I would not face any problem in breadboard also.(except the 'ACK' signal that Proteus...

    Buckboost LED driver with TL431 or opamp in feedback loop?

    hi, treez here, I must say that the LT1006 is an op-amp and TL431 is a 2.5V voltage Regulator. You mean LT1009, I guess. If you, then For TL431, it is very effective voltage regulator. As my opinion TL431 can be used in this circuit. I suggest you to first practically run this circuit with...

    What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

    Re: What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor. Hi, awaw. First of all- I am sorry for a long time. Hmm. I am using v16. Well, you are right that the net-list is the better way to make PCB. We have to just make proper connections between the pins keeping in...
