    What kind of chip is used in my circuit board?

    Instead of replacing chip, better replace the board itself, ex-https://hacktronics.co.in/music-tone-generator/px088a-children-music-chip-9300-line-long-ringing-music-ic

    CT Connector Self Short

    I understand, but I need to know type of the connector to search and espeacially whether this type connector exists. Specifications as : Right Angle, 10A, 230V (size doesn't matter but should not be greater than 5.08 pitch)

    CT Connector Self Short

    Hi All, Help me in choosing CT Connector that auto shorts on removal. The secondary terminal of CT should always be short, since we are connecting two meters in one line. very often if we remove CT in one meter then it gets open. Hence needed the connector plug that auto shorts on removal...

    Variable PWM on multiple GPIO

    Hi all, I want to generate variable PWM (to blink LED fade in and fade out) on multiple GPIO pins. With this I could able to get, but the signal generated is sequential. Like A -> B -> C -> D. I want all these should go in parallel. I know that if I use PWM then I can get it. But my...

    Physical and Virtual Address during debugging

    You didn't understood my question, I asked for why during debugging watch could able to read the memory value but controller not able to do?

    read back the complete program of main

    simply capturing instructions means nothing. for your case if you want to jump from one memory to other and execute from there you can uses something like this void (*fptr)(void); fptr = (void (*)(void))YOUR_VIRTUAL_ADDRESS; fptr(); If you want to capture main(), then you can pointer to...

    Physical and Virtual Address during debugging

    Hi, I came across a problem today here is my code #define NVMEM_ADDRS_PHY 0x1D07000 //Physical address #define NVMEM_ADDRS_VIR 0xBD07000 //Virtual address DWORD Flashval; DWORD *Flashptr; //Working to read the value Flashptr= (DWORD *) NVMEM_ADDRS_VIR; Flashval = (DWORD)...

    [SOLVED] Jumping to an erased location

    I think it should be address error trap, since the handler for this exception is reset. They are using this to jump from application to bootloader. So for micro PIC we can't use the same technique to jump. Thank you guys

    [SOLVED] Jumping to an erased location

    Hi, I came across this following code, and my understanding from it as, the particular memory is erased and the same address is pointed by a function. Using this function pointer the address is invoked. my questions is what will the behavior is accessing or jumping to an erased memory, most...

    Status of AC appliances

    with simple resitor I could read the voltage. But how can I connect to my Controller, I don't think there is Isolator works on input AC and Output DC can you elaborate?

    Re: Pic16f690 interfacing wih two 7 segment using 7447 delay using timer 0 Are you want to use a counter...??? then what is the use of RB7 in program and circuit. Also your code seems to be good, but what about the configuration bits you used...??? In proteus have you set the configuration bits...
