    Closed: Re: NodeMCU ESP-32S pitch

    If you have these boards in hands, why not you measure them? By the way, at least with the ESP32 relative, the ESP8266, there are a number of NodeMCU's variants from many manufacturers, therefore in...
  2. [SOLVED]Closed: Re: LM741 Amplifier not working with IR2110 IC [PROTUES]

    With the above value at VDD of IR2110, the HIN pin allows input varying from approximately 0v to 12v, but the 741 has differential supplies ranging from -10v to +10v.
  3. Closed: Re: how to design a thermostat without Microcontroller?

    So far you do not seem to have done any more detailed analysis of the physical plant, as was proposed on the first page of this thread where the possibility of a less abrupt control (eg PID) was...
  4. Closed: Re: Unable to read data from RTC DS1307 using Atmega8 and mikroc.

    I can't see in your code the 7th bit of Address 00h (CH) being set anywhere, which should be done at least once after DS1307 got powered. It is responsible for effectively starting the RTC...

    Closed: Re: hex code to Assembly

    Yes, this is called disassembling; there are tools for many compilers, make a search by yourself on the web.

    Closed: Re: AD9288 is not working in Proteus

    There is no code on this attachment, of if there is somehow embeeded in the project file, not everybody has this program.
  7. Re: Help unlock microcontroler atmega644pa-mu

    Fuse bits are designed to protect microcontroller contents from unauthorized copy, therefore it is just acting as expected. However, if you want to not waste this chip by uploading another code...
  8. Closed: Re: Setting Counters and ISR Timer Interrupt in Arduino

    Since Arduino is a platform that must be compatible with several microcontroller architectures, the standard features are in fact tight facing to all ressources that each specific core have. If the...

    Re: Transformer and alternator

    This thread became unfruitful and moods have been exalted again although ads-ee requests for avoiding that, so it will be closed.

    Fact: The mentioned video does not represent an actual simulation,...

    [SOLVED]Closed: Re: Sleep mode - dspic33ch128mp508

    Didn't you find anything on instructions set of the compiler datasheet like that ?


    sleep();

    With a quick search on the Web I could easlily find the assembly instruction that do the same:

  11. [SOLVED]Closed: Re: ADC reading , Timer interrupt - dspic33ch128mp508

    Don't seem it is likely missing something like that at the init routine?


    INTCON2.GIE = 1 // enable global interrupt

    Seriously speaking, take a look at other extensively available examples on...
  12. [SOLVED]Closed: Re: ADC reading , Timer interrupt - dspic33ch128mp508

    It seems like you are missing the command for starting the A/D conversion, either at the main() and at the interrupt() vectors:


    ADCON3Lbits.CNVRTCH = 1;

    Moreover, you are not enabling...
  13. Closed: Re: PIC microcontroller debugging- dspic33ch128mp508

    You did not specify what programmer you are using, and what pins are aavailable to programming connector, anyway if I were you I would investigate this line:


    #pragma config JTAGEN = OFF // JTAG...
  14. Closed: Re: [Microcontroller] Voltage Reading without ADC

    From what was posed so far, indeed not clearly, it is assumed that OP wants to simply detect the battery low-level (supposedly lead-acid, given the above values), for which he certainly is not aware...
  15. Closed: Re: Tuning of varicap diode in a magnetic loop antenna based on modulating signal

    Should we assume that your doubt concerns an unconventional case of a demodulation without use of intermediate frequency in the receiver side? This feature is designed to allow the transmission of...
  16. Closed: Re: LoRa nodes and simultaneously communication with LoRa Gateway

    Collisions are not intrinsically handled with LoRa protocol, which means that proper packet management have to be externaly done by end application at each node in order to ensure that all command...
  17. Closed: Re: Is it possible to assign a value to a signal in a systemverilog assertion?

    This is a regular statement on this language.
  18. Closed: Re: Deadband and Hysteresis values from graphs

    The above 3 graphics are on different scales, so in order to make things easiest to understand I put everything on the same grid.

    For the first case there is neither deadzone nor hysteresis, there...
  19. Closed: Re: Does it exist an AC to AC converter in small package for converting 220v to 110v?

    No, this was not the point, but rather to advice OP about the correct value of the absolute maximum firing angle to be adopted in the design of the control circuit, just that.

    BTW, some fans have...
  20. Closed: Re: Does it exist an AC to AC converter in small package for converting 220v to 110v?

    The maximum peak voltage dimmed from 220vac equivalent to the peak of 110vac should be considered regardless of the rms voltage delivered to the fan.

    The half voltage is obtained with a firing...
  21. Closed: Re: how to design a thermostat without Microcontroller?

    @Dr_Mohammad, your above (deleted) post contained exactly the same schematic diagram with the same values posted more than a dozen posts back, despite all the calls to present the circuit diagram or...
  22. Closed: Re: copper pour in top layer with vcc net

    Should we assume that you ran a DRC check on the final completion of the board design so that all the routed connections match the electrical diagram? If the schematic is correct, there is no reason...
  23. Closed: Re: Coin Slot acceptor Timer using PIC16f84a

    You are expecting that end user will insert only one coin and await for the end of the process, and only after this moment to add another one. Coding blocking inline as this is not the recommended...
  24. Closed: Re: dsPIC30F2010 - 30 I/SP restarts at interval of 20seconds for no known reason

    Are you sure that the compiler supports this syntax?


    _FWDT(WDT_OFF);

    According to Microchip's datasheet (154359), the correct one for 16-bits microcontrollers seems like being rather that:

    Portable thermal camera readers are often used to determine if there is, or what device, are hot in the board. If you get an affordable one, perhaps you could be able to - with certain degree of...
