  1. Closed: Re: Altium - how to map pins to multiple pads?

    Instead of assigning the correspondence on the footprint/component library, you can just connect them by wire in the schematic side, which seems a more realistic approach, once you are connecting...
  2. Closed: Re: NodeMCU sinking current through DIO while power is off

    The above arrangement with diodes could do that with no need to add any transistor as simulated bellow, however not acting on GND, but rather on supply bus itself, so once any button is pressed,...

    Closed: Re: Embedded Linux Applications

    Not all ARM cores, but the ones which meets some requirements in their instructions set; actually most of them.
  4. Closed: Re: How to import all the rules in Altium at once

    By clicking CTRL+A will select all rules.
  5. Closed: Re: ir pair not wark behind black acralic

    By the succinct description "the IR doesn't work", do you mean that it detects when it should not, or simply does not detect at all? As a rule, since you are using the same optical barrier for both,...
  6. Closed: Re: Prevent short-circuit design rule in Altium when drilled hole goes through a pad

    You just changed the PCB editor's color preferences, you didn't actually set the rules this way, instead just tried to hide the warnings from your sight; as said before, still on the schematic side...
  7. Closed: Re: Prevent short-circuit design rule in Altium when drilled hole goes through a pad

    For some specific cases you can add on schematics side, PCB directives in order to instruct online DRC from Layout side to consider differentiated rules.

    Closed: Re: Rotary encoder physical dimensions

    Not why 5, but rather why 6,35mm; that´s because this 0,35mm clearance would allow you to plug the 6mm axis with some easiness if compared to the 6mm-6mm option; not too tight, not too loose.

    Closed: Re: Rotary encoder physical dimensions

    Once the encoder axis diameter is 6mm, I would choose the coupler with internal diameter specified with 5-6,35mm. The tighter, the lower the chance of future wear problems due to being anchored...

    Closed: Re: How to use TL431 Model in LTSPICE

    If you mean by those few words "how can I get models and examples of TL431 on LTspice" the answer is on Google as many others, anyway:...
  11. [SOLVED]Closed: Re: how ro export my proteus project from one pc another?

    If you are referring to attach the firmware within the project file, go to the "Source code" tab, "Build" menu, "Project Settings" option, and click on the "Embeed files" checkbox.
  12. Closed: Re: Does PIC16F18856 work if centre pad is left floating?

    From my previous experience with another Microchip's relative of the PIC16F's family, even forgetting to route one of the side pins of a DIP package, this was enough for the microcontroller to not...
  13. Closed: Re: Unable to read data from RTC DS1307 using Atmega8 and mikroc.

    Thanks for the warning, I will correct the code suggested above.
  14. Closed: Re: ESP8266EX based wifi module does not respond on any AT commands ( E103-W01-IPX)

    No, this library is used to make ESP8266 module connect to Wifi network from a board which has a bootloader already programmed there (Arduino, on this case). First you need to setup your Arduino IDE...
  15. Closed: Re: Unable to read data from RTC DS1307 using Atmega8 and mikroc.

    Just to let you know: Soft_I2C_Init() has a different purpose, it is intended to enable the I2C bus from microcontroller`s (master) side, whereas RTC_init() would enable the DS1307 (slave) throught...
  16. Closed: Re: Identify capacitor with marking code L62 104

    Who mentioned that? Datasheet? Mark code?

    Review post #2:
  17. Closed: Re: Unable to read data from RTC DS1307 using Atmega8 and mikroc.

    In the line 125 there is this function, disabled:


    //RTC_Init();

    Which certainly should be some routine for checking and ensuring that the clock would be always running, by resetting bit 7 of...

    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...
  19. [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.
  20. 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...
  21. 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.
  24. 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...
  25. 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...
