Please help sourcing this USB security dongle which i am using in a software. As my present supplier is no more with us and thus I am looking for exact dongle from China or India. Will require at least 200 -500 Nos but need the exact product. For general info, this dongle is based on Cypress...
Oh..i just saw the first post where he didn't mention about the simulation. Proteus is not 100% accurate and cannot trust i always. Only results on real hardware are practical and accurate. Try assembling the circuit and re-check.
You can opt to get a service from the company where they may replace the main board or tel that this model is old and no more supported in their service. Thus buy a new one. OR you can choose to get third party service where some other technician may have the same board which can be used as a...
As i understand you are from India and here we have a lot sources with spurious and fake Chinese components. The DS1307 runs with an external crystal of 32.768khz which is problem in this case. The crystal will not be accurate compared to its marking. Next the temperature too will act a lot to...
Provided you have a working blink program .hex file and program it with internal crystal option selected with proper fuse settings, it should work fine. Absolutely no rocket science in it.
i guess no need to reinvent the wheel. Ample schematics are available for the same. But 12v @ 12 amps will probably not powerful enough to heat a liter water in short time. I am using the same for experimental purposes. Contains just two coils, two mosfets, two 0.33mfd caps and few other passive...
Yes..Thanks a lot. It started responding. The "Check MCU" reads all parameters and hardware settings. My next requirement is about how to read the hex files inside? Because i couldnt find any option in the STC-ISP tool 6.8v i am using. Or is it so that the chip is only programmable but not readable?
Yes..i have also tried the below mentioned:
TX pin from CP2102 converter connected to the cathode of 1N4148 diode and anode of the same connected to the RX pin of the Microcontroller
RX pin from CP2102 converter connected to a 330E resistor and other end of the same connected to the TX pin of...
I am new to the STC micro and trying to read a STC15W404 microcontroller Can anyone guide me the correct software and way to do this? As per information found on the internet, it is communicating with TX-RX pins but i am not sure weather it will work with a USB uART module. I have downloaded the...
I would prefer ProgISP software with USBasp programmer. Khazma acts as a malicious file for me. You may have a try with ProgISP. Cross check your connections from Programmer to the Device. Confirm the device is powered with USB or External. See that you are using "Slow clock" mode with the...
Re: Measuring 3 Phase voltage through PIC micro controller
Casually asking why re-invent the wheel? You'll get a lot of panel meters which will display 3 phase voltages and those which are not using any transformers except those for the power supply SMPS section.
Experimenting is always fun and one can acquire a lot knowledge. Buying a finished product is always a last resort for a true hobbyist or experimenter.
SM, SC series are fakes makes from china available for dirt cheap prices which never work or have problems later. Try getting the Original TSOP from reputed dealers. Finding the right dealer is a bit troublesome but the circuit will work for sure.
Thatz the fake one available abundantly in Indian market which will never work as expected. Try to get TSOP1738 or TSOP1736 or TSOP1228 or HC0038 which will work fine. Try the exact component on online sites like
