    TCP client on GPRS Problem

    Yes my modem is connected to the network correctly because I am having AT commands to connect to client and it connected well and then i can receive the events but when I use TCP create client API inside a task inner event this problem is appearing (that is no events come although the...

    TCP client on GPRS Problem

    Thank you alot for your reply I tried what you said to me and now the Open TCP client API works well but there is a small delay reach up to 30 second to give an error that it cannot connect to server can this time be reduced ?

    push button debouncing problem

    push button problem hi all , I need a circuit to take the pulse o/p from the push button then make it accurate .there is a distortion in the pulse although I use pull up resistor=10k and a capacitor 1nf what should i do ? thank you alot

    USB connect to PIC 18F2550

    By any normal pic programmer by serial (as JDM programmer) using winpic800 or picpgm you can see the examples in c:/program files/Mikroelektronika/mikroBasic/Examples/EasyPIC5/Extra Examples/USB HID/P18F4550/USB_HID_test I advice you to begin with learning hid class as the example shows.

    Circuit for measuring the peak of sinewave in range from 0 to 5 v with high accuracy

    Re: peak detector design thank you alot Petre Petrov 1. To detect the positive peak? yes,i need to detect postive peak. 2. Frequency from approx 0 to 100 kHz? frequency is fixed 100khz but i can change it to 1khz . 3. Tested at 5000mV p-p? yes,from 0 to 5 v 4. Accuracy in amplitude better...

    Circuit for measuring the peak of sinewave in range from 0 to 5 v with high accuracy

    Re: peak detector design thank you alot for the replies. Now what i should do ? i tried more with my circuit .it works well but i didnot achieve my gool (peak detector with 5mv senstivity).my application is RC meter and i used peak detector as a small (but its very important) step .can you help me?

    Circuit for measuring the peak of sinewave in range from 0 to 5 v with high accuracy

    Re: peak detector design thank you. I put var resistor to solve the problem of voltage offset .The comparator is TLC372 .The error is changed randomly and it is about .3 v and i want senstivity 5mv

    Circuit for measuring the peak of sinewave in range from 0 to 5 v with high accuracy

    Re: peak detector design thank you alot I used opamp TL070 instead of LM358 and i decreased C1 to .5uf but it still inaccuracy.i need 5mv senstivity .can you help me?
