    [SOLVED] 3.3 volts on PIC microcontroller.

    Thank you guys very much. U are right about the 87J60 it uses 3.3 but apparently the board that I am using had a 3.3 to 5 converter. This is why I was seeing the 5 voltage. Thank you again for pointing that out.

    [SOLVED] 3.3 volts on PIC microcontroller.

    Hi I have a 5 volt 2 Mhz signal that is being generated by PIC18F87J60 and PIC16F877A, I am trying to feed that signal to a take an input of 3.3 volts. The problem is the 5 to 3.3 volt converter will take 7 days to arrive so I am trying to come up with a quick solution. I went through the data...

    SPI Working Code! two PIC - MikroC

    Hi Thank you for your post but I don't understand the part where u say " I changed the inbuilt "Spi_read()" command and used direct Registry reading as in the data sheet. Then it worked" Can you clarify that more. Regards.

    ESD on CC2500, advice needed

    Hi I am about to start using the CC2500 chip and while reading the manual I read "ESD precaution should be taken". Should I take this warning seriously or I can just ignore it (because it is written on most of the electronic components). Did any one had troubles with ESD when working with the...

    low cost wireless transceivers with tunable frequency and power

    Hi mailus, I understand that the nRFL01 has some predetermined 125 channels so I can choose a channel not a real specific frequency, is that so? Keith, thank you for your note, a chip or module will do it for me. Thx for pointing that out.

    low cost wireless transceivers with tunable frequency and power

    Hi I am looking for a low-cost wireless module that is working on the 2.4 Ghz or 5 Ghz (or any other unlicensed frequency). I will be using it to run in-lab experiments. My preference is something with variable output power and tunable frequency. Most importantly I want the module to function as...

    wireless transceivers

    Well you can use cheap modules like TWS-433 and the RWS-433 which can be easily interfaced to a micro-controller then you can do your job within the micro-controller, i.e. to make the micro-controllers communicate their status to each other. I think you need to make your own network algorithm to...

    How integrate ∫ y^(x) dy

    Well thank you guys very much. the LHS is just f(x)= ∫ y^(x) dy So I think I can integrate over y and consider x as a constant as you said. Thank you again.

    How integrate ∫ y^(x) dy

    Thank you very much So can't I just consider the x to be just like any other constant since I am integrating in terms of Y because the final result of the integration shows that X behaves just like any other constant, is this right or I am missing something here? Regards. Anderson

    How integrate ∫ y^(x) dy

    Hi I was wondering how would I integrate Y to the power x over dy ∫ y^(x) dy knowing that both x and y are variables, let us. Can I treat X as a constant in this integration or what? Regards. Anderson.

    Electronic components supplier in Orlando, Florida

    Can you recommend me Electronic components supplier in Orlando, Florida Hi I just moved to Orlando, Florida and I am kind of new to the area I live in the UCF area (32826) can any one recommend a near by store that sells electronic components (the usual stuff) TTL's, resistors, capacitors, H.W...

    How these transistor circuits work?

    Although I did not practice electronics since a while, but I think this circuit is an audio amplifier and one channel will amplify the positive part of the speech signal while the other will amplify the negative part of the speech signal.

    How much is the input impedance of the 74 TTL family

    Hi how much is the input impedance of the TTL logic devices, for example if you have a transistor feeds a signal to a 7404 (for example) how you will deal with the input impedance of the 7404 when you make your calculations? we hear that the TTL family has high input impedance in order not to...
