Sir,
I want to program At89s52 mcu (C51) and as i have a laptop (no rs232) so i want to use CP2102, (USB to UART bridge) and i think of using the RX and TX pins of the mcu but i am unable to find any software to burn the code successfully , please help me , i really need this !! :-( :-(
NOTE...
but there is no Max232 on the arduino board
and i still didn't got about the baud rate ...
do i need to change it ? or not ?
please explain :cry::cry::cry:
OK , do i need to use MAX232 with CP2102 ? as its an usb to s232 converter the output should be first given to MAX232 ? right ?????
.
.
then
the data sheet of CP2102 have these lines
"The UART is programmable to support a variety of data formats and baud rates. If the Virtual COM Port drivers...
Thank you , but if same condition appears before me .... how should i then decide the rating of my capacitor to reduce the noise ?
i have usually seen using 104 but whats the logic behind ?
actually i have a laptop that don't have rs232 port.
can i program my at89s52 using CP2102.
I haven't gone much through its data sheet but it have an EEprom in it.
and i have one of such ic being used to program atmega8 (actually its mounted on the arduino board ) can i use the same ic to...
yes i have read some where about comparators but i dont really know what the are......
please explain ! :)

OK OK maybe i got it ,
The sensor board on it have a potentiometer so the when we change the pot meter's resistance the reference level to the op-amp must be changing...
I bought arduino board using atmega8 micro controller and i got IR sensing boards with it. the board are mounted with an op-amp LM358. I am not getting the purpose of that op-amp. please explain !
Sir,
i wished to use my cellphone as dtmf transmitter and receiver so as to make it communicate through air and for dtmf , i wish to use MT8870 dtmf decoder and the datasheet have a text saying "Following the filter section is a decoder employing digital counting techniques to determine the...
Hi !!
I am working on a robot and i need to control it through wireless communication, at first i thought to use a R.F. module for it but the area where i m going to finally present my work will have many more bots and many more R.F. modules which may cause noise problem and control failure ...
