it solved. the problem was about the software which i check the serial interface. my code was true. i use Hercules instead and saw everything was ok :)
hi
i trying to receive data with usart on stm32f4_discovery board.
my code do send data with my configuration,but it does't receive anything as what realterm said:(
.i check the RXNE flag also ... but it does not set either .
does any body khnow how to handle this ?
i try so many examples on...
yeah
i fixed that ...
now i just get this warning ... and try it on my own but keep getting this error ...
would you help me ....
PIOB,
PIO_Pin_1, 0);

thanks
hi...
let me clear this up:
when we do programming, we write them either in assembly or c language.at the first stage the Labels of one file is unrecognized for the other files. and when we compile it, consider the case that a function is in one file, and the defenition for it is in the another...
Hi...
im begginer with stm32f4 programming.
as a project i write a program to run keypad ... now i wanna show it on the 2*16 lcd ,every time the buttom pressed.
and i find the library,.h,.c files. but dont khow how to use it ... i add it to the project directory, and when i rebuild it i get this...
Hi
does anybody have the stm32f4xx /discovery board library for proteus?
i do programming in Keil uv5 and i want to simulate my codes in proteus, so i wonder if anybody have the library for it ....
thank
yes, actually i wanna attach the exact model, but there i cant, so i make this thread.
my problem still is what is the difference between these inputs? since i think with all of these inputs the output will get saturated! and the answer will be the same.
and my other problem is how to measure...
i think things going to be very complicated here, so here is the exact question AND i will thank anyone who could help me out with this!
consider this LM741 in open loop with the specifications attached:(LTspice)
measure the rise and fall time of the output voltage with pulses with given...
yeah, i know this, and i think our instructor want to teach us that if we use the op-amp in open-loop then we have a comparator, but this is not a good idea, and this will be proved via simulating the circuit with a pulse and see that the output in lower input pulses is not like a pulse and we...
THANKS,
but i meant to measure the rise-time with just the open-loop given op-amp!
so i design circuits for this op-amp to find the open-loop dc gain and open-loop frequency and the slew rate.
now i have this parameters, but still i don't know how to do this?
