Hello...
I did a circuit for sending serial data to the computer, so i used max232 ic.
I used 1uf non polarized capacitor for the max232, but i figured out that in the datasheet they are polarized capacitors.
Do i have to change the capacitors or they will work fine?.. anyone has explanation on...
:D thank you waseem the problem was in this part, because i used COM1 in both matlab and proteus so because of this matlab shows me that the port is used by another softawre, when i changed the port in proteus to COM2 the data transferred successfully:D
Yes waseem the devices are shown in the device manager when i add the virtual ports, proteus also has a serial port block so you can interface between different programs.
I'll try it in a computer which has a physical serial port, to see if things will change.
Am trying to turn a led on and off from the computer, this is done using a serial port interface between the computer and the microcontroller which will take the decision to what to do according to the data transmitted from the serial port.
I trid your code but nothing changed, matlab gives this error
??? Error using ==> serial.fopen at 71
Cannot connect to the COM1 port. Possible reasons are another
application is connected to the port or the port does not exist.
I don't have a physical serial port in my laptop, but i...
Hello
I am trying to make an interface between pc and pic16f877A, which allows me to switch a led on and off using a push button.
i made the gui in matlab and programed the bushbutton, and then i wrote the microcontroller program, but while i was simulating it in proteus nothing happens, i...
It's very intersting, thank you very much flex
but i have a question concerning the charger.
how did you convert the ac voltage to dc voltage? is there any external circuit with transfomer which makes this conversion?

Hello...
i have a small project in the university concerning sine wave dc/ac inverter.
i want to run a small induction motor, so the maximum power of the inverter is 1200w.
i did the control part and i generate a sine pwm signal from pic18f2331 microcontroller, but my problem with the IGBT and...
