What sort of bluetooth device is it?
I dont suppose it registers as a COM port so I dont think that the MSComm control can be used. Does it use an specific DLLs for wrapper functions?
Re: Regarding GSM modem
Do u have the datasheet of the module?
U need the datasheet to find out about the pin connections and signalling b/w the microcontroller and the module
After that u can simply use AT commands to make calls or read sms etc.
vb to send at commands
1) Please add a ListBox to your form. I used it simply so that I could list all the messages in the phone.
Also make Text1 multline (in the properties) and add scrollbars too.
2)When I send AT+CMGL, the result is not OK. Infact, the phone sends a list of all the messages...
You can use MSComm to read integer values from the serial port. You dont need to worry abt the binary conversion.
Then you can use a picturebox to show the graph but try to keep the dimensions low. VB pictureboxes are memory hogs and can be really slow.
Re: Matlab Help
Why dont you use the Matlab help?
It pretty simple I think. Generate the chirp signal then take its FFT and then plot it
t = 0:0.001:2; % 2 secs @ 1kHz sample rate
y = chirp(t,0,1,150);
f=fft(y);
plot(f)

Okay potetojb, I've checked your program and there are a few things to modify although its a very well written program.
When you set the InputLen to Zero, that means that the MSComm control will read the whole line at once so you dont need to worry about buffer sizes.
You...

If the device is detected as a modem, you need to know which COM port it is attached to.
Go to Device Propeties and check the properties of the detected modem and check which port it connects to.
Then in VB add the MS Comm control, and set the properties.
I suppose you should...
Re: Verilog coding question
I suppose the best way would be to implement a complex number multiplier yourself.
You would have to store the real and imaginary parts in separate variables and use both of them when you need to manipulate them.
Re: who has some example about imaging processing programme
I'm not sure what you mean by image processing program in Verilog.
However I did make a JPEG Encoder for Image Compression in Verilog.
Would that help?
