Serial COM Tutorial Part 4 (Visual Studio C#)

This tutorial shows how one can use their PC virtual COM ports for easy serial communication.

download the example code (C# serial instance messaging):

BTW, check out my other video tutorials for C++ serial COM

you can download the c++ example:

Have fun!

thank you for the serial-port tutorial...I was badly looking for one. you should make more tutorials for serial communication like b/w microcontroller and visual C#.

Hi did I over see a Video of you on how to make the combobox with all the available com ports and how to use them in c#? Would be awesome to See this in a video of yours.

[bowensong]

I love this one, I can figure the rest out by my self, working in c++ but c# helps

[carlosbarberis]

GREAT If I could only figure out the other half of it; receiving from the serial port that would be great, any chance you will do a tutorial on that part?

How come you chose COM18 in the end? I can't get the program and putty to communicate.

Hi Kelvin,

 I am following your videos to connect PC to RS485 interface by using USB to RS485 cable provided by FTDI(which i use in VCP mode). PC program is in C# VS2010

I am facing a issue.

I am just trying ton send a character on rs485 link from C# program.

When i check at PCs actual COM port output trammit line and see data on scope no problem i.e i see 10 bits. But when i use FTDI  vertual COM port i see one additional  zero bit getting added to the data i.e i see 11 bits, for the identical setting in both cases.

Can you help me. I  can relevent details if u require.
I will really appriciate aearly reply

Regards 
Haresh

hi kelvin. thanks for tutorial. how to read the com port ?

[sebolek]

Very good tutorial. If you can make another/biggest tutorial I will be glad for you.

[KelvinLeUT]

I remember back in the days when I wish there was more tutorials like this.
VS C# is a great software that can integrate embedded systems to the end user.

Hi sir, nice work on serial communication. Can you make another video about Ethernet communication?

[juvanerik]

Nice tutorial, really helped me. Could you just please explain how you managed to get putty and your app to communicate?? Did you physically connect your PC ports? Thanks.

Hello friend! Could you help me to build a program which it needs to read a serial port connected a printer ? I need to get data about spooler's printer or all information that can be printed on a paper !

[yowassup]

could you show how to receive data from serial port for different size of data. 1 byte to 4 bytes.

[kingmcbrian]

duuuude you are so freaking awesome to me right now :D

[KelvinLeUT]

you need two usb-serial adapters
each will be assigned to a specific com port
they are really cheap on ebay
get the CP type and not the PL type

[carlosbarberis]

Thank you so much !! Where could I download the source code for both the C++ and C# applications for the serial port routines

[macxfadz]

Thanks for your tutorials..Keep up your good work brother, , :D :)

[samosamealoo]

any tutorial for wpf in respct to communication with usb ??
