Thread: Using Proteus Virtual terminal for sending data to PIC

I use ISIS 6.9 for simulating a communication between PC and PIC16F877A.
I want send data to PIC by using virtual terminal.
But my problem is ,the virtual terminal just send keyboard ASCII codes to output.
But i must send data like this "0x04 0xF4 0x01 ..." that the equivalent character did not found on keyboard.
Can i send text files by virtual terminal (like hyper terminal) ?

You would be better to use either the Pattern Generator Virtual Instument (will load a CSV file containing the bytes you want to transmit) or the file or pattern input generator.

Simply type 'cntrl A' for 0x01, cntrl B for 0x02... and so on. THis is working on the virtual terminal (switch it to hex echo to see).
For the he high values like 0xF4 (dec 244) use the alt 0244 as usual

Hope this helps

What if i need to send byte 0x00 ?

THanks man

Hi;

You are right, it's not possible in the VirtTerm window (unfortunately).

However, an "easy" workaround to this:
Use an other char instead of the null (for ex. a backslash '\') and make a simple converting routine
in your serial receiving sw to substituting it with a null character.

Great idea, i'm going to try that.

Are there any tutorial on how to send bytes to the virtual terminal using that Pattern Generator Virtual Instument , i don't undestand how to do that.

Thank's

I think it's impossible.
But ... hopefully you can be using the pattern generator INSTEAD of the virtual terminal as an input device.
I haven't tried it yet , study carefully the timing and clocking items in the pattern generator help.
Good luck!

how can i enable echo i'm searching the option and trying to add echo=1 ori something like this in property menu .. for over 2 h..

I had to do this once. I think I set up another virtual PIC and loaded a data table and conversion software into it. I then communicated with the virtual chip with terminal in ascii. This then converted it to whatever code I needed, and output it to the main chips ser in port. Was a while ago, so no longer have details.
"A" could be 0x00 "B" 0x01 etc, or whatever.

hi i am using proteus 7.1.when i want to transmit any character to serial port and to check i am using virtual termial,but the terminal show different character then transmitted one.my circuit is
