Send data PIC to PC
Hi,
I'm doing a program for viewing data from Pic to PC and backwards.
When filling the fields of TextBox in VB6 application and press the "Send" button I see on the display the data correctly.
But when it comes to receiving the data to be invented in the Subroutine "EnviarDatos" the Pic not visualize anything in the TextBox.
Here I leave the program for the PIC and the subroutine VB6 "OnRead" for you dig where you're going to have a look at the ruling.
in this line means: USBIn 1, USBBuffer, USBBufferSizeRX, DoUSBIn
The USB 1 it means?
ahhhhhh......
When I put the command "USBInit" the computer does not recognize USB pic.
But when I remove that command, it does not recognize but I have to put "GoSub DoUSBIn"
Thanks again ....

Sorry, either you are on the wrong forum or you are using the wrong basic.
This is a Pic Basic forum.

Send data PIC to PC
The program is written in Basic PBP (mecanique) Crownhill Associates. The last part is written in VB6 in order that you observe the process of the program.
I do not understand the problem ...
Thanks

PBP is not from Crownhill.
DIM and DECLARE are not part of PBP.
As far as I know.....
Maybe PROTRON ? PROTON ?

konter you have an array of text1(n).text boxes and, with your VB code, in every box you transfer just one byte, so you must have all the boxes on the form to see something.
Code:
Text1(1).Text = BufferIn(2)
Text1(2).Text = BufferIn(3)
Text1(3).Text = BufferIn(4)
Text1(4).Text = BufferIn(5)
Text1(5).Text = BufferIn(6)
Text1(6).Text = BufferIn(7)
Text1(7).Text = BufferIn(8)
Text1(8).Text = BufferIn(9)
It is much better with one single text box
Code:
Dim I as Integer
Text1.text = ""
' first byte is the report ID, e.g. BufferIn(0) so you start with 1
For I=1 to 9
Text1.text = text1.text + BufferIn(I)
next
In the above example you will have all the bytes nicely added to text1.text box

Thanks for the clarification, well I put it with intent for all who would help them to understand, because if everyone does not know how to program in VB.
Anyway still not working,
I put a Timer every 1ms buffer but I read nothing at all, for me the bug is in the sequence of programming the PIC, but no where with. "GoSub DoUSBOut" or "Gosub DoUSBIn" I've changed so many ways not to do.
For the program to read the VB inside PIC and see it in textBox.
THX
