 Posted: Fri Aug 04, 2006 1:20 am Post subject: Inkey OR Ischarwaiting |
 |
|
Hello all ...
I am working on a serial prog and got some confligts Mega32
I use Config Serialin = Buffered , Size = 254
and it works fine for B = Inkey()
talking to my gsm phone
but i have a terminal on same port (only 1 serial) i M32
it is calld by set portb.0 =1 relay shift off phone from RX/TX and connect terminal to RX/TX
in terminal mode i use Ischarwaiting()
but here my problems start do to Config Serialin = Buffered , Size = 254 I THINK
is ther away to set Config Serialin = Buffered , Size = 254 off while terminal is in use ?
or what can I do ´
in terminal mode i send (1 char) to navigate in to menu then i use INPUT do to sub menu
can i fix this problem ? or do i have to stop using the ( 1 Char send ) in menu ?

Seems like an awfully large buffer but, OK... as long as it works for you.

Not easily, No

I don't understand what the problem is? Post some of your (1 char send) menu code to further explain.
I am just guessing..., but are you trying to say that your problem is because the INPUT statement waits for a carriage return and line feed before it will move on to the next line of your code? Or maybe your problem is that the INPUT statement echos characters back at the terminal? |

Cls
Lcd " Wait setup running"
Call Ee_menue
A = 0
Smsc = ""
Print
Print "Enter command 0 = exit > : "
Do
A = Ischarwaiting()
If A = 1 Then
Getcr Agr 'filter out Cr Lf
Clearbuf '´(emty buffer and get string if not emty for gsm )
Waitms 200
Select Case Smsc 'smsc is serialin from buffer
Case "?" : Call Ee_menue

End If
'IF

End Sub
Sub Getcr(s As String)
S = ""
Do
B = Inkey()
Select Case B
Case 0
Case 13
Case 10 : If S <> "" Then Exit Do
Case Else
S = S + Chr(b)
End Select
Loop Until B = 0
Smsc = S
Waitms 50
End Sub
Sub Clearbuf()
Kk = ""
Waitms 250
Do
B = Inkey()
Kk = Kk + Chr(b)
Loop Until B = 0
Waitms 150
End Sub

kimmi... in your example posting, you left something out that's kind of important or you'll get no terminal send chars...
| Code: | Config Serialin = Buffered , Size = 169
Enable Interrupts '<- buffered serial requires this line
Do
'... etc
Loop |
If you have that in your real code but left it out of your post, then I'll keep looking. |
