Momentary mode help

[tibbu]

Hello binu sir,

I am building a RC5 remote control in BASCOM8051 i am able to get latched output from microcontroller but failed to get momentary output from it. i need to drive my land rover from RC5 remote. pls help me what logic i should use to get momentary out put. i am using the sample code.

Thank you so much.

Use the Toggle bit from the Address byte. This bit toggles for every key press.

yes sir but the i can't understand how to use toggle bit to get momentary output. since the toggle bit remain same until next key press. and yes if ir receiver miss a key press the toggle bit will be same next time.

Here's the code

Dim New As Bit
Dim Command As Byte , Subaddress As Byte , Tempadd As Bit

Reset Tcon.0 'triggered by rising edge
On Int0 Receiverc5
Enable Int0
Enable Interrupts


Do
If New = 1 Then 'received new code
Disable Int0

If Command = 01 Then
cpl P0.0
Elseif Command = 02 Then
cpl P0.1
Elseif Command = 03 Then
cpl P0.2
Elseif Command = 04 Then
cpl P0.3
Elseif Command = 05 Then
cpl P0.4
Elseif Command = &H0C Then
P0 = &HFF
Elseif Command = &H0D Then
P0 = 00
End If
New = 0 'reset new bit
Enable Int0
End If
Loop


Receiverc5: 'interrupt routine
'the getrc5 routine uses 30 bytes ! of the stack for measuring
'the interval between the bits
Getrc5(subaddress , Command)
If Subaddress.5 = Tempadd Then
New = 1
Tempadd = Subaddress.5
cpl tempadd
End If
Subaddress = Subaddress And &B00011111 'set flag
Return

Sir this is unbelievable that how fast u r replying u r really so helpful . a lots lots of thanks to you. i will implement the above code and reply you soon.

Sir above code is also working in latch mode . i need output til i keep a button pressed.
Thank you so much.

hello sir pls reply to my post

[tibbu]

Anyone please help me

[tibbu]

Sir any hint for getting momentary mode.[?]

[tibbu]

sir how to monitor that the IR signals are continue or not.[?]
