Help with assembler (Resolved, thanks)

Onni

I simply don't get it.

I am trying to write a servo pulse width reader in assembler. So I can send steering·commands to the propeller from my RC-controller.

This little piece of code works:

waitpeq Mask,    Mask
mov     Data0,   cnt
waitpne Mask,    Mask
mov     Data1,   cnt

And then I output (Data1 - Data0) in Spin in another COG to a terminal and se the values change from 1.2 - 1.7mS·when I move the stick.
Great!

But I really want a time out in the waitpeq. If the·transmitter is turned off the signal goes flatline and I want to do other things in this COG.
So I try to break the waitpeq in to pieces so I can insert time out code:

ch0                     test    Mask,           ina         wz               
             if_z       jmp     ch0                                 
                        mov     Data0,          cnt                                                               
ch1                     test    Mask,           ina         wz            
             if_nz      jmp     ch1              
                        mov     Data1,          cnt

But this code doesn't work! Why?

Because you need a '#' in front of your labels in the JMP instructions?

ch0                     test    Mask,           ina         wz               
             if_z       jmp     #ch0                                 
                        mov     Data0,          cnt                                                               
ch1                     test    Mask,           ina         wz            
             if_nz      jmp     #ch1              
                        mov     Data1,          cnt

Yes, you are right!

And the sad part is that I knew that [noparse]:)[/noparse]

Thanks!
