I'm still converting code from sx28 to sx48, and looking for some tips with the following:

 

I have a word variable in bank $60 called TickTimer

Im passing a byte into the sub and have aligned the value to be in the same bank ($60)

 

 

Sub Setit

 

 tmptimerB1 = __PARAM1


   \ BANK Timing
  TickTimer = 12590 / tmpTimerB1
    TickTimer = TickTimer + tmpTimerW1
  \ BANK $00

 

ENDSUB

 

First of all, I'm finding that I need to add ASM bank statements in order for it to start right.

Secondly, when running through SXSim, the banks are not updatating to bank $60 to do the calculation correctly when accessing the TickTimer_LSB and _MSB bytes.

 

Do I need to go to assembly and add the necessary bank statments for it to work correctly? Note Bold code updates at BANK $00

 

Thanks again!
