Blitz (90/119)

Subject:cia timing

This CIA timing thing Ants made works well. But it`s only allowing an asm
interupt handler and can`t use Blitz variables. Is there a way to use Blitz
variables/commands or go around it and use some pokes or something?

I am currently using setint 5 as interrupt handler to run the necessary code
in and using the timer/resttimer commands from riamoslib, which uses a CIA
timer. It works well. But doesn`t offer enough granularity(it fires every 1/50
of a second) to raise/lower 1 bpm at a time. It raises like 7-10 bpm. And
ofcourse the stint 5 itself only uses 50 or 60 Hz. But it`s a nice fix until I
get proper timing/interrupt settled.

As a side note, I read some docs on devcd2.1 and it says to always use
CIAB-timer B if possible. In the RKRM this had been told incorrectly.

Regards
