Hi HB'ers
I have been using the sony-ir.asm program written by Brian Silverman to
send commands to my mobile HB. However, I noticed that if I use printf
commands the ir routine returns un-reliable results. My program uses the
subsumption approach (see Mobile Robots, Chapter 9), so all the rountines
are runnig using start_processes. However, sony-ir and printf work fine
when executed sequentially.
sony-ir.asm uses the subroutine_initialize_module to insert itself in the
millisecond isr.
The only way I can get reliable ir decodes of my Sony remote is to comment
out any printf calls - not a big deal but hinders debugging.
Any ideas why??? I thought the subroutine_initialize_module isr was not
interrupted.
Keith
PS I am using the "stock" HB IC setup - no other isr's other than
lib_hb.lis loads and sony-ir.lis
