Assembly Command Clarification
in Propeller 2
While reading through the assembly command list I noticed the REP command and got curious about its limitations.
Specifically, can one REP command contain another like in this example code for driving a neopixel:
Specifically, can one REP command contain another like in this example code for driving a neopixel:
rep #12, %[pixel_cnt]
rdlong %[thisPixel], %[hubPtr]
add %[hubPtr], #4
mov %[bit], #8
rep #8, #24
drvh %[pixel_pin]
testb %[thisPixel], %[bit] WC
incmod %[bit], #32
waitx %[tickH]
drvc %[pixel_pin]
waitx %[tickC]
drvl %[pixel_pin]
waitx %[tickL]

The second one should just cancel the first one.
There is no internal stack, or storage for multiple reps.
I am overwhelmed with P2 PASM. I still find goodies in P1 PASM, squeezing another 1-4 longs out of something.
