Thanks for running it That’s getting worthwhile then. Using Pauseus in the first post would have added code to it.

I might as well have a shot at the serial input over the next few days then.
Basically I did this on dspic in C, and it wrote easily into PBP as well.
The pic at the receive end is supposed to be 16F628A in PBP/asm.

My mp3 player serial spits out the artist & title info from the ID tags as tracks are skipped (that much is working).
Then the 16F628A is supposed to receive the serial, and transmit IR to an electronic sign the same way a user would normally use a remote to reprogram the scrolling message

This time going for serial input of a string terminated with either 0x00 or 0x0D (or any value below 0x20 really) into an array.
So far one byte, and untested, but I do have a PBP program on 16F628A ready to test and use it when done.
It’s on the receive side where I want serene replaced because I can keep going with my own data until the program memory is full.

rxbyte var byte
count var byte
delay var byte
shortdelay var byte

delay = 100 ‘ actual serial timing
shortdelay = 50 ‘ time/2


serinbyte:
IF PORTB.1 = 1 THEN
‘ optional countdown to timeout here
GOTO serinbyte
ENDIF
pauseus delay
pauses shortdelay
FOR count = 0 TO 7
rxbyte.bit7 = PORTB.1
rxbyte = rxbyte >> 1
pauseus delay
NEXT count
pauses shortdelay
rxbyte = rxbyte ^ $FF
return

i'd bet this won't stack_up any better than debug either as is

until the program memory is full.

sram ?

Storing data in program memory until full yes.

Probably not like this, but I'd rather have the whole thing work in PBP
before doing any of it in asm.
Hserout of course will beat both of them,
but sometimes you want all eight bits of Portb for something else.
