I revised with the CJNE function for the checking routine. Less messy, works just as good too. I am learning.
CJNE R3, #128, Checkleft ; Compare R3 to 128. If R3 is less than 128, no trigger, C is set. Checkleft: JNC Trigger1 ; If C is set, no trigger, so do not jump. If C is NOT set, jump. CJNE R4, #128, Checkright ; Compare R3 to 128. If R3 is less than 128, no trigger, C is set. Checkright: JNC Trigger2 ; If C is set, no trigger, so do not jump. If C is NOT set, jump. I did have some problems at first because I was using JC and not JNC, then I realized the IR sensors are active low, which reversed everything. Also, thanks Jan, for that link to the ZIP file with the HLP in it. Thats pretty much what I needed; trying to get this 10yr old hunk of crap computer to load PDFs is... stressing. On a side note, don't buy or use "programming and customizing the 8051 microcontroller"; it makes way to many assumptions about your past with microcontrollers. Judging by Myke Predko's website, he didn't take this into consideration as he has many books on other micros. From his perspective as a writer, that makes it harder to write a book for beginners. |
