#110864 - re: about the code Responding to: ???'s previous message |
So the main question I have is while the serial data bytes are going into the buffer during the interrupt, the program can still run doing something else like program the bytes into the eeprom?
answer: NO, but when the ISR end, the "program" will be resumed. There is something here, this can NOT be your question, elaborate. If it is, get some veru basic litterature and STUDY. Ok, maybe I should have worded the question differently. I was just wondering if "the "program" will be resumed" properly or not, especially if the program was interrupted during a pulse OR some timing critical routine - OR a byte being shifted out. I understand how the ISR works, and have been reading and searching a great deal before I decided to ask any questions. Interrupt driven serial routines involve much more overhead as far as program code size and RAM requirements MUCH????? This is an actual quote from the pdf file "rs232gd.pdf" found on this site. |
