if you use canned routines, how much more difficult is USB than MOV SBUF,A? The USB routines vary depending on which manufacturer's MCU you use. MOV SBUF,A works on any 8052-compatible MCU. The USB code that works on TI's MCUs is not the same as that which works on other MCUs. It is similar (from what I've seen since I read a book that explained USB on Cypress' device to understand the TI device I was writing code for) but just different enough to make you think you'll be better off modifying the existing code than throwing it out and starting over. It'd be great if manufacturers of 8052 derivtives that support USB could get together and standardize the SFRs used to configure and operate USB. If not by SFR address then at least by SFR function and name. isn't the USB connector easier to use than DB-9? ... For the user of an end-user device purchased at Best Buy, yes. As a complete substitute for all uses of RS232? No. Regards, Craig Steiner |
