Hi, I got some PIC 18F452's today, and having never used the 18 series parts I have a couple of questions; 1. Does anyone know if PicStart Plus with 2.3 firmware and MPLAB 5.3 will program the 18F452? I'm just about to install the PicStart 2.3 firmware, but the help file that comes with it is sketchy on the 18F parts. 2. Is it worth learning the 18F instruction set? I know the main use of these chips is for larger projects which suit a higher level language, but i'm more interested in having the extra processing power especially once the 18 and 8 pin 18F chips are obtainable. Any other tips etc are appreciated. :o) -Roman -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
