I do not know if this has been discussed before but I could not find much information about it. I worked on 16F877A for sometime and know about setting fuses, initial registers, setting digital/analog i/o etc etc. I am having big problems understanding the setting up of 18F4550. Are there any guidance/notes anywhere which can make it a bit easier to understand for not so technically inclined. Datasheet seems to be a bit complicated at this stage. Thanks in advance.
