Device configuration

[Dimebag]

Tom, I wasn't side tracked. I will move to PIC24/PIC32 after I understand C for embedded devices. I am asking for help to understand the basics of C/C++/Header/Linker/etc. I am looking at PIC24/PIC32 for later use. My knowledge base is very poor. In the meantime I just want to improve my understanding of the tech behind the complier. I understand the device I selected is out dated by the new MCU's standards. I am only asking for direction to advance my knowledge base.

PIC32 is of interest to me currently.

You need to get back to just blinking an LED or this will get out of hand. Ric suggested just using the built in __delay function that is in XC8, and that is a simple start.

Also, how are you seeing atmel parts as a compilation option?

hahaha, that's what the guy behind the sales counter tried to sell me. I was not impressed.

I think I did do that. I am not sure if it would program to device that way. I am unable to show evidence. Please select a device in which I am able to provide code for Blinking led.

If your going to select PIC24/PIC32. I will need the fuse configuration declarations. I will need a sample code as well to support.

You are being uncooperative, so I have to bail out here...

Hi Tom, I am waiting for the store to order some PIC24's, PIC32's. I will be hooking up a micro over the weekend to test the LED blinking program. At the moment I am using Proteus VSM to simulate the programs. BTW I have started using the delay_ms().
