Ok, now that I learned how to interface with the buttons, screen, and LEDs, it's time to make an operating system! I'm currently working on one I call Anova OS (it's all text based graphics, sorry, I don't know how to do graphics yet). So far I have gotten the title screen finished! Pics coming soon. EDIT: 666 posts

Make sure to not destroy your LEDs with too high voltage. Also I know you have transistors to regulate the voltage, but last time I messed with them with my friend in electronics it was rather complicated and a PITA.
When I didn't know anything much about electronics, I hooked an LED up to one of those huge lantern batteries...it was supposed to be white, but it was orange, then brown, then really really bright, then poof. It started smoking and smelling really bad.

I got it working! Here's a vid:

I have that problem solved (by including the library file for this board) but now i have another problem. For some reason, the LED o the board is not lighting up. I did everything needed, programmed the board and released it from reset...but the LED is just not coming on!

Ok guys, I am in need of some help. I got the correct compiler required for this board, and I tried to build a simple program that would turn on an LED on the board. Here is the code, checked and double-checked with the documentation: #pragma config FOSC = INTIO67
#pragma config WDTEN = OFF, LVP = OFF
#include "p18f46K20.h"
void main(void)
{
TRISD = 0b01111111;
LATDbits.LATD7 = 1;
while (1)
;
}I click Build All, and I get this error: Error - could not find definition of symbol 'TRISD' in file './led1.o'. TRISD is a variable that is defined in p18f46K20.h. For some reason, it says that it's not defined. Here's the line in the header file: extern volatile near unsigned char TRISD;I have no idea what's happening here. Can anyone here help?

Yes, yes, and yes. It's just too blocky to actually enjoy.

So I guess no one could make an Acorn System 1 emulator? Or would no one use it (except for me) and it would be a waste...

I has gots a PIC18F4XK20 Starter Kit board! This is a dev board-like device powered by a PIC processor. It has 4 buttons, 2 pots, audio in and out, 8 LEDs, and an OLED 128x64 screen that you can interface with. I'm hopefully gonna start programming it soon. Here's a pic:  It also came with the PICkit 2 Programmer device (that's also the power supply). The cord that came with it to connect to the computer is bright red. Mom says she likes the bright red cord best, even more than the board itself.  Pictures of it running programs coming soon (as soon as the IDE finishes downloading  man my internet is slow).

Yeah, that looks about right. Don't forget about the buttons and upper screen

Hm, that's more than I can afford. But those are rare calcs.

I think an Acorn System 1 emulator would be really cool! Let me tell you what an Acorn System 1 is, especially for: <DJ_O> Spyro543 what is an accorn system 1? Does it makes you lose the game with GoldenAccorn84 casino ads via a spambot?
It's an old system that you programmed directly in hex. Also its only display is hex. It can store and recall data from a standard audio cassette. Here's a pic.  For more info, visit http://en.wikipedia.org/wiki/Acorn_System_1. An emulator of this on Nspire would be awesome!
