Hello,

Please dont laught! I'm trying real hard to learn this asm, I have used C, visbas, pascal etc in the past. I'm really liking what ASM i've learned so far.

I've got a MHS 80C154 40 pin Matra Enhanced 8052 Oki compatable MCU on a bread board with a 24mhz crystal. Powered from a +5v reg and I have 3 Leds getting their ground from p1.0 p1.1 p1.2. My problem is that I cant get it to work, if someone could look over my ASM and tell me if its ok then I know its my hardware, at the moment i'm really not sure. I've waisted hours and hours, and many eproms.

Thank you for you help,

Matt

I'm kinda lost....isnt that a pic of an EProm?

Here is his code. dont you need to have a starting place for your code? like you have to tell it to start at 00002$

INCLUDE 8051.mc
CLR 090h
CLR 091h
00002$: NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP ADD A, ffh JZ
00003$ JMP 00002$ ; turn on 00003$:
CLR A SETB 90h 00004$: NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP ADD A, ffh JZ
00005$ JMP 00004$ ; turn on 00005$:
CLR A CLR 90h JMP 00002$

Since it looks like you are trying to learn here is some assembly that might be helpful for your reference. I wrote it last year for a class. its the simplest assembly I have here. Note that some of the instructions ands stuff will be different because this is for a motorola HC-12 microcontroler.

your asm is fucked. I'll take another look at it later.

thanks for looking, I have made null progress still. Can anyone recomend any good books or web sites that may help me?

I have bought a couple of 8051 books but all the programming examples are in C.... which is very useful

http://www.8052.com

I learned practically everything I know from that website and from reading the pm6 source code.

ditto. 8052.com rules.
