Earlier:
Q:the SFRs .....Have a look at what you set and what you get

A:The values remain at 0

Now:
Q:.... MOV P0M1,#10001110B
....what does p0m1 show

A:That works fine.

One is bullshit, which one

I think i mentioned that the problem is configuring the A/D registers not the Port 0.
The registers i do not manage to configure are

ADMODB
ADINS
ADMODA

ADCON1

Therefore the A/D does not work.

Ok, I give up

"Ok, I give up"

He has told you that the registers beginning with 'P' change their values in accordance with what is written to them, however the registers beginning with 'A' do not.

then taking what I suggested and do it with a P register should not be rocket science. Spoon feeding is over.

Erik

I have tried what you have suggested with all the registers and still does not work. The instructions wark fine are the port configuration registers, the A/D do not accept the required configuration values.

Is this a bug on the EPM900?

I have tried what you have suggested with all the registers and still does not work.

I never asked "does it work" I asked "what is the result !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

This is why I posted "I give up" I ask "are the apples ripe" you answer "the dandelions are yellow"

Erik

Here goes your straight answers:

A first shows 2F then 8E
P0M1 shows 8E

What is your next suggestion?

It was stated above that the 'P' registers work but the 'A' register do not.

So, WHY do you give me an answer about a 'P' register?

This is NOT! trying to "make it work" this is "find out what does not work"

Erik

Call it whatever you want. The fact is that i can not get it to work because i do not know where the problem resides, LPC933 or EPM900 and how to overcome it. That is the reason why i am asking for technical support.
Can you help?

I think Erik has been patiently trying to help you but you are not giving him the information is is asking for. With this information he may be able to determine where the problem is. You may be able to learn from his approach if you cooperate.

The A registers maintain the values inaltered, at 0

I state:
This is NOT! trying to "make it work" this is "find out what does not work"

You reply:
"The fact is that i can not get it to work because i do not know where the problem resides,"

Once more I ask you to do something in order to narrow down what the problem is and you reply "i do not know where the problem resides". NEITHER DO I (and based on the lack of other responses neither does anyone else)

So I am suggesting a debugging technique for you to work by - I know, I should build a copy of your board, buy the same emulator you use and find out here the exact cause of the problem you have and then come back with an answer that makes it easy for you.
That is not going to happen unless you pay me a hefty consultant fee, however much you wish. My Keil/Ceibo combo does not have the problem.

If you want ANY more support from me for free, go through the steps I suggested above for a "failing SFR" and post the answer to the questions by copying the question and adding the answer.

I am trying to help you so, if you are not willing to work with me, why should I continue.

Erik

I was stupid enough to come back after saying "I give up".

An absolute statement

If you respond in ANY way other than replying to my questions and NOTHING else, this is my last post in this thread.

So it does in many places in any code.

STATE THW QUESTION YOU REPLY TO TOGETHER WITH THE ANSWER.

I assume this was entered at the same time as my post above.

Hi Erik,

Apologise for any misunderstandings.

I have managed to get the A/D to work. My problem now resides with the following:

I do not manage to set PT0AD after i perform the following instruction

MOV PCONA,#11101111B

MOV PT0AD,#00000010B

PT0AD does not assume the new value
