AXE033 messages

It will be obvious that I am a rank beginner. So as not to be found a blind idiot I have spent more than a week trying to find where I am wrong, but I can't. I have copied and varied what is on Page 10 of the AXE033.PDF, which shows how to place a string into one of the 7 addresses available for my data. I'm using a 28X2 chip and an AXE033 serial led.

serout C.0,N2400,(253,1,"Player 1= ") is a line that is supposed to place the given data into the led memory 1.
serout C.0,N2400, (1) is supposed to show it on the AXE033 led.

I can't make it do the job.

I can write directly to the led with: serout C.0,N2400,("Hello!123"), so I must be doing something right.

Would someone write and test a correct method of doing it for me? It might just save my sanity.

Thanks for any positive help.
Welcome to the Forum.

Please copy and paste the following program,
keeping 16 characters within the " "

init: pause 500
serout C.0, N2400, (254,1) ; clear screen

pause 500

 serout C.0,N2400,(253,1,"Player 1        ")
pause 1000

 serout C.0,N2400,(253,2,"The final score ")
pause 1000

 serout C.0 ,N2400,(1)
pause 100

  serout C.0,N2400, (2)  
 pause 100
Let us know how you get on.

Oh dear. The results were as I have achieved.
The first input about "Player 1 " appeared on the Axe033 screen when it was supposed to be put into memory 1.
From then on the screen was empty.
I can manipulate what appears on the led, but no way can I get out anything that might be in led memory 1 or 2.
I'm pleased in a perverse way that I have company in my difficulty.

Can you or anyone else help me any further? There must be a solution!
Thank you. I have checked, and I should have said LCD, not LED.
I don't know whether my error changes the situation though.

I have checked a number of communications that deal with my difficulty,
but every time I follow a suggestion I end up still unable to read from the LCD's memory.
Is anyone out there able to show me that he/she can do what I cannot?

Maybe it isn't doable. Does Mr Axe033 know the solution, I wonder? How can I contact him?
FOr the AXE033, there are no changes available to the firmware as there are for the AXE133 series displays.

Unfortunately I am currently not at home and thus cannot test against my own AXE033 to help you - at least for some hours yet.

Are you absolutely sure you are using an AXE033 and not an AXE133 ?

This works for me using 28X2 and AXE033 ...

I am very pleased to have you help me also, Hippy.
Unfortunately, even though I used Ctrl C and Ctrl V to transfer your file
only your first line of text appeared, then the screen stayed blank.

On picaxe vsm the line appeared as a division sign (Hex B8) then a space, then your text only up to D.
On Picaxe Editor v6.0.6.2 your whole first line appeared.

I can't think that the beta version would be the cause.
I'm getting so fed up I'm beginning to study about parallel connections rather than serial,
but that's admitting defeat, and way beyond my ability to date.
Being a beginner causes all sorts of communication difficulties.
I have been under the impression that I am on a PICAXE VSM forum.
I have taken it for granted, but if I'm not, yes, I am learning to use VSM.

Many post in the incorrect forum areas and in the absence of any specific reference to VSM folks here though you were working with actual hardware. It pays to be very clear what you are working with.
I've always thought I was in a PICAXE VSM forum.
If I'm not I apologise.
Anyway, doesn't a VSM program do the whole job?
I spent a lot of beer money on it.

It looks like ec accidentally moved this thread from the VSM forum to the main forum, because it looked like you were using a real part.

We'll move it back.

What you are trying to do will work fine on a real chip. However VSM cannot simulate the embedded LCD messages, because there is no way (simulation method) to maintain them between simulations (ie you write them using one simulation, and then expect them to work in a another different simulation later on, but in reality they have not been 'saved' as each simulation starts new). Also the serial LCD simulation is an original Labcenter part, we cannot edit it's behaviour (as we can with the PICAXE chip simulations).
My thanks to all who tried to help me with my beginner's PICAXE VSM.
It appears that I can't do what I wanted to do with the programme.
I have started to learn how to use i2c on PICAXE VSM, and would you believe
I have already found that I can't do what I want with i2c either.
These are quite basic failings, because I am only a few weeks into the programme and can only work with the very basics.
I shudder to think what I'd find won't work if I progressed.
I am extremely disillusioned, and I feel I have been gulled into paying, for me, a goodly amount of money for a less than satisfying result.
If someone would tell me who to contact I'd deal with them directly, but in any case, thanks to all for helping me.

i2c works fully on PICAXE VSM e.g. for EEPROMS etc. and other i2c parts such as the DS1307.
Have a look at the i2c tutorial examples (via the Help menu) for some ideas.

However there is no i2c model of the AXE033 LCD, so use it in serial mode instead
Do not be disillusioned about the PICAXE system in general.
While the VSM software may not have fully met your expectations there is nothing stopping you experimenting with the real hardware if you have already purchased that.

I personally have never used VSM or similar software and undertake all experiments and coding direct to the hardware.
As your experience/confidence builds up programming can become second nature.
