Hi Mark,
I'm sorry i misunderstood that you were certain of the cause. I have not got back to you because I had made a couple of line changes to the code and the problem went away for a few days, but another line change and its now back again, in a different place. It is hard to repeat consistently. I downloaded the beta at home, and will copy it to an Sd and bring it to work to try next week.
regards

Questions about the beta should be directed to support. This is really off topic.
But to answer the Q (this time) : you need to change the access rights of the chm file.
Try what happens if you launch it from explorer.
Otherwise check the settings that you indeed selected chm and not hlp

For the record : The beta did not come with a new chm only a new pdf. So i guess you forgot to copy the bascavr.chm file when you made a new test folder.

for some reason search on my project did not find all lpm code when i changed it many years ago.
but like i wrote before , this is different. it is likely the rampz gets a wrong value at some stage but i do not like guessing. i like some code to look at. |
Hi Mark,
I actually come back with this problem. After reorganizing my programm I never exceed the 50% Flashrange of my XMega128A4-AU.
But right now I am getting over the 50% Flash usage. My LCD will show bad graphics if I step over this limit.
If I remove some code, a included picture or an font file (doesn´t matter WHAT will be removed) and the 50% will not exceed,
everything works fine again. I really have no idea any more. As the Project is very big and contains some sensible data, I would
like to send it to you instead pf posting. Will it be ok?
BR,
Jens |

you can best write to support. but i do expect you have tested with the latest version. include app files (zipped) and mention version and serial.
the Xmega is special since it uses rampz for both elpm and memory access. this means that rampz need to be set to the proper value for normal ram access too.
So this is some other problem.

Dear all,
Mark spend a couple of time to find the problem. It was inside my code.
I use the graphics fonts from Evert Dekker in the updated version from Mladen (runs 15-20% faster).
This version uses loadlabel to load the used Fonts. The variable is declared as a word which does not
contain the page adress. This is the point where the graphics on the lcd gets distorted.
I will ask Evert / Mladen if they can fix this problem in their code.
BR,
Jens
EDIT: Mark awakened my ambition and with his tipps I changed the code from Evert / Mladen.
You need to change the following line:
| Code: |
Dim Font_adress As Word
|
to
| Code: |
Dim Font_adress As Dword , Font_addressp As Byte At Font_adress + 2 Overlay
|
If you switch the Fontsets
| Code: |
Font_adress = Loadlabel(font6x8)
|
just change the line to
| Code: |
Font_adress = Loadlabel(font6x8) : Font_addressp = Rampz
|
afterwards you need to change all variables which calculate with the variable Font_adress from WORD to DWORD.
After I changed everything the lcd will distorted again (more than before).
Than I found in the Help of Bascom the following line:
"Cpeek() is limited to the first 64 KB of the code memory. For processors that have larger flash code memory like the Mega128 (128KB) you can use CpeekH()."
Ok, after that I changed all CPEEK to CPEEKH and finally it works now perfectly!
Thanks again to Mark for the great support within the last 2 days!
BR,
