New LCD drver glitch

diego

Hello,

With the new LCD driver, the GRD_COLOR seems to be "hard coded" on the driver itself.

The problem is the __Erase_Color function is always restoring the grid to that hard coded value.

I've checked the old driver assembly, and it declares an extern grd_color variable, which does the trick! (no problems on the old LCD)

Did you change the name of the variable on the new driver?  Do you know how can I tell the __Erase_Color function the current grid color, so it restores it correctly?

Thank you!

What is the firmware version of the APP you use?
The grid color is always show, you will display after erasing.
You can study first Display. S program code.
What is on screen screen?7781 the screen?

Sorry for the late reply...

Let me explain better:

screen is 9341, firmware upgrade version is V3.26A

On our app, we have the option to change grid intensity. If you change the grid intensity, and then move a cursor for example, the grid color restored is the original grid intensity.

I do not know how to explain it better...

the assembly __Erase_Color function, restores the grid color to a hard coded color, instead our custom grid color.

You mean, you in the development of firmware, the color of the grid not defined?
You can be in the Display.s  file change color inside, or don't use  Display.s  function.
Your can writing display function.

I do not have any Display.s, I have ASM_Functions.s and the changes I made there are not being transferred to the scope.

We are using the latest bnf firmware...
I've patched it when the new lcd came out, I do not remember exactly what I did however.

BNF the firmware is not the official firmware, we don't know how to write programs, is the author of BNF you do or consult the author.
Or you can consult, according to official firmware function.

I know, I am asking about the LCD driver which seems to be already there, (is it in the bootloader?)   Since the same app we have works good with old lcd driver and have this issue with the new lcd

Yes the newer devices have all the LCD related functions in the Bootloader area.  The Firmware simply uses a vector jump table to call those functions.  You could try attach your custom __Erase_Color function at the end of the firmware and call it instead of one in the bootloader.  Are you making a port of Benf to run on newLCD, someone already did.
