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!

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.

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.

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.
