Hello Raquel, The font I'm using is the default one: Small Filled. I assume it has a fixed font size (I couldn't find in the LCD's data sheet a command to modify the font's size). In my first post I described the steps I did that caused the problem. Those were just an estimation of the steps, so her...

Assumption verified

I checked again and found that the following statement:
"Also, apparently that the text in action #5 doesn't get completely clear."
is actually true/correct.

How fast the GLK19264-7T-1U device can process commands?

I'm writing to a GLK19264-7T-1U device, and for some reason the the text isn't rendered properly. These are the actions I do: Send a "Clear Screen" command. (0xFE 0x58) Write 20-chars-long text. Waits 1 second. Send a "Clear Screen" command. (0xFE 0x58) Write 20-chars-long text. ...

Paradigm wrote:Unfortunately, depending on the display, both could correct. The most common display we sell is a yellow/green display, and when you draw, the 1-255 is actually black, while 0 allows the background colour through.
Oh, so how someone can distinguish if the data that he reads refers to his display?

GLK19264-7T-1U datasheet errata ?

I think that there's an errata in the DS of the GLK19264-7T-1U device. In the Description column of the "Set Drawing Color" command, the following text appears: Drawing color (0: White, 1-255: Black). But it actually should be: Drawing color (1-255: White, 0: Black). That's verified. Pleas...

Hi Ray, I would be able to try that later because of some technical reasons. Hi Raquel, I think that I already have a black background. I also tried to draw a black rectangle (command 0xfe 0x72) but it didn't work either. Am I required to draw a solid rectangle with an opposite color anyway? The com...

GLK19264-7T-1U color parameter problem

Helllo, I'm using the GLK19264-7T-1U device. It works great. But I have noticed that some commands do not get executed. For example, when I send a command that draws a rectangle with a specified color parameter (0 or 1 = white or black, respectively) - the command isn't being executed. I don't see a...

GLK19264-7T-1U and RS232 (TTL levels) communication

Hi, I have the GLK19264-7T-1U device. There's a communication problem with the device. It turns ON, but it seems that it doesn't detect the bits that I'm sending. I did the following configurations: Disconnected all 3 zero-ohm resistors from the RS232 jumpers, and connected 2 zero-ohm resistors to t...
