It seems that I may be out of luck here, but I'll ask anyway. I am using a GLK24064-25-GW display.

I want to take a snapshot of a number of live screens for use in the user manual. Since I see no commands to download a display image or copy it to internal storage, the only way I see to accomplish ...

I am also noticing an anomaly that may or may not have been seen before because I may communicating to the display in an obscure manner. I am using the command 'Drawing a Bitmap Directly' (0xFE 0x64) to draw an entire screen-filling bitmap (240 x 64, 1920 bytes) at 115,200. I would expect that ...

I am trying to re-create an off-the-shelf condition for the GLK24064. The command 'Turn Flow Control On' (0xFE 0x3A) has two parameters: almost full and almost empty. Can you tell me what are the default values for these two bytes?

EDIT: Ignore the above question...I see that Flow Control is ...

My display is GLK24064. I want to calculate the absolute pixel position of a character. Are the font metrics values based on 0 or 1? In other words, is the leftmost pixel of Left Margin 0 or is it 1. And is 0 a valid value? Thanks, Vernon.

Grab the latest version...

This will resolve the issue. Thank you.

...'invert font' checkbox in the upload pane?

It appears that there might be a later version of MODG#, because the 'Upload to device' in the Fonts section does not contain such a checkbox. There IS an Invert checkbox in the 'Upload to device' in the Bitmaps section. I see no version information ...

...for what purpose would you need the mgf format?

There is another message in this forum that describes a portion of the MGF file.

I created a new font based on Small Fonts available on another page on your website. The only difference is that I inverted the colors using a paint program, and ...

I am using the GLK24064-25 2.0 display. Is the MGF file format documented in this manual? If not, can you point me to a manual that has it? Thanks, Vernon.

Now if you need to find out if the manual override is left on, as Troy suggested, turn the auto repeat on to typematic...and what you will find is that the display will keep reporting the value 0xD5 (0x55 with bit 7 set to indicate there are more keys to read) if manual override is still on. [/b ...

It is true that the unit does transmit a key press of 0x55 when the jumper is placed on the Manual Override pins (R5-C1) while the unit has power. However, it does not have any key press data if the pins are already jumpered when the unit is powered on. The latter scenario was what I was looking to ...

Can the Manual Override jumper across (R5) and (C1) be seen by the Poll Key Press command (0xFE 0x26)?

Found the issue, Raquel!

The Change Baud Rate command needs a delay after the command is sent. I tried one second and the code now talks to the display. I can you provide a delay value once I test several permutations.

Vernon.

I reset the Data Locks. No luck. To insure the Rabbit RCM3200 microcontroller was changing speed, I measured one data bit; it was approx. 8.6 microseconds, which is the 115.2K bit width. Here's the code I used. It prints company info for the 19,200, but not at 115,200.

(BTW, I have seen this work ...

I got garbage [>BB@]. Do I need flow control?

> ...make sure that you re-initialize your port to 115200...

If I get your drift, the processor should change baud rate after sending the command.
Here is the actual code, starting at 19,200.
