SSD1306 INCLUDE for PBP3

[lester]

Test Message - Please disregard

[richard]

if you wish to run the display in inverse colour mode at any time :
use one of these "usercommands" that are part of the include

to invert entire display
SSDC $A7
to restore it USE
SSDC $A6

Thanks for information

Richard, I am hoping you can help me with an issue I am having making your SSD1306 driver work. Everything is working well except when I display a bitmap with the y axis not set at 0 it cuts the image in half. I have tried with every version of the ssd1306_I2C.INC found in this thread with the same result. Posted here is the code with a simple 16x16 bitmap icon and an image of it displayed at both y=0 and y=4. Any chance you can help sort what is going on here?

Any chance you can help sort what is going on here?

yep, i never did test with other than 64x64 bmps, that masked the fault
now we know it works with 64x64 and 16x16 bmps at least

there is a defect in the include file, the bmp usercommand macro is not quite right

in the include file the bit in red needs to be added in

latest version

[spcw1234]

Thank you, Richard! That works perfectly! You have no idea how much time I spent attempting to fix that.

One other request. I am struggling to understand the macros but would like one that can do a point to point line. Something that would do x1,y1 to x2,y2. Can you assist with adding a macro to accomplish this?

[richard]

One other request. I am struggling to understand the macros but would like one that can do a point to point line.

not possible with this small footprint method , horizontal and vertical lines is the best it can do

if you want full graphics use this

[spcw1234]

I was afraid that would be the case. I have spent time playing with that version and can't figure out how to display a bitmap image, which is a requirement for this project. That's using DMDBMP command.

If I copy in the macro from this version and add the SSDBM command, I can display an image, but not correctly. Likely due to the difference in how the height differs from both drivers.

[richard]

post what you have tried and i will have a look

[spcw1234]

When I use SSDBM it shows the top half of the image twice, and seems to lock the display as I can't clear or alter what is displayed afterwards.


Using the DMDBMP format, it displays a black screen, but if I attempt to display something afterwards it goes nuts. I assume I'm not addressing the BMP data location correctly, but don't see an example or instructions on using a bitmap.

Here is the code I am running right now with the bmp. Doing it this way seems to get stuck right after the image is displayed, and it looks like the picture below.

That gets me closer, in the sense I figured it needed specified somewhere! But it doesn't correctly display the image. I have reverted back to non-edited include files. Thoughts? Thank you for your assistance!!!

[richard]

ah! the bmps are in a different format the byte are now laid out horizontally
i also discovered the dmp code upsets the font height [did have a shared variable]
i used lcdassistant to generate bmps

some files to play with

[richard]

glcd tools also works well in generating bmp's
and formats the data nicely

[spcw1234]

The only version of GLCD Tools I can find is 0.2. I have been using LCD Assistant, but I'm having mixed results. Do you have a link to download GLCD Tools 1.5?

This attached file has a few BMP's in it, the Logo64 opens successfully, except it takes 5+ seconds to display each image after the screen clear... The other 2 (StallIcon and OneIcon) both don't load and results in a bricked display until power cycle. I have tried other's and can't get them to open.
These were created with LCD Assistant set to horizontal and formatted appropriately.

I'm not sure the reason for the failed images to display,

I'm not sure the reason for the really slow load times to display the images

The SSD1306 driver this thread was created for loads images with excellent performance.

[spcw1234]

I resolved the slow load times by commenting out the debug lines in the sbmp subroutine.

[spcw1234]

I have found if I revise the first byte of the bitmap to = 0x00 instead of the value it should be, the image will display. Obviously missing the first 8 pixels worth of data though...

[spcw1234]

I have everything working, but using the SSDBM version for bitmap. This obviously required modifying the include files, but everything seems to be getting along.

I can share the modified files, but won't if you prefer as to prevent confusion. If you find a fix for the DMDBMP version, I'm sure it is a better solution.

Thanks for your work on this Richard!

[richard]

there was another bug in the include, the bpm height var was reading in the first byte of the image as its high.byte
when there was not meant to be a high.byte
and i did accidentally leave the debug messages active
i have updated the include in the proper thread

[richard]

i cant find the gltools on the web any more
i did find my install version in my downloads folder
at your own risk

[spcw1234]

Thanks Richard!
