ssd1306 Include Question

[PaulMaker]

Greetings,

Have been using Richard's include for the SSD1306 (32*128) display with sucess.
I was now trying to display a single dot which would move on the display according to an X and Y coordinate variable.

Using the command GLCDDHL 0,0,1,1 works to display a single dot and for a fixed X and Y value but not if I want to use something like Xvar and Yvar.

How can I do this?

Thanks

I was now trying to display a single dot which would move on the display according to an X and Y coordinate variable.

The ssd1306 has no support for setting individual pixels because the smallest write sets 8 pixels as a minimum and the i2c versions have no method to read back displayed data.
so my small footprint models that have no display buffer cannot support single pixel writes in any practical way

the fully buffered graphics versions can do it easily.

gl_setdot: 'Set a pixel to colour given gl_x,gl_y

ie set a pixel @30,33 and clear pixel at @31,33

gl_y=33
gl_x=30
colour=1
gosub gl_setdot
gl_x=31
colour=0
gosub gl_setdot
gosub show

Thanks Richard for your reply,

I was trying to do something like the image attached where it's used one of the small SSD1306 displays.
Is there a workaround to do something like this?

There is no workaround needed. Use the full feature version
