definitions for OLEDs that are orientated landscape

[StefanL38]

Hi,

I have this 64x128 OLED-display. https://www.waveshare.com/wiki/1.3inch_OLED_Module_(C) If I use your Display-Option rc = oledInit(&oled, OLED_128x64, 0x3c, FLIPPED, INVERTED, HARDWARE_I2C, SDA_PIN, SCL_PIN, RESET_PIN, 1000000L); The shown picture is in portrait-mode letters are readable in the 64pixel-direction while it should be in the 128 pixel-direction.

This means I have the display in front of me in landscape

            width 128 pixels

But the letters are written vertically. And what is not correct in my textdemo above all the letters are rotated 90 too.

What would I have to modify to add a displaytype that shows the characters in the 128 pixel-direction?

This means the basic pixel-locations must be rotated 90 degress.

best regards Stefan

Hi Stefan, I don't currently support that display in my ss_oled library, but I do support it in my OneBitDisplay library. ss_oled is deprecated in favor of using my OneBitDisplay lib which is still actively being developed. For OneBitDisplay, you would use the constant OLED_64x128. The memory is oriented 90 degrees rotated from the way the display is normally used. In order to display text along the longer axis, you would need to have a RAM backing buffer and use the obdScaledString() function to draw at 90 degrees rotated.
