Hello,
I try to marry a ssd1306 I2C oled-display (128x32 pixels) with a PIC16F1509, but the compiler comes with an error?
Why does this not works? The cpu have 512byte sram on board. How much does the component need?
Please have a look to the attachment...........


greetings

Jorg

Hi Jörg

128 x 32 = 4096 pixels / 8 = 512 Bytes to host the LCD pixel buffer. e.g. all of the RAM on your device.

Unbuffered display components do not require a pixel buffer by allowing the display to host it's own buffer. The requirement for this to work is that the pixel data must be able to be read back from the display.
