Plex and I2C Words

Changed:

<
< oled-emit works like the standard word emit. It blocks the calling thread, as long as the character is not written to the OLED display (less than 300 us for a 6x8 character and 400 kHz I2C). Horizontal (x) position is in pixel (0 to 127), vertical position (y) is in lines, a line consists of 8 pixels. Larger fonts takes more than one line.
