Each character in the font ("glyph") specifies the dimensions and offset of the character, and also the "advance" - how far to move the cursor after printing the character. It seems to occur if the number would normally be > 127. The link cited by Sara above uses a custom print routine which checks the character value. The first release of the SSD1306 support library py-gaugette used the 5x7 pixel fonts from the Adafruit GFX library. At the moment the TFT_ST7735 library does not support the FreeFonts format, however the Mega and Due 16 bit libraries do. Just paste the content of a .h font file, extract the glyphs, and you can edit them one by one by flipping the individual pixels for each glyphs, changing the advance, offset, or modifying the baseline. tft.println("with my blurglecruncheon,"); I cant seam to get around with it.should i change the pin?
