RX 18 -> yellow -> green TX 19 -> blue -> white

Cool fonts I like:

• u8g2_font_bubble_tr (really cool for splash screens)
• u8g2_font_helvR10_tr (very readable, should really try this one)
• u8g2_font_6x12_tf (monospace)

Weird font rendering stuff going on

When the cursor is set to a position, the text will actually render from the left bottom corner, so 0,0 will actually render text that can't be viewed. Solution, for now:

U8G2 u8g2;
u8g2.setFont(u8g2_font_9x18_tf);
int ascent = u8g2.getAscent();
// will probably vary from font to font tho, right now I'm using
// monospace and that's enough
