It requires a very simple modification to the G29. The display will seet between the base and the steering wheel and for the stock G29 paddles to remain functional, the steering wheel must be spaced.

I used simple spacers that I had laying around with OD≃8mm and ID≃5mm. They will go on the screws that screw the wheel to the base:

Roadmap

Better layout tooling
Dynamic layout/data

Debugging wires

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

Shameless begging

Hey, doesn't hurt to try, its free either way: Buy me a coffee!
