I think it's because the Maple uses a different set of pin names to the actual STM32 pins. You'd need to use
D0..D33
(I think) - the mapping is this one: https://github.com/espruino/Espruino/blob/master/boards/MAPLEMINI.py#L63-97 -

I tried to use I2C1.setup({scl:D16, sda:D15})... PD16 and PD15; P16 and P15; PB6 and PB7...
these values result in an error:Uncaught ReferenceError: "PIN" is not defined
where PIN is D16, PD16, P16, PB6...

Wiring LCD -> Maple Mini:
GND -> GND
VCC -> Vcc
SDA -> PIN 15 (I2C1 SDA)
SDL -> PIN 16 (I2C1 SDL)
Code:
