Reference of undeclared function in OLED internal driver

[HJPearce]

in components/peripherals/ssd1306/nucleo-f429/oled_pixel.c, specifically on line 353, the function
ssd1306_WriteChar_(*str, Font, color)
(from oled_string.c) is used, despite not being included by oled_pixel.c or its dependencies.

It would seem that ssd1306_WriteChar_int should be used instead (which is defined on line 309 of oled_pixel.c). Please advise if I'm wrong.

Thanks, Hayden.
