config MICROBIT_DISPLAY
bool "BBC micro:bit 5x5 LED Display support"
depends on BOARD_BBC_MICROBIT
depends on PRINTK
depends on GPIO
help
Enable this to be able to display images and text on the 5x5
LED matrix display on the BBC micro:bit.
if MICROBIT_DISPLAY
config MICROBIT_DISPLAY_PIN_GRANULARITY
bool "Access the GPIO on a per-pin instead of per-port basis"
help
By default, the micro:bit display driver will update the GPIO
pins of the display (pins 4 through 15) by accessing the entire
GPIO port. This is done for efficiency, however it may interfere
with other peripherals connected to the same GPIO port. Select
this option if other peripherals are connected to the same GPIO
port.
config MICROBIT_DISPLAY_STR_MAX
int "Maximum length of strings that can be shown on the display"
range 3 255
default 40
help
This value specifies the maximum length of strings that can
be displayed using the mb_display_string() and mb_display_print()
APIs.
