To enable LCD debug output:
Device Drivers:
CONFIG_LCD=y : (Needed to enable LCD debug)
Build Setup:
CONFIG_DEBUG=y : Enable debug features
CONFIG_DEBUG_VERBOSE=y : Enable LCD debug
NOTE: At this point in time, testing of the SLCD is very limited because
there is not much in apps/examples/slcd. Certainly there are more bugs
to be found. There are also many segment-encoded glyphs in stm32_lcd.c
But there is a basically functional driver with a working test setup
that can be extended if you want a fully functional SLCD driver.
