The original Mikroe-SMT32F4 board as an on-board MIO283QT-2 TFT LCD that can
be configured and used. This is a 320x240 resolution display with color
capability to 262K colors, though the mio283qt-2 driver in NuttX only
supports 16-bit color depth, or 65K colors. Changes to both the
mio283qt-2 driver and the driver interface layer would need to be made
to support 24 BPP mode.
UPDATE: New boards now support a MIO283QT-9A TFT LCD that is not compatible
with the MIO283QT-2. It uses a different LCD controller. The default in
all of these configurations is the MIO283QT-2. But MIO283QT-9A is also
supported and you can switch from the MIO283QT-2 to the MIO283QT-9A by simply
modifying the NuttX configuration
