Display and input devices

The 240x320 TFT color LCD connected to port SPI3 of STM32F373VCT6 (shared with the
MicroSD card) and four general-purpose color LEDs (LD1, LD2, LD3, LD4) are available as
display devices. LED LD9 is connected with PA7 to show the status of comparator 2 when
debugging. The 4-direction joystick (U34) with selection wakeup button (B2) and key button
(B3) are available as input devices.
The LCD can be enabled by chip select signal PD2 and this signal should be set as open-
drain output pin in STM32F373VCT6. All joystick signals should be set as pull-down input
pin in STM32F373VCT6.
