Connecting ILI9341 Display to STM32F446

flux

I can’t modify the project right now because execution is unavailable in this session, and your current access to this project is view-only. Nothing has been changed in the schematic.
To connect this ILI9341 SPI TFT display module to an STM32F446, the likely wiring is:

Table

Display pinSTM32F446 connection
VCC3.3 V, unless the module explicitly supports 5 V input
GNDGND
SCK / CLKSPI SCK, e.g. PA5 / PB3
MOSI / SDISPI MOSI, e.g. PA7 / PB5
MISO / SDOSPI MISO if used, e.g. PA6 / PB4
CS / TFT_CSAny GPIO chip-select, e.g. PA4
DC / RSAny GPIO, e.g. PB0
RESET / RSTAny GPIO or MCU reset through suitable circuit, e.g. PB1
LED / BL3.3 V through current control, or GPIO/PWM via transistor if backlight current is high
SD_CSSeparate GPIO chip-select if using SD card
SD_MOSISame SPI MOSI
SD_MISOSame SPI MISO
SD_SCKSame SPI SCK
Important design notes:
  • Use 3.3 V logic with STM32F446. Do not drive the display with 5 V logic unless the module has level shifting.
  • TFT and SD card can share SPI SCK/MOSI/MISO, but they need separate CS pins.
  • Add local decoupling near the display connector: at least 100 nF plus 4.7–10 µF across VCC/GND.
  • If the backlight pin draws more than a few mA, drive it with a MOSFET or BJT instead of directly from an STM32 GPIO.
  • Confirm whether your display module has an onboard 3.3 V regulator and level shifters before tying VCC to 5 V.
To proceed with actual schematic wiring, I’d need edit access to the project and confirmation of the exact STM32F446 part or board you want to use, for example STM32F446RE, STM32F446ZE, or a Nucleo/Discovery board.
