IoT Device Prototyping with STMicroelectronics Nucleo Development Boards – Day 5

STMicroelectronics provides a set of functions packaged as a BSP (Board Support Package) that is designed to support the X-NUCLEO-GFX01M1 Display Expansion. If you browse the functions contained within the BSP you will note that all of the BSP functions reference the ILI9341 TFT driver SOC. If your application requires the storage and retrieval of pretty pictures the X-NUCLEO-GFX01M1 comes loaded with an MX25L6433Fa 64-Mbit SPI NOR Flash device that is also supported by the BSP. The X-NUCLEO-GFX01M1 interfaces to the NUCLEO-G071RB's on-board STM32G071RB microcontroller via the NUCLEO-G071RB's MORPHO headers. Since the X-NUCLEO-GFX01M1's display is not touch-enabled interaction between the user the display and the application can be enabled by coding in the GPIO pins that are attached to the X-NUCLEO-GFX01M1's on-board joystick. The goal of today's lecture is to gain an understanding of how the X-NUCLEO-GFX01M1 BSP functions work and apply our new-found knowledge in the form of a joystick-enabled wireless remote control IoT application.
