 Hello, and welcome to this STM32-F769 Discovery Kit Getting Started video. The STM32-F7 series is part of the performance range of the STM32 microcontroller family, featuring a large set of communication peripherals, making it the best fit for a wide range of applications, such as multimedia, Internet of Things, home automation, industrial, and medical. Through the operation of the pre-programmed demonstration firmware, we will demonstrate the performance capability of the STM32-F7 series, as well as its large peripheral set. The STM32-F769-based Discovery Kit is designed to be the quickest way to evaluate the STM32-F7 series and to discover its features, such as connectivity and processing performance in real applications. The STM32-F769-NIH6 microcontroller embeds 2 megabytes of flash memory and 512 kilobytes of RAM. It is available in a TFBGA216 package. Code or data size are not limited thanks to external memories like SD-RAM, SRAM, and flash memory, which are supported via the FMC, QuadSPI, or SDIO interfaces. Audio is supported thanks to the SAI, I2S, or SPDIF interfaces. The STM32-F769-779 lines offer the performance of the Cortex-M7 core, with a double precision floating point unit running up to 216 MHz. They offer similar lower static power consumption as the STM32-F427-437 and STM32-F429-439 lines. Now, let's take a look at the main components and features of the STM32-F769 Discovery Board. On the front face, we can see the 4-inch WVGA MIPI DSI display with capacitive touchscreen, 4 MEMS microphones, push buttons, Wi-Fi module connector, and 5-volt power supply output, accessories that enhance flexibility and extend application reach, including the BLC-DAD RPI-1 15-pin single-row flexible printed circuit DSI adapter board, and BLC-DAD HDMI-1 DSI-2 HDMI adapter, which enhance flexibility to attach a wide variety of displays are available. Flip over the board and look at the bottom side. At first glance, we can see the specificity of this board that provides numerous connectors, which are useful for evaluating the device's performance in connected applications. Here is a brief description of the main components of the board. To facilitate the development of applications based on the STM32-F7 Discovery Board, an on-board ST-Link V2-1 debug and programming tool is embedded in the discovery. On this side, you can see the STM32-F769 microcontroller based on the ARM Cortex-M7 core in a TFBGA-216 package with a microSD card reader, analog and digital audio connectors, Arduino headers, 128 megabit SD RAM, USB on-the-go, RJ45 connector, and associated Power Over Ethernet circuitry. The STM32-F777 and STM32-F779 variants come with extra cryptographic features on chip, such as an efficient hardware engine offering several security algorithms. To operate the board and access the functions of the pre-programmed application, power the board using the USB ST-Link connector. First of all, check the system information. The embedded firmware of the Discovery is part of the STM32-Cube-F7, which is open software that can be reused. Verify if your Discovery's firmware release is up to date. To do this, compare the release number displayed on the screen with the one inside the STM32-Cube-F7 package, directly available from the 32F769i Discovery product page at www.st.com slash stm32f7-discovery. Now back to the main menu. We will enter the audio player application. This application can play audio files from microSD cards and USB keys. The STM32-F7 MCU has two dedicated audio PLLs, three half-duplex I2S interfaces, a new serial audio interface supporting time division multiplex mode, and a digital filter for a Sigma Delta modulator or DF-SDM module. The STM32-F7 Discovery kit also includes a video player application. You can play video files from microSD cards and USB keys. Thanks to the audio recorder application, you can capture sounds using the embedded microphones. A VNC server lets you remotely control the STM32-F769 kit from a computer using a VNC client. The home alarm application controls the cameras inside a house. Different zones can be activated and monitored independently. No camera is mounted on the 32F769i Discovery board. Pictures are stored in flash memory and are used instead of camera streaming. TouchGFX is a software framework that enables high-end GUIs on embedded systems. The TouchGFX technology optimizes the utilization of small hardware platforms, resulting in faster image updates with less MCU load. Embedded wizard is TARA systems' embedded GUI technology that enables you to create platform independent and high-performance graphical user interfaces or GUIs even on resource constrained microcontrollers. Back to the TouchGFX demo, you can appreciate the fluidity of the user interface and look at a wide range of application examples. The embedded wizard demo also has a high responsiveness and can be used in many application fields. Playing the bird eat coin game, you can appreciate the efficiency of the CromArt accelerator. Using this feature, the MCU load is only around 3%. It climbs to more than 70% without it. The JPEG codec increases video player performance from 8 to 20 frames per second. Let's take a look at two graphical user interfaces or GUIs developed using embedded wizard. The first GUI simulates a smart washing machine interface. The second GUI simulates a smart thermostat. Using the DSi to HDMI adapter, you can display discovery board outputs to an HDMI monitor. A specific firmware is required because the touch screen is no longer available to control applications. You can wirelessly upgrade the Discovery Kit firmware using the ESP01 Wi-Fi module available from electronics distributors. The firmware binary is hosted on an Android phone acting as an access point and web server. Demo firmware is able to connect to the mobile phone, download a new firmware, program it to flash memory, and finally reboot to the new firmware. As you can see, the Discovery Kit has obtained an IP address from the Wi-Fi access point. Then hello.bin firmware is downloaded from the HTTP server and programmed into flash memory. The application board is now running the new firmware. More information is available at st.com. STM32F769 Discovery Kits can be ordered online.
