STM32F7 is finaly here !

Kilohercas

STMicroelectronics 32F746GDISCOVERY Discovery Kit helps discover STM32F7 Series of microcontrollers based on the ARM Cortex-M7 core. It allows for developing and sharing applications and can support audio/video player audio recorders and home intruder alarms. HMIs can also be designed, taking benefit of audio, video and color touchscreen features.

  • STM32F746NGH6 microcontroller featuring 1Mbytes of Flash memory and 340Kbytes of RAM, in BGA216 package
  • On-board ST-LINK/V2-1 supporting USB reenumeration capability
  • USB functions: virtual COM port, mass storage, debug port
  • 4.3" 480x272 color LCD-TFT with capacitive touchscreen
  • Camera connector
  • SAI audio codec
  • Audio line in and line out jack
  • Stereo speaker outputs
  • Two ST MEMS microphones
  • SPDIF RCA input connector
  • Two pushbuttons (user and reset)
  • 128-Mbit Quad-SPI Flash memory
  • 128-Mbit SDRAM (64 Mbits accessible)
  • Connector for microSD card
  • RF-EEPROM daughterboard connector
  • USB OTG HS with Micro-AB connectors
  • USB OTG FS with Micro-AB connectors
  • Ethernet connector compliant with IEEE-802.3-2002
  • Five power supply options:
    • ST LINK/V2-1
    • USB FS connector
    • USB HS connector
    • VIN from Arduino connector
    • External 5V from connector
  • Power supply output for external applications: 3.3V or 5V
  • Arduino Uno V3 connectors
  • Comprehensive free software including a variety of examples, part of STM32Cube package

 

In order to use this development board, please download latest IAR ARM version, since examples will not be able to compile first time, and may need some work to get it running !


Also, it looks like STM is ditching std libraries for this, and i am very not happy about it. It is completely different approach to get programs working between F1 F2 F4 F7 platforms. So for me at least it will be hard to switch to HAL libraries ( Hardware abstract layer)

  • Also, it looks like STM is ditching std libraries for this, and i am very not happy about it. It is completely different approach to get programs working between F1 F2 F4 F7 platforms. So for me at least it will be hard to switch to HAL libraries ( Hardware abstract layer)

    One of the really grim things about the HAL is that although the names of a great many things have changed the names of some globally used structures have not (although the structure itself is changed) so you can't run the traditional library alongside the HAL image

     

    (This experience is from porting a large project written using Keil tools and ST libraries to latest versions of Keil and St support stuff. Of course the sections of code where I poke the hardware directly using no library functions work just fine. So I guess the lesson is that you pay in the end for that quick fix.

    ST have been moving away from their Standard peripheral libraries for a while. I haven't yet migrated my projects to the Cube HAL libraries, don't quite trust them yet.

     

    Interesting that ST were the first to announce a Cortex M7 part (about 9 months ago!) but it was a long time before the parts were available.

     

    You forgot to mention the price of the F7 discovery board is about US75, up from the F429 discovery board which was US25
