Difference: BoardSupportPackageH743 (3 vs. 4)

• Forth as CMSIS-RTOS thread. CMSIS-RTOS API to use FreeRTOS from Forth.
• Buffered terminal I/O (5 KiB buffer for UART Rx). Interrupt driven and RTOS aware, key and emit block the calling thread.
  • USART1: D0 RX, D1 TX

• USB-CDC for serial communication via USB. Redirect console I/O like cdc-emit, cdc-key
• microSD and internal Flash mass storage for blocks and FAT filesystem.
  • Internal Flash drive 0:, 1024 KiB

• • Filesystem API
  • UNIX like Shell commands
• LEDs: LED1 (green, PB0), LED2 (yellow, PE1), LED3 (red, PB14)

• Digital and analog pins, Arduino Uno Header
  • Digital port pins: D0 to D15 (ST Zio D16 to D72)
  • Analog port pins: A0 to A5 (ST Zio A6 to A8)
  • PWM:

• • EXTI: D11, D12, D13
• SPI: D2 SCK, D3 MISO, D4 MOSI (e.g. for display, memory)
• I2C: D14 SDA, D15 SCL (external peripherals)

• Alternate uses: USART6_TX

D7 / PC13 / CN10.2

• Alternate uses: SPI6_MISO, USART6_RTS
