Overview

Support of STM32F429I-DISCO and DISC1 boards

Two different board references are available: STM32F429I-DISCO and STM32F429I-DISC1.

The discovery board referenced STM32F429I-DISCO does not support the drag&drop and Virtual Comm Port features. If you are using this board version, you will have to use an external tool (for example the STM32 STLink utility) to program your code .bin file. There is no possibility to use either the printf in your code.

The board referenced STM32F429I-DISC1 does not have these limitations.

This discovery board offers everything required for users to get started quickly and develop applications easily. The full range of hardware features on the board helps to evaluate almost all peripherals and develop your own applications.

The STM32F429I-DISC1 board includes an ST-LINK/V2-B embedded debug tool, a 2.4" QVGA TFT LCD, an external 64-Mbit SDRAM, an ST MEMS gyroscope, a USB OTG micro-AB connector, LEDs and push-buttons.
