  11. This microcontroller is part of the STM32F4 Hi-performance and DSP series of Cortex-M4s from ST.

Board Features

ST-LINK

The ST-LINK is an ST Microelectronics USB JTAG tool for programming and debugging STM8 and STM32 microcontrollers. It is an external tool that is used to program and debug STM microcontrollers using JTAG or SWD (Serial Wire Debug).

An embedded ST-LINK is included on the STM32F4-Discovery evaluation board that can be used to program the onboard STM32F407VG microcontroller. The embedded ST-LINK can also be used to single-step through the source code and debug the target microcontroller.

By removing two jumper links on the board, the embedded ST-LINK can be used as a programmer/debugger to program/debug an ST microcontroller on another board via a cable from the SWD connector. The embedded ST-LINK is limited to programming STM32F microcontrollers via an SWD link only. JTAG is not supported by the embedded ST-LINK.

Peripherals and Headers:

I/O Interface Devices

The board features four user programmable LEDs and a user programmable push-button switch. A second push-button is connected to the reset pin (NRST) of the microcontroller.

Audio

The STM32F407VG is also interfaced to an Audio DAC and MEMS microphone. A stereo audio jack is on board for connecting headphones or speakers to the audio output of the DAC.

USB

The board has one USB OTG full speed port available on a USB micro-B connector.

Motion Sensor

A three-axis linear accelerometer is interfaced to the board.

Headers

All of the I/O pins of the STM32F407VG are available on pin headers. Two 25 by 2 (50 pin) headers are located on either side of the board along its length, one per side. The pin names are silk-screened next to the pin headers. The pin headers protrude from the top of the board allowing easy attachment of oscilloscope or logic analyzer test probes.

Oscillators:

Although the STM32F407VG has two internal RC oscillators, an 8MHz crystal is used for the main oscillator. There is place on the board for a 32.768kHz crystal which is not fitted.

Solder Bridges:

The board has a number of solder-bridge connectors that can be soldered closed or de-soldered to open them in order to make or break connections.

Current Consumption

A jumper link on the board can be removed allowing an ammeter to be connected if current consumption of the microcontroller needs to be measured.

Conclusion

The STM32F4-Discovery evaluation board is an excellent board for learning and evaluating the STM32F4 range of Cortex-M4 microcontrollers from STMicroelectronics. With many onboard peripherals already interfaced to the microcontroller, it provides an opportunity to write some interesting code without the need to add extra external hardware. If the external hardware does need to be interfaced, it can be connected to the two 50 pin headers on the board.
