Introduction

The STM32-F4 Trainer was developed by the Department of Electrical Engineering at the Nelson Mandela Metropolitan Univeristy to demonstrate the operation of STMicroelectronics' STM32F4-Discovery board (www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF252419).

 

The STM32F4-Discovery itself contains a STM32F407VGT6 microcontroller featuring a 32-bit ARM Cortex-M4F core and an integrated ST-LINK/V2 programmer/debugger.  It also hosts the following on-board functions:

• LIS302DL 3-axis digital accelerometer
• MP45DT02 digital microphone
• CS43L22 audio DAC with speaker driver
• 4 user LEDs (orange, green, red, and blue)
• User pushbutton (blue)
• USB OTG with micro-AB connector

 

The STM32-F4 Trainer is an extension of STM32F4-Discovery board and provides the following additional features and peripherals:

• 8 Red LEDs connected to parallel output pins
• 8 Dip switches connectd to parallel input pins
• Red, green and blue status LEDs
• A single RGB LED
• 5-Way joystick switch
• Graphics LCD with backlight
• 4x4 Keypad
• Potentiometer for analog input
• Graphics LCD with backlight
• DC Motor connected using a H-bridge
• Stepper motor
• Servo motor
• HC-SR04 Range sensor
• USB or RS-232 connection to the STM32F407VGT6's UART
• CAN connector to the STM32F407VGT6's CAN controller
• SDCard connector
• 23LC1023 1Mbit SPI RAM
• 24LC1025 1024K I²C EEPROM
• 2 x MCP23008 8-bit port expanders (connected to the Keypad, Status LEDs and joystick switch)

 

For more information on the usage of the STM32-F4 Trainer or the STM32F4-Discovery board by itself, see the STM32F4-Discovery Board (using Keil and the standard peripheral libraries) and ARMmbed (using the online ARMmbed compiler) pages on this website.
