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)
