1.8 Interfaces
1.8.1 RS232
The STM32F100VB evaluation board (STM32100B-EVAL) provides two on-board RS-232
serial ports. Both RS232 ports are accessed via DB9 connectors.
1.9 Motor
control
The STM32100B-EVAL evaluation board supports inductor motor control via a 34-pin
connector. This connector provides all required control and feedback signals to and from the
motor power-driving board.
1.10 IrDA
The STM32100B-EVAL evaluation board supports IrDA communication. The interface is
mounted on USART3.
1.11 Miscellaneous
peripherals
1.11.1 Joystick
The board features a four-direction joystick with a selection key.
1.11.2 Push-buttons
The following push-buttons are available:
●
Key
●
Tamper
●
Wakeup: used to wake up the processor from low power mode
1.11.3 12-bit
analog-to-digital converter (ADC)
The MCU ADC channel (
ADC1_IN14
) is connected to an on-board variable resistor. The
variable resistor provides a voltage in the range of 0 V to 3.3 V.
Moreover, a BNC connector is available for analog input.
1.11.4 Audio
amplifier
The STM32100B-EVAL evaluation board implements a dedicated audio amplifier which can
be interfaced with the STM32 DAC peripheral. For the audio output, a speaker and an audio
jack connector are available on the board and connected to the DAC.
1.11.5 Storage
memories
The STM32100B-EVAL evaluation board features an 8 Mbyte SPI Flash memory and an SD
Card™ memory connected to the SPI1 peripheral.
