2.1.1

User Interfaces

The main interfaces used to communicate with the SDK-ST10F276 platform include:

●

Two CAN 2.0B interfaces which operate on one or two CAN buses (30 or 2x15

message objects)

●

One RS232 connector for serial signal communication with external devices

●

One I2C connector for additional external device management

●

Three dedicated connectors for motion control (external power motor boards)

●

A series of general purpose LEDs and DIP switches

●

One potentiometer and a push-button

For the user's convenience, the ST10 I/O pins on the Development board are split into four

main connectors located on each side of the ST10 device

The five general purpose Light Emitting Diodes (LEDs) may be used for end-user

applications.

They can be activated via the JP2 connector, or by using a series of dip switches on the

board.

The potentiometer and push-button may be set in different and independent ways for

general purpose uses.

2.1.2

On board motor control connectors

The SDK-ST10F276 board provides an embedded solution (3 modular connectors) for

power requirements up to 3000W, so they are well-suited for driving motors (e.g. BLDC,

Brushless Direct Current) via an appropriate external motor board. The various power

boards that can be connected to the SDK-ST10F276 are optimized in order to support a

wide variety of advanced motor control applications.

Each of the three power connectors on the SDK-ST10F276 development board has 26 pins

(see Figure 9). When a connector is used with a compatible motor board, the user can drive

motors with the following signals:

●

PWM

●

Hall Effect sensor/GPIO

●

Power/Brake

●

Encoder

●

Tachometer/Resolver

●

Shutdown, and Alarm
