Motor Control Library

Introduction

Library to handle the X-NUCLEO-IHM01A1 Motor Control Expansion Board based on the the L6474 component.

Daisy-Chain Configuration

This board can be stacked up to three times so that the L6474 components will be connected in daisy-chain configuration. For this purpose, some resistors must be correctly connected on the boards as depicted here below:

Platform compatibility

• NUCLEO boards have been tested with the default configuration provided by the HelloWorld_IHM01A1 example.

• LPCXpresso11U68 board has been tested with the following patch:
  • to connect with a wire from the LPCX’s D4 pin to the IHM01A1’s D9 pin;
  • to initialize the pwm PinName variable with D4 rather than D9.

• FRDM-K64F board has been tested with the following patch:
  • to connect with a wire from the FRDM’s D4 pin to the IHM01A1’s D8 pin;
  • to initialize the standby_reset PinName variable with D4 rather than D8.

Example Applications

• HelloWorld_IHM01A1
• HelloWorld_IHM01A1_2Motors
• MotorControl_IHM01A1
• MemsMotorControl
• MemsMotorControl_IHM01A1_IKS01A2
