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.
