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
D4pin to the IHM01A1’sD9pin; - to initialize the pwm PinName variable with
D4rather thanD9.
- to connect with a wire from the LPCX’s
- FRDM-K64F board has been tested with the following patch:
- to connect with a wire from the FRDM’s
D4pin to the IHM01A1’sD8pin; - to initialize the standby_reset PinName variable with
D4rather thanD8.
- to connect with a wire from the FRDM’s
Example Applications
- HelloWorld_IHM01A1
- HelloWorld_IHM01A1_2Motors
- MotorControl_IHM01A1
- MemsMotorControl
- MemsMotorControl_IHM01A1_IKS01A2
