Detailed Description

HBridge3 Click example.

Description

H-bridge in general, allows the current to flow in one or another direction. This click is used for driving a H-Bridge motor by changing output states. The outputs can be pulse width modulated at frequencies up to 20kHz by means of PWM/DIR control.

The demo application is composed of two sections :

Application Init

Initializes SPI and LOG modules, AN, RST, CS and PWM pins

Application Task

This example demonstrates the use of H-Bridge 3 Click board, by running dc motor in both directions - increasing and decreasing PWM duty cycle. Results are being sent to the Usart Terminal where you can track their changes.

Note

If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
