USB-C Sink 4 click

USB-C Sink 4 Click is a compact add-on board designed to enable devices to draw power through the USB Type-C interface. This board features the CYPD3178, a USB Type-C power sink controller from Infineon. This Click boardâ„¢ includes a controller with an integrated USB Type-C transceiver, load switch control with soft start, and system-level fault protection. It has configurable charging protocols, voltage negotiation, and an unpopulated SAFE 5V header for an alternate power supply.

Software Support

We provide a library for the USB-C Sink 4 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for USB-C Sink 4 Click driver.

Example Description

This example demonstrates the use of a USB-C Sink 4 Click board by setting DC power requests and control for Type-C connector-equipped devices (TCD).

The demo application is composed of two sections :

Application Init

The initialization of the I2C module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
usbcsink4_cfg_t usbcsink4_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
usbcsink4_cfg_setup( &usbcsink4_cfg );
USBCSINK4_MAP_MIKROBUS( usbcsink4_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == usbcsink4_init( &usbcsink4, &usbcsink4_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( USBCSINK4_ERROR == usbcsink4_default_cfg ( &usbcsink4 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, " ------------------------\r\n" );
Delay_ms ( 100 );
}

Application Task

The demo app displays the reports of the Type-C port, active legacy charging mode status, and live voltage measurements on the VBUS supply for the specified port.

void application_task ( void )
{
usbcsink4_display_type_c_status( );
Delay_ms ( 100 );
usbcsink4_display_chrg_mode( );
Delay_ms ( 100 );
usbcsink4_display_bus_voltage( );
Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.USBCSink4

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
