Interface Functions

ITM Interface Functions

void interface_io_Init ( void * pobj )

Initialize ITM interface.

Parameters :

pobj – Reserved, pass NULL.

uint32_t interface_io_Send ( const uint8_t * Ptr , uint16_t Size )

Send a buffer over ITM stimulus port.

Parameters :

• Ptr – Pointer to data buffer.

• Size – Number of bytes to transfer.

Returns :

Bytes written.

USART Interface Functions

static hal_uart_handle_t * itf_huart = NULL

void interface_io_Init ( void * pobj )

Initialize UART interface.
