Macro Definition Documentation

◆ VSF_USART_CFG_MULTI_CLASS

#define VSF_USART_CFG_MULTI_CLASS ENABLED

◆ VSF_USART_CFG_PREFIX

#define VSF_USART_CFG_PREFIX vsf

In the application code, we can redefine this macro to call the actual API directly without a runtime cost. For example: #define VSF_USART_CFG_MULTI_CLASS vsf_hw vsf_usart_init(&vsf_hw_usart0, &cfg); It will be expanded at compile time to vsf_hw_usart_init(&vsf_hw_usart0, &cfg).

Dependency: VSF_USART_CFG_FUNCTION_RENAME enable

◆ VSF_USART_CFG_FUNCTION_RENAME

#define VSF_USART_CFG_FUNCTION_RENAME ENABLED

If VSF_USART_CFG_FUNCTION_RENAME is enabled, the actual API is called based on the value of VSF_USART_CFG_PREFIX

◆ VSF_USART_CFG_REIMPLEMENT_TYPE_MODE

#define VSF_USART_CFG_REIMPLEMENT_TYPE_MODE DISABLED

In the specific hardware driver, we can enable VSF_USART_CFG_REIMPLEMENT_TYPE_MODE to redefine vsf_usart_mode_t as needed.

◆ VSF_USART_CFG_REIMPLEMENT_TYPE_IRQ_MASK

#define VSF_USART_CFG_REIMPLEMENT_TYPE_IRQ_MASK DISABLED

In the specific hardware driver, we can enable VSF_USART_CFG_REIMPLEMENT_TYPE_IRQ_MASK to redefine vsf_usart_irq_mask_t as needed.

◆ VSF_USART_CFG_REIMPLEMENT_TYPE_STATUS

#define VSF_USART_CFG_REIMPLEMENT_TYPE_STATUS DISABLED

In the specific hardware driver, we can enable VSF_USART_CFG_REIMPLEMENT_TYPE_STATUS to redefine vsf_usart_status_t as needed.

◆ VSF_USART_CFG_REIMPLEMENT_TYPE_CMD

#define VSF_USART_CFG_REIMPLEMENT_TYPE_CMD DISABLED

In the specific hardware driver, we can enable VSF_USART_CFG_REIMPLEMENT_TYPE_CMD to redefine vsf_usart_cmd_t as needed.

#define VSF_USART_CFG_REIMPLEMENT_MODE_TO_DATA_BITS DISABLED

◆ VSF_USART_CFG_REIMPLEMENT_TYPE_CFG

#define VSF_USART_CFG_REIMPLEMENT_TYPE_CFG DISABLED

Redefine struct vsf_usart_cfg_t. The vsf_usart_isr_handler_t type also needs to be redefined For compatibility, members should not be deleted when struct vsf_usart_cfg_t redefining.

◆ VSF_USART_CFG_REIMPLEMENT_TYPE_CAPABILITY

#define VSF_USART_CFG_REIMPLEMENT_TYPE_CAPABILITY DISABLED

Redefine struct vsf_usart_capability_t. For compatibility, members should not be deleted when struct vsf_usart_capability_t redefining.

Typedef Documentation

◆ vsf_usart_mode_t

typedef enum vsf_usart_mode_t vsf_usart_mode_t

Predefined VSF USART modes that can be reimplemented in specific hal drivers.

Even if the hardware doesn't support these modes, the following modes must be kept， If the hardware supports more modes, e.g. more parity modes, more databits, more stopbits, more FIFO threshold size, we can implement it in the hardware driver:

If more new modes are added to the driver, then the corresponding MASK macros need to be defined to include the values of the new modes. For example, Adding the new TX FIFO Threshold option requires that the macro VSF_USART_TX_FIFO_THRESH_MASK be defined. Adding the new parity check option requires the macro VSF_USART_PARITY_MASK be defined. Adding the new stop bit option requires the macro of VSF_USART_BIT_LENGTH_MASK be defined.

Optional features require one or more enumeration options and a macro with the same name to determine if they are supported at runtime. If the feature supports more than one option, it is recommended to provide the corresponding MASK option, so that the user can switch to different modes at compile-time.

◆ vsf_usart_irq_mask_t
