Function Documentation

◆ console_initialize()

rtems_device_driver console_initialize ( rtems_device_major_number  major,
rtems_device_minor_number  minor,
void *  arg 
)

Serial drivers init function.

Console initialization entry point.

Initialize all serial drivers specified in driver_context_table

Parameters
[in]major
[in]minor
[in]arg
Return values
RTEMS_SUCCESSFULInitialization completed

◆ tms570_sci_set_attributes()

bool tms570_sci_set_attributes ( rtems_termios_device_context base,
const struct termios *  t 
)

Set attributes of the HW peripheral.

Sets attributes of the HW peripheral (parity, baud rate, etc.)

Parameters
[in]basecontext of the driver
[in]ttermios driver
Return values
trueperipheral setting is changed

}
}
#define RTEMS_TERMIOS_DEVICE_CONTEXT_INITIALIZER(name)
Initializer for static initialization of Termios device contexts.
Definition: termiostypes.h:129
Definition: reg_sci.h:44

Table including all serial drivers.

Definitions of all serial drivers

◆ tms570_sci_handler_interrupt

const rtems_termios_device_handler tms570_sci_handler_interrupt
Initial value:

}
bool tms570_sci_set_attributes(rtems_termios_device_context *base, const struct termios *t)
Set attributes of the HW peripheral.
Definition: tms570-sci.c:245
#define NULL
Requests a GPIO pin group configuration.
Definition: bestcomm_api.h:77

Struct containing definitions of interrupt driven driver functions.

Encapsulates interrupt driven driver functions. Use of this table is determited by defining TMS570_USE_INTERRUPTS

◆ tms570_sci_handler_polled

Initial value:
= {
.first_open = tms570_sci_poll_first_open,

.mode = TERMIOS_POLLED
}
bool tms570_sci_set_attributes(rtems_termios_device_context *base, const struct termios *t)
Set attributes of the HW peripheral.
Definition: tms570-sci.c:245

Struct containing definitions of polled driver functions.

Encapsulates polled driver functions. Use of this table is determited by not defining TMS570_USE_INTERRUPTS
