Pin speed manipulation.

Function Documentation

static void pin_speed_fast ( const uint32_t  pin)

static

Set pin speed to fast mode.

As an side effect, maximum current draw from/to the pin will be less limited.

Warning

Should be called after output mode set. Do not call when pin is in input or analog mode.

Parameters

[in]

pin

pin name (pin_name_base)

Definition at line 156 of file pin_v0.h.

References _pin_pinno(), _pin_port(), and _pin_setspd().

static void pin_speed_high ( const uint32_t  pin)

static

Set pin speed to highest mode.

As an side effect, maximum current draw from/to the pin will not be limited, allowing external device may destroy the pin during collision.

Warning

Should be called after output mode set. Do not call when pin is in input or analog mode.

Note

when architecture doesn't support this mode, the meaning should be same as pin_speed_fast function

Parameters

[in]

pin

pin name (pin_name_base)

Definition at line 161 of file pin_v0.h.

References _pin_pinno(), _pin_port(), and _pin_setspd().

static void pin_speed_low ( const uint32_t  pin)

static

Set pin speed to slowest mode.

As an side effect, maximum current draw from/to the pin will be very limited.

Warning

Should be called after output mode set. Do not call when pin is in input or analog mode.

Parameters

[in]

pin

pin name (pin_name_base)

Definition at line 146 of file pin_v0.h.

References _pin_pinno(), _pin_port(), and _pin_setspd().

static void pin_speed_medium ( const uint32_t  pin)

static

Set pin speed to medium speed mode.

As an side effect, maximum current draw from/to the pin will be limited.

Warning

Should be called after output mode set. Do not call when pin is in input or analog mode.

Parameters

[in]

pin

pin name (pin_name_base)

Definition at line 151 of file pin_v0.h.
