Detailed Description

template<typename channel>
class bmptk::hardware::port_buffer_out< channel >

template for a buffered 8-bit output_only port

This template must be instantiated with a port_buffered_out_channel that implements the access to the chip that has the pins.

Member Function Documentation

template<typename channel>

static void bmptk::hardware::port_buffer_out< channel >::init ( )

inlinestatic

initialize the port as output

This method initializes all pins of the port as output pins. This might involve configuring the pins as gpio, and disabling analog or other special functions.

Definition at line 480 of file ports.h.

template<typename channel>

static void bmptk::hardware::port_buffer_out< channel >::set ( unsigned int  x )

inlinestatic

set the curret level on the pins in the port

This method sets the current level output by each pin that makes up the port, encoded in the bits in parameter value. The value pin of pin N is determined by the Nth bit.When the value is true a logic one (high voltage, Vdd) will appear on the pin, when the value if false a the pin will output a logic zero (low voltage, Vss).The init() method must be called first.
