Detailed Description

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

template for a buffered 8-bit input port

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

template<typename channel >

static unsigned int bmptk::hardware::port_buffer_in< channel >::get ( )

inlinestatic

get the current values of the pins in the port

This method returns the current level on the pins that make up the port, encoded in the bits in the returned value. The value pin of pin N is returned in the Nth bit.When the level is a logic one (high voltage, Vdd) the bit in the returned value is 1, otherwise (logic zero, low level, Vss) the bit is 0.The init() method must be called first. Note that after setting a pin low(0) the pin will in all probability read as 0, so this call only makes realy sense for pins set high (1) call.

template<typename channel >

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

inlinestatic

initialize the port as input

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