#USE FIXED_IO (port_outputs=pin, pin?)
port is A-G, pin is one of the pin constants defined in the devices .h file.
This directive affects how the compiler will generate code for input and output
instructions that follow. This directive takes effect until another #USE XXX_IO directive
is encountered. The fixed method of doing I/O will cause the compiler to generate code
to make an I/O pin either input or output every time it is used. The pins are programmed
according to the information in this directive (not the operations actually
performed). This saves a byte of RAM used in standard I/O. When linking multiple
compilation units be aware this directive only applies to the current compilation unit.
#use fixed_io(a_outputs=PIN_A2, PIN_A3)
None
#USE FAST_IO, #USE STANDARD_IO, General Purpose I/O
#use i2c
Syntax:
Elements:
#USE I2C (options)
Options are separated by commas and may be:
MASTER Sets to the master mode
MULTI_MASTER Set the multi_master mode
SLAVE
Set the slave mode
SCL=pin
Specifies the SCL pin (pin is a bit address)
SDA=pin
Specifies the SDA pin
ADDRESS=nn Specifies the slave mode address
FAST
Use the fast I2C specification.
FAST=nnnnnn Sets the speed to nnnnnn hz
