46 cdl_package CYGPKG_IO_I2C {
48 requires CYGPKG_INFRA CYGPKG_HAL
54 The generic I2C package provides an API for accessing devices
55 attached to an I2C bus. It specifies how I2C bus drivers should
56 be written and how I2C devices should be defined. There is also
57 support for bit-banged I2C buses."
59 cdl_option CYGNUM_I2C_INIT_PRIORITY {
60 display "I2C initialization priority"
62 default_value { "CYG_INIT_DRIVERS" }
65 The generic I2C package will initialize each I2C bus during
66 system startup, using a prioritized static constructor. This
67 option controls the priority that is used. The default value,
68 CYG_INIT_DRIVERS, means that I2C buses get initialized early
72 cdl_component CYGPKG_IO_I2C_OPTIONS {
73 display "I2C build options"
76 Package specific build options including control over
77 compiler flags used only in building the generic I2C
78 package, and details of which tests are built."
80 cdl_option CYGPKG_IO_I2C_CFLAGS_ADD {
81 display "Additional compiler flags"
86 This option modifies the set of compiler flags for
87 building the generic I2C package. These flags are
88 used in addition to the set of global flags."
91 cdl_option CYGPKG_IO_I2C_CFLAGS_REMOVE {
92 display "Suppressed compiler flags"
97 This option modifies the set of compiler flags for
98 building the generic I2C package. These flags are
99 removed from the set of global flags if present."
