This header file includes the correct processor-specific include file. It also provides additional processor-specific information, such as the device ID, revision IDs, and the number of various peripherals.
Definition in file pic24_chip.h.
| #define DEV_ID 0x00080a |
The device ID for this chip, located in program memory at DEV_ID_LOCATION.
Definition at line 163 of file pic24_chip.h.
Referenced by checkDeviceAndRevision().
| #define DEV_ID_LOCATION 0xFF0000 |
The location in program memory of the device ID. Revision information is found in the Silicon Errata sheet for the device. The Device ID is contained in the datasheet for the target device.

| #define DEV_ID_STR "PIC24HJ12GP201" |
A string to identify this chip, printed by checkDeviceAndRevision().

Referenced by checkDeviceAndRevision().
| #define EXPECTED_REVISION1 0x003001 |
A revision for this device, located in program memory at REVISION_LOCATION. Additional revisions can be defined as EXPECTED_REVISIONn, where n = 1..5.

| #define EXPECTED_REVISION1_STR "A2" |
A string to accompany this revision, printed by checkDeviceAndRevision(). Additional revision strings can be defined as EXPECTED_REVISIONn, where n = 1..5.

| #define NUM_ECAN_MODS 1 |
Define the number of ECAN modules supported by this chip. See NUM_UART_MODS for details on this methodology.
Definition at line 135 of file pic24_chip.h.
| #define NUM_I2C_MODS 1 |
Define the number of I2C modules supported by this chip. See NUM_UART_MODS for details on this methodology.
Definition at line 113 of file pic24_chip.h.
| #define NUM_SPI_MODS 1 |
Define the number of SPI modules supported by this chip. See NUM_UART_MODS for details on this methodology.
Definition at line 124 of file pic24_chip.h.
| #define NUM_UART_MODS 1 |
Define the number of UART modules supported by this chip. NOTE: this only works when testing #defines, not testing variable. So, don't test UxSTA; instead, test _UxRXIF which is uniquely defined for each UART. (Idea taken from the C30 peripheral library, in uart.h.)
Definition at line 102 of file pic24_chip.h.
| #define REVISION_LOCATION 0xFF0002 |
The location in program memory of the revision.
