files to modify

  • add eeprom address to eeprom_memmap.h
    • could be else where, but helps us to keep track of what is being used where
  • add macros to pyshared.c that list the global ram address, and or EEPROM address and virtual variable name
  • to global.c, declare the global
  • to global.h, define the global typedef
    • latter two (global) files are optional, but help keep everything in one place

example

eeprom_memmap.h

#define PERSISTENT_DATA_C1_EEPROM_BASE_ADDRESS 0x1500
#define PERSISTENT_DATA_C2_EEPROM_BASE_ADDRESS 0x1580

pyshared.c

...
const SHARED_OBJECT_T SHARED_OBJECT[] = {
...
  SHARED_RAM_OBJ_M(PERSISTENT_DATA_T, persistent_data_c1),                 // use commas at EOL
  SHARED_RAM_OBJ_M(PERSISTENT_DATA_T, persistent_data_c2),
  SHARED_EE_OBJ_M (PERSISTENT_DATA_T, EE_persistent_data_c1, PERSISTENT_DATA_C1_EEPROM_BASE_ADDRESS),
  SHARED_EE_OBJ_M (PERSISTENT_DATA_T, EE_persistent_data_c2, PERSISTENT_DATA_C2_EEPROM_BASE_ADDRESS),
...
} ;

global.h

typedef struct {
  UINT32_T crc;          // this is the standard header, use CRC8 for now.
  UINT16_T version;      
  UINT16_T length;        
  UINT32_T magic;        // "hash" for this typedef from the file pygen_shared_object_hash_codes.h
  //////////////////
  UINT32_T count;
} PERSISTENT_DATA_T;

extern PERSISTENT_DATA_T persistent_data_c1; 
extern PERSISTENT_DATA_T persistent_data_c2;

global.c

PERSISTENT_DATA_T persistent_data_c1; 
PERSISTENT_DATA_T persistent_data_c2; 

void init_global(void) {
 ...
 ZERO_OBJ(persistent_data_c1);
 ZERO_OBJ(persistent_data_c2);
 ...
}
