6.3 Interface Functions
6.3.1 Generic
Prototype: void APPL_Application(void)
Parameter Void
Return void
Description This function is called by the synchronization ISR or from the mainloop if not
synchronization is activated.
Prototype: UINT16 APPL_GetDeviceID (void)
Parameter Void
Return Explicit Device ID which is written to the AL Status Code register.
Description This function is called if the master requests the Explicit Device ID.
Only required if the slave supports Explicit Device ID handling
(EXPLICIT_DEVICE_ID).
Prototype: UINT16 (* pAPPL_EEPROM_Read)(UINT32 wordaddr)
Parameter Wordaddr start word address within the EEPROM memory
Return 0 if the operation was successful.
greater 0 an error has occurred
Description This is an optional function and only required if EEPROM_EMULATION is
enabled and no EEPROM content is created (CREATE_EEPROM_CONTENT
== 0)
This function shall copy EEPROM data to the ESC EEPROM data register
(0x508:0x50F/0x50B).
The EEPROM data starting at the specified word address and the length
specified with "EEPROM_READ_SIZE".
The data shall be copied to the ESC EEPROM buffer (ESC offset 0x508)
