Function Documentation

U32BIT APP_NvmGetDvbSize

(

void

)

Returns the size in bytes the DVB module uses to save its settings.

Returns

size of DVB settings in bytes

U32BIT APP_NvmRead

(

E_NVM_ITEMS

nvm_item

)

Returns the current value for the given DVB setting.

Parameters

nvm_item

- value to be read

Returns

current value

U32BIT APP_NvmReadDefault

(

E_NVM_ITEMS

nvm_item

)

Returns the factory default value for the given DVB setting.

Parameters

nvm_item

- value to be read

Returns

factory default value

U8BIT* APP_NvmReadString

(

E_NVM_ITEMS

nvm_item

)

Returns pointer to current string for the given DVB setting.

Parameters

nvm_item

- value to be read

Returns

pointer to string

void APP_NvmSave	(	E_NVM_ITEMS	nvm_item,
		U32BIT	new_value,
		BOOLEAN	write_to_flash_now
	)

Sets the current value for the given DVB setting.

Parameters

nvm_item	- item to be read
new_value	- value for the item
write_to_flash_now	- if TRUE then all the current values will be saved. When changing the values of several items, it will be more efficient to only this this TRUE for the last item

void APP_NvmSaveString	(	E_NVM_ITEMS	nvm_item,
		U8BIT *	str_ptr,
		BOOLEAN	write_to_flash_now
	)

Sets the current value for the given DVB setting.

Parameters

nvm_item	- item to be written
str_ptr	- pointer to string for the item
write_to_flash_now	- if TRUE then all the current values will be saved. When changing the values of several items, it will be more efficient to only this this TRUE for the last item
