Functions
bool	initCnfs (void)
	Initialize the CNFS file system. This is used to store assets like WSGs and fonts.

bool	deinitCnfs (void)
	De-initialize the CNFS file system (right now a noop)

const uint8_t *	cnfsGetFile (const char fname, size_t flen)
	Get a pointer to a file, without needing to read it. Same rules that apply to cnfsGetFile, and under the hood, cnfsGetFile uses this function.

uint8_t *	cnfsReadFile (const char fname, size_t outsize, bool readToSpiRam)
	Read a file from CNFS into an output array. Files that are in the assets_image folder before compilation and flashing will automatically be included in the firmware.

Function Documentation

◆ initCnfs()

bool initCnfs ( void )

Initialize the CNFS file system. This is used to store assets like WSGs and fonts.

Returns: true if CNFS was initialized and can be used, false if it failed

◆ deinitCnfs()

bool deinitCnfs ( void )

De-initialize the CNFS file system (right now a noop)

Returns: true if de-initialize ok, false if it was not

◆ cnfsGetFile()

const uint8_t * cnfsGetFile	(	const char *	fname,
		size_t *	flen )

Get a pointer to a file, without needing to read it. Same rules that apply to cnfsGetFile, and under the hood, cnfsGetFile uses this function.

Parameters

fname	The name of the file to find.
flen	A pointer to a size_t to return the size of the file.

Returns: A pointer to the read data if successful, or NULL if there is a failure Do not free this pointer. It is pointing to flash.

◆ cnfsReadFile()

uint8_t * cnfsReadFile	(	const char *	fname,
		size_t *	outsize,
		bool	readToSpiRam )

Read a file from CNFS into an output array. Files that are in the assets_image folder before compilation and flashing will automatically be included in the firmware.
