2.29. Hauppauge TV EEPROM functions and data structures¶
-
enum tveeprom_audio_processor¶
Specifies the type of audio processor used on a Hauppauge device.
Constants
TVEEPROM_AUDPROC_NONENo audio processor present
TVEEPROM_AUDPROC_INTERNALThe audio processor is internal to the video processor
TVEEPROM_AUDPROC_MSPThe audio processor is a MSPXXXX device
TVEEPROM_AUDPROC_OTHERThe audio processor is another device
-
struct tveeprom¶
Contains the fields parsed from Hauppauge eeproms
Definition:
struct tveeprom {
u32 has_radio;
u32 has_ir;
u32 has_MAC_address;
u32 tuner_type;
u32 tuner_formats;
u32 tuner_hauppauge_model;
u32 tuner2_type;
u32 tuner2_formats;
u32 tuner2_hauppauge_model;
u32 audio_processor;
u32 decoder_processor;
u32 model;
u32 revision;
u32 serial_number;
char rev_str[5];
u8 MAC_address[ETH_ALEN];
};
Members
has_radio1 if the device has radio; 0 otherwise.
has_irIf has_ir == 0, then it is unknown what the IR capabilities are. Otherwise: bit 0) 1 (= IR capabilities are known); bit 1) IR receiver present; bit 2) IR transmitter (blaster) present.
has_MAC_address0: no MAC, 1: MAC present, 2: unknown.
tuner_typetype of the tuner (TUNER_*, as defined at include/media/tuner.h).
tuner_formatsSupported analog TV standards (V4L2_STD_*).
tuner_hauppauge_modelHauppauge’s code for the device model number.
tuner2_typetype of the second tuner (TUNER_*, as defined at include/media/tuner.h).
tuner2_formatsTuner 2 supported analog TV standards (V4L2_STD_*).
tuner2_hauppauge_modeltuner 2 Hauppauge’s code for the device model number.
audio_processoranalog audio decoder, as defined by
enum tveeprom_audio_processor.decoder_processorHauppauge’s code for the decoder chipset. Unused by the drivers, as they probe the decoder based on the PCI or USB ID.
modelHauppauge’s model number
revisionCard revision number
serial_numberCard’s serial number
rev_strCard revision converted to number
MAC_addressMAC address for the network interface
-
void tveeprom_hauppauge_analog(struct tveeprom *tvee, unsigned char *eeprom_data)¶
Fill
struct tveepromusing the contents of the eeprom previously filled at eeprom_data field.
Parameters
struct tveeprom *tveeStruct to where the eeprom parsed data will be filled;
unsigned char *eeprom_dataArray with the contents of the eeprom_data. It should contain 256 bytes filled with the contents of the eeprom read from the Hauppauge device.
-
int tveeprom_read(struct i2c_client *c, unsigned char *eedata, int len)¶
Reads the contents of the eeprom found at the Hauppauge devices.
Parameters
struct i2c_client *cI2C client struct
unsigned char *eedataArray where the eeprom content will be stored.
int lenSize of eedata array. If the eeprom content will be latter be parsed by
tveeprom_hauppauge_analog(), len should be, at least, 256.
