The address space is split into smaller chunks, grouped by common functionality: | The following tables provide information on how to access the camera's functionality for ''FX3 Host Vendor Command Interface''. The address space is split into smaller chunks, grouped by common functionality: |
| | |
| | ===== 0x00-0x9F ===== |
| | ^Name ^Offset ^wIndex ^wValue ^Access type ^Byte length ^Return buffer bits ^Notes ^ |
| | |Reserved|''0x00''-''0x9F''| | | | | |Think of this as "system address space"| |
| | |
| | |
| | ===== 0xA0-0xA7 ===== |
| | ^Name ^Offset ^wIndex ^wValue ^Access type ^Byte length ^Return buffer bits ^Notes ^ |
| | |Bootloader check|''0xA0''| | |R/W| | |Check if a bootloader is running, the result is in the command's status code (success/failure interpreted as ''true''/''false'')| |
| | |Reserved|''0xA1''| | | | | | | |
| | |Run DPC calibration|''0xA2''| |DPC Threshold|W/O| | |Start the dynamic DPC calibration with the given DPC Threshold in range [0..255]| |
| | |Reconfig FGPA|''0xA3''| | |W/O| | |Writing anything into this register causes the FPGA to reconfigure itself from SPI Flash| |
| | |FPGA I²C Bridge|''0xA4''|FPGA register offset|FPGA data (write)|R/W|''0'' or ''1''|''7:0'' - FPGA data|FPGA write returns 0 byte buffer, FPGA read returns 1 byte buffer. Read/write is requested via control endpoint's direction attribute being set to ''DIR_FROM_DEVICE''/''DIR_TO_DEVICE''.\\ For details on individual commands refer to [[#FPGA I²C bridge|FPGA I²C bridge]]| |
| | |Sensor I²C bridge (8-bit configuration registers)|''0xA5''| Sensor register | ''mask'' and ''data'' (if writing) - see Notes column for details |R/W|''0'' or ''1''| ''7:0'' - sensor register's data | ''mask'' - an 8-bit MSB that specifies which bits to affect during a write operation - only the bits that are set in ''mask'' will be affected by bits in ''data''. Setting ''mask'' to ''0'' ultimately turns a write operation into a read one as no bits are getting modified\\ ''data'' - an 8-bit LSB that specifies the new data to write into sensor's register. The write only affects the bits that are set in ''mask''\\ Read operation returns an 8-bit register's value\\ Read/write is requested via control endpoint's direction attribute being set to ''DIR_FROM_DEVICE''/''DIR_TO_DEVICE''.\\ For details on each sensor's register's function refer to the sensor's specification | |
| | |Reserved for future I²C bridge |''0xA6''| | | | | | | |
| | |RAW Mode Select|''0xA7''| | |R/W| 1 |''7:1'' - Reserved\\ ''0'' - RAW Mode |Select RAW Mode ('1') or Processed Video ('0')\\ **N.B.** This has been moved here from ''0xA5'' in FX3 version 46| |
