FX3 Host Vendor Command Reference
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 |
| 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 modifieddata - 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 maskRead 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 - Reserved0 - RAW Mode | Select RAW Mode ('1') or Processed Video ('0') N.B. This has been moved here from 0xA5 in FX3 version 46 |
