22 | /* Some documentation about various registers as determined by trial and error. |
23 | When the register addresses differ between the 7202 and the 7311 the 2 | |
24 | different addresses are written as 7302addr/7311addr, when one of the 2 | |
25 | addresses is a - sign that register description is not valid for the | |
26 | matching IC. | |
27 | ||
28 | Register page 1: | |
29 | ||
30 | Address Description | |
31 | -/0x08 Unknown compressor related, must always be 8 except when not | |
32 | in 640x480 resolution and page 4 reg 2 <= 3 then set it to 9 ! | |
33 | -/0x1b Auto white balance related, bit 0 is AWB enable (inverted) | |
34 | bits 345 seem to toggle per color gains on/off (inverted) | |
35 | 0x78 Global control, bit 6 controls the LED (inverted) | |
36 | -/0x80 JPEG compression ratio ? Best not touched | |
37 | ||
38 | Register page 3/4: | |
39 | ||
40 | Address Description | |
41 | 0x02 Clock divider 2-63, fps =~ 60 / val. Must be a multiple of 3 on | |
038ec7c7 | 42 | the 7302, so one of 3, 6, 9, ..., except when between 6 and 12? |
327c4abf HG |
43 | -/0x0f Master gain 1-245, low value = high gain |
44 | 0x10/- Master gain 0-31 | |
45 | -/0x10 Another gain 0-15, limited influence (1-2x gain I guess) | |
46 | 0x21 Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused | |
8a5b2e90 HG |
47 | -/0x27 Seems to toggle various gains on / off, Setting bit 7 seems to |
48 | completely disable the analog amplification block. Set to 0x68 | |
49 | for max gain, 0x14 for minimal gain. | |
