|
| 09:59 | preetimenghwani[ | For T871 do we need to do post route simulation of both deserializer and serializer or only deserializer?
|
| 09:59 | preetimenghwani[ | Currently my serializer is in test bench

|
| 10:49 | Bertl | preetimenghwani[: that's okay, no need to implement the serializer
|
| 10:50 | vup | morning :)

|
| 12:18 | se6ast1an | hi!
|
| 12:18 | se6ast1an | Bertl: you around?
|
| 12:18 | Bertl | yup
|
| 12:19 | se6ast1an | great
|
| 12:19 | se6ast1an | jan so what is your current status?
|
| 12:19 | schmoggie | i build my workspace as of recent ubuntu in a parallels vm
|
| 12:20 | schmoggie | and compiled a new kernel.
|
| 12:20 | schmoggie | and read thru the other "reverse engineering" things.
|
| 12:21 | schmoggie | also getting a sony-e camera + lens to do some serial tests
|
| 12:21 | se6ast1an | would you plan the next step to be listening in on emount communication with a known working camera?
|
| 12:22 | schmoggie | yes. but also in parallel try to adopt the other emount hacks in a trial on the apertus
|
| 12:22 | schmoggie | hence my question where is the entry point for the lens comms, e.g. where can i query/program the pins
|
| 12:23 | Bertl | probably the best way here is to either reuse an existing or design a shield suitable for lens control
|
| 12:23 | Bertl | really depends on the required interfaces and voltages
|
| 12:24 | schmoggie | okay, so at the moment it is the e-mount connected no where ( havent taken the mount apart)
|
| 12:24 | Bertl | do you know what control signals you need and what voltage levels they have? what about power supply for the lens-system?
|
| 12:24 | Bertl | correct, the current e-mount is only passive, no electrical connections yet
|
| 12:25 | schmoggie | ah
|
| 12:25 | schmoggie | according to https://github.com/LexOptical/E-Mount
|
| 12:26 | pratyush | is here a discussion realted to lens auto focus going on ?
|
| 12:27 | schmoggie | so it's 10 pins.
|
| 12:27 | schmoggie | 750kbaud , but init is 1.5mbaud
|
| 12:28 | schmoggie | so 5.0V, VCC lines are 3.15V, 2 serial pins
|
| 12:29 | schmoggie | so a serial uart,via i2c maybe ?
|
| 12:30 | Bertl | 1.5mbaud is no problem at all, the question is more about the 5V
|
| 12:31 | Bertl | how much power can the lens system draw for example
|
| 12:31 | Bertl | do the communication lines work with 3.15? V
|
| 12:31 | Bertl | etc
|
| 12:32 | Bertl | http://camera-wiki.org/wiki/Sony_E_mount_reverse_engineer
|
| 12:32 | Bertl | this might have some useful infos
|
| 12:32 | schmoggie | https://docs.google.com/document/d/1iw54nzrF0bzQgLINpcP9F8Odd0N5cd7LjlwCDPTNZK0/edit#heading=h.dk3gmdgcv9gp
|
| 12:34 | Bertl | okay, so the 3.15V logic can be handled by one of the existing shields, but it requires a regulator or 3.15V input
|
| 12:35 | Bertl | leaves the question how much power the lens can draw on LENS_POWER and LOGIC_VCC (or is that an output?)
|
| 12:37 | BAndiT1983 | nope, looks like negotiated 5v or unregulated 6.4
|
| 12:37 | BAndiT1983 | *7.4v
|
| 12:38 | se6ast1an | power usage will need to be measured with the camera/lens sniffing adapter I assume
|
| 12:39 | pratyush | left the channel |
| 12:39 | BAndiT1983 | nice, just seen the link to apertus on wiki
|
| 12:39 | BAndiT1983 | maybe the sony service manual is listing the voltage also, at least for reference
|
| 12:42 | BAndiT1983 | page 4-1 has lens related things on the left side -> NIMB contact unit
|
| 12:43 | BAndiT1983 | 4-3 at right-bottom has lens power control
|
| 12:43 | BAndiT1983 | *bottom-right
|
| 12:45 | BAndiT1983 | 6-21 has a motor driver, but a bit hard to distinct
|
| 12:46 | BAndiT1983 | and 6-22 lens interface
|
| 12:47 | schmoggie | that will i do. have an arduino shield
|
| 12:48 | schmoggie | (power measurement)
|
| 12:48 | schmoggie | i would assume no more than 100mW
|
| 12:49 | se6ast1an | I thought of just using a volt meter but something more sophisticated is even better I guess
|
| 12:49 | BAndiT1983 | if i decipher it correctly, then i also see 4.8V on 6-22
|
| 12:49 | Bertl | just be careful with any arduino, it's not clear how strict the 3.15V really is
|
| 12:49 | BAndiT1983 | and 3.1V
|
| 12:55 | XYZ123 | left the channel |
| 12:56 | se6ast1an | ok schmoggie, all questions resolved for now?
|
| 12:57 | se6ast1an | anything else we can do/help to support you?
|
| 12:59 | Bertl | might be worth looking for an e-mount datasheet (even if it doesn't have details, it might specify the maximum current or so)
|
| 12:59 | BAndiT1983 | schmoggie: have you looked at dyxum forum already, quite a long thread, but i suggest to read the last 4-5 pages, quite interesting approach
|
| 13:01 | schmoggie | ok will do.
|
| 13:01 | schmoggie | url ?
|
| 13:02 | BAndiT1983 | is also in wiki, but here it is -> https://www.dyxum.com/DFORUM/emount-electronic-protocol-reverse-engineering_topic119522_page11.html
|
| 13:06 | se6ast1an | ok going out for a bit, afk
|
| 13:07 | Bertl | with the dog?
|
| 13:08 | BAndiT1983 | nah, just a leash is already enough, can tell the police that dog ran away
|
| 13:08 | Bertl | stiff leash with wirecore -> invisible dog :)
|
| 13:09 | BAndiT1983 | now you know which companies will get bigger income at the moment
|
| 13:09 | BAndiT1983 | TP and invisible dog leash manufacturers
|
| 13:09 | schmoggie | heh
|
| 13:10 | schmoggie | also making some food and then hunt for a cheap e camera lens

|

|
