Ixus 185 + CHDK 100a

I am using google translator. I hope you excuse the translation. I will also write in Spanish.

I bought a Canon IXUS 185 camera. I bought it because I want to use CHDK, especially for the PTP system. However, I ran into problems that are not yet resolved and appear in camnotes.txt (CHDK v 100a)

"TESTED

***************
Filewritetask and movie features are not supported.

KNOWN BUGS
**********

When I inquire on the internet, PTP is apparently related to FWT. As there is no FWT in Ixus 185 (chdk 100a), I cannot transfer photos to the PC with script or live view.

My question is this: Is it a temporary limitation or will it have a solution soon? I need to know, since I bought that model and I can't sell them at the original cost, but at a 50% lower price.

He comprado una cámara Canon IXUS 185. La compré porque quieto utilizar CHDK, especialmente por el sistema PTP. Sin embargo, me topé con problemas que aún no están resueltos y aparecen en camnotes.txt (en la versión 100a de CHDK)

Cuando indago en internet, aparentemente está relacionado PTP con FWT. Al no haber FWT en Ixus 185, no se puede transferir fotografías a la PC con script ni hacer live view.

Mi duda es la siguiente: ¿Es una limitación temporal o tendrá solución pronto? Necesito saber, ya que compré ese modelo y no puedo venderlas al costo original, sino a un precio 50% menor.

No problem, I think it worked

Without FWT, you cannot remote shoot jpeg files. This means the chdkptp 'rs' command will not work with jpeg. You can use rs with DNG, but jpeg will still save on the card.

You can shoot, download file and delete. It's just a bit slower. In chdkptp, you can use shoot -rm -dl to do this.

FWT doesn't affect live view. If there are problems with live view on this port, it's different problem.

I think FWT can be implemented on this camera. If you are willing to test, I will try to make a test build in the next week or so.

I am testing several capture software with chdkptp. With an IXUS 185 I get the following error: 0x2ff.

I was able to take pictures remotely and they are saved in the SD memory without problem. However, I need to know if the picture worked or if I have to do it again.

I will try to change the format to DNG in CHDK to get a possible solution.

This is not related to FWT.

It means there was an error with the connection. Maybe the camera crashed, or some other software interfered.

Are you using windows or linux?

What do you mean by "several capture software" ? Other programs, not chdkptp?

If you are using chdkptp, you can use

Code: [Select]

shoot -dl

to shoot and then download the file.

DNG is quite slow, and might not look like jpeg.

@aguiluz
fwt seems very similar to another camera, so it was quick. I posted a test build in https://chdk.setepontos.com/index.php?topic=13837.msg142236#msg142236

He instalado el CHDK parcheado en mi memoria. Todo bien.

Aún no funciona la transferencia de fotografías a la PC (PTP) porque, según entiendo, es necesario tener FWT, el cual no está en IXUS 185.

En software de terceros (que han automatizado chdkptp con interfaz gráfica o comandos sintetizados) reconoce la cámara, hace shoot, pero no transfiere las imágenes a la PC.

Se supone que IXUS 185 es la misma ELPH 180 con la única diferencia en el sensor. ¿Se puede partir de ahí? con Elph 180 no tengo ningún problema.

Ahora bien, el error común tiene que ver con 0x2ff. Este error aparece en el FAQ de PTP extension https://chdk.fandom.com/wiki/PTP_Extension

Quote

Download/upload fails with code 0x2ff or the camera crashes when you try to transfer a file
Perhaps you didn't correctly specify the file on the camera. Always use the full path and start with a capitalised 'A'. For example: "download A/DCIM/100CANON/IMG_1234.jpg test.jpg"
note this mainly applies to ptpcam, chdkptp corrects the names for you.

Intenté solucionar esto deshabilitando el "eco mode" y deshabilitando el apagado automático de pantalla. Funciona a veces, pero la cámara falla.

En los diferentes software que automatizan chdkptp me aparece ese error 0x2ff. Y si aparece en el FAQ de CHDK, entonces algo no está funcionando bien en la compilación.

¿Se puede solucionar viendo el firmware de Elph 180?

I have installed the CHDK patched in my memory. All good.

You installed test build https://chdk.setepontos.com/index.php?topic=13837.msg142236#msg142236 ?

If yes, did your run the test?

Code: [Select]

chdkptp -e"exec require'camtests'.runbatch{shoot=true}"

The transfer of photographs to the PC (PTP) still does not work because, as I understand it, it is necessary to have FWT, which is not in IXUS 185.

The test build has FWT, but there it could have mistakes.

0x2ff means the connection is broken. It does not say why.

To fix, we need need more details.

Are you using Linux or Windows?

Does 0x2ff always happen when you do one thing, or is it random?

If it happens when you do one thing, what is it: Shoot, download, something else?

When 0x2ff happens, does the camera turn off?

If the camera turns off, can you get a ROMLOG: https://chdk.fandom.com/wiki/Debugging#Camera_crash_logs_.28romlog.29

It's a different camera. First, we need more detail about when the 0x2ff happens. Then, maybe comparison will help.

I'm using windows.

PTPCamGUI: Works great. Shoot, live, filters, menú controled from windows, video, download, etc.

Nice (I'm the co author of this app).

Nevertheless the program is obsolete. This program is no longer maintained. Better is to use chdkptp.

ChdkPTP test

No shoot, no video, no live

Download images on SD card, yes.

Edited:

I thought the REC button on chdkPTP was something else. I clicked and everything works very well.

Shoot, I can see the screen live, I can record video, and all that.

With remote capture I can take a photo, but it doesn't download in jpg to the pc; The software freezes. With DNG shoot at a distance, yes. It works very well.
