Re: dcraw support for raw images

The bayer order is now read out of the header so is correct no matter what flips are applied in the sensor. Flips are the most likely cause of you changed filter order. Wow, I must have been testing too late last night. I swore that I couldn't get your code to work when I tried to patch it for the ...

Re: RAW output information

The format from the OV5647-based Arducam boards seems to have changed again, as I just picked up a new one from Amazon in the past month, and I had to patch current dcraw to handle images from it.

I just posted at viewtopic.php?p=1043088#p1043088 about it.

Re: dcraw support for raw images

I picked up an Arducam module (M12 mount, still OV5647) from Amazon in the past month, and it looks like another update has occurred. Current dcraw won't handle images from this. It simply returns, "Cannot decode file". I notice that the Model tag now has "RP_ov5647" (note different capitalization),...

Re: set ttyUSB0 using stty

Do you get the same issue if you try something similar on a normal Linux PC?

What USB-serial interface are you using? In a few hours here I will try my own USB-serial interface (FTDI Basic) on Raspbian and see if I have the same issue.

Re: set ttyUSB0 using stty

Silly, possibly irrelevant question: Do you as a normal user have write access to that device? Is it any different if you precede the commands with 'sudo'?

Re: Interfacing with ShiftBrite via sort-of-SPI

If I am bit-banging SPI here, what would I be doing it with? A handful of GPIO pins for MOSI, latch, and clock? Yes If I'm doing it in user-land, I wonder if I can still get the clock and data stable enough. That is the whole point of the SPI interface, you don't have to have stable signals, they j...

Re: Trouble typing

I have had issues typing as well on my Raspberry Pi with one particular keyboard. It takes the form of keys 'sticking' though I'm not touching anything or of a keystroke not registering until I hit other keys afterward.

Re: Interfacing with ShiftBrite via sort-of-SPI

Finding a GPIO line that I can toggle quickly enough (for a 500 kHz SPI clock, that's in the microseconds). I'm told that in userspace this is basically impossible. No you can toggle GPIO lines at over 5MHz. I think what you are doing is mixing up the minimum and maximum timing on the signal lines....

Interfacing with ShiftBrite via sort-of-SPI

I am trying to interface the Raspberry Pi with a chain of ShiftBrite modules. The ShiftBrite speaks SPI, but with the catch that you also need a latch line that needs some fairly accurate timing (at a minimum, you must drive the latch high, hold it for a time that's measured in nanoseconds and depen...
