Re: Raspistill timelapse. Images get progressively darker

I'm now using raspistill -t 1000 in a while loop, taken a couple of thousand pictures with no problems, all exposed correctly, all taken outside in bright sunlight. With no other delays in the loop I get a pictures at 2 second intervals, will try -t 500, but is there anything else I can try to go fa...

Re: Raspistill timelapse. Images get progressively darker

jamesh - ah good point! Cheers, I'll check that. Questionario - I've haven't had problems with the file-system yet, but then I am writing the images to a USB drive, not the SD card. I also changed the while loop to a for loop so it'd eventually end as I was running it in the background. (Q: how does...

Re: Raspistill timelapse. Images get progressively darker

I'm having the same problem - timelapse images get progressively darker (using -tl 1000 argument). Replaced it with a while loop script executing the command: raspistill -n -t 0 -o image-x$.jpg Anything less than -t 5 (or nothing at default is 5), gives under-exposed, dark pictures. 5s is too slow f...

Re: Enable both I2C Busses

Bill - thanks very much for posting that code, it does exactly what I want it do and worked first time!

I can now move on to the next stage of my project... :D

Re: Enable both I2C Busses

Hallelujah... I have been able to access I2C-0! But not on P5... on S5.

Re: Enable both I2C Busses

Hi I've just confirmed that I too need to access both i2c busses. I have sample code which will detect my device on i2c-1 on P1. I've tried attaching my device to i2c-0 on P5. I believe that the pins to use are GPIO28 (SDA) and GPIO29 (SCL). I've modified my sample code to use i2c-0 but it doen't w...
