Re: raspistill --roi unexpected behaviour

Oh, thank you @gordon77! I misunderstood the documentation. However, I feel myself a bit "limited" by using it in this way. For example, let's say that I want to "split" the image into two halfs (top and bottom) and get only the bottom part. Would it be possible? Because modifying the resolution jus...

raspistill --roi unexpected behaviour

As far as I understood from the documentation, zoom is composed of (x, y, w, h) Let's say we have an image of w, h = (3280, 2464) . If I use a zoom = (0.25, 0.25, 0.5, 0.5) I expect to capture images where the center part matches with the center of the full image (like a x2 zoom). And the result is ...

Re: GPU/CPU temperature limit for RPI3

Thank you very much for your answer. It's good to know that my RPI is more than 10ºC away from that limit. However, my question is more related to how many time the RPI might work until it is broken. In other words: Suppose that my RPI is working 5 years (8 hours per day, 365 days) if the temperatur...

GPU/CPU temperature limit for RPI3

Hi everyone, I am using the RPI3 and the picamera to process the video stream. The temperature of the CPU and GPU ranges from 50º to 72º Celsius, using or not a tiny fan (I am measuring these temperatures using the thermal_zone0/temp and vcgencmd measure_temp commands). However, I wonder which one i...
