python - Relationship between I2C operating frequency and sample rate setting in MPU6050 -

-

I am interested in reading the zerososcope data by Raspberry PI and Python, but I am confused about the way MPU6050 (how to set the sample rate of accelerometer)

, xeroscope;) According to I2C clock frequency to avoid incorrect reading data (for example buffer does not contain data, or write and read faster, and so on) in knowledge, each Measurement is a 16-bit word.

Is there any connection between the two watches?

I have not touched the PI since about 18 months ago with the same chip, so I do not know how things have changed in the meantime In any event, I used smbus to read the chip. Some things that I found harder, were quite slow compared to the i2c block while reading different registers. Besides, you had to shut down sleep mode Sorry, I do not have any information at the time of the clock, but if you are trying to get a well read loop right now, then it can help you use numpy There is no need to do it, but if you are planning to manipulate your samples, then it is very helpful. GL / HF 

  Import smbus import numpy # initialize bus = smbus.SMBus (1) #Sleep mode bus.write_byte_data (0x68,0x6B, 0x00) # reading in data (it can loop or Sample = numpy.empty (7) r = bus.read_i2c_block_data (0x68, 0x3B, 14) sample [0] = (r [0]

apache - 504 Gateway Time-out The server didn't respond in time. How to fix it? -

Using a form submission on an embedded iframe , the customer downloads a compressed log file Requested. The request was sent to the server, which is the compressed log files, perform some database operations and returns a compressed file. After just 2 minutes, 504 gateway time-out server did not respond timely message on browser net panel How to fix this error? The log files were taking a long time to compress, and timeout was set to 2min The error was fixed by extending the file file: # # timeout: The number of seconds before getting the time out. # # # Timeout 120 timeout 600

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
