QUESTION
I have a device for taking spectrometer measurements. A raspberry Pi is used as a shell for a GUi and communicates over serial (USB) with an Arduino to read spectrometer values. The RPi sends a string to the Arduino to tell it to read the spectrometer. During each measurement all spectrometer pixel values (288) are stored to a uint16 buffer then sent back over serial to the Pi which waits for at least 3 seconds to read data from the Serial. right now it takes about 0.3 seconds for one measurement (including time for RPi to tell the Arduino to take a measurement, the time it takes to actually read the spectrometer, and then send all of the spectrometer values back over Serial to the Pi). I have tried to implement this using I2C but it wasn't much faster (I had to send each value byte by byte). I am trying to implement this with SPI (which will hopefully be faster but don't have any experience with this interface). Is there a simple way to tell the Arduino when to read then send a large buffer of data back to the Pi? (instead of sending it over piece by piece?)
(This is the most important part of my code, there is more to it but hopefully this gets the point across)

Answered 2021-Mar-25 at 11:18My suggestion in the comments was to send the data as binary rather than as ASCII strings, because if you imagine the 16-bit sample 10,000 it requires 2 bytes to be transmitted, whereas if you make it an ASCII string, it takes 6 bytes if you include the comma required to separate it from the next sample:

QUESTION
So in my navigation bar I have tried to add an icon. However, even with the correct path given (shown with fuji.png) the image gives a 404 (NOT FOUND).
The error message in inspect element is:
GET http://127.0.0.1:8000/icons/fuji.png 404 (Not Found)
Does this mean that instead of a relative path it looks for a URL path?
navbar.html
...ANSWER
Answered 2020-Aug-01 at 12:50You need to set up a folder for static files in settings (like STATIC_URL = '/static/'), before trying to load them. Then, you can create icon folder there and use links to access the images there. The full guide is here.
QUESTION
I have a problem. I want to describe an abstract optimization model for general production planning. I have a huge excel data-frame with lots of values for parameters. I want to import them, but there is a constructing error for the parameters with 3 indices. I don't understand the failure, because the preview for the values are perfect.
FYI: if i import parameters with one or two indices, then there are no error messages. And if i initialize the values for parameters (also with 3 indices) in my jupyter notebook there are also no errors. But my wish is, that the data-frame and the jupyter notebook are separated.
Here's an abridged fictional example of my problem:

I believe your problem in the above model is that you are setting up your set m.T as strings for members instead of integers.
Here is an example of what I think is going wrong, using a ConcreteModel as an example...
QUESTION
I'm trying to create a data tree from strings that are expanded by at least 1 letter that is reachable from the current start word. My starting word in this case Dog and the ending word i want for this case would be maybe cat. I have to check that the word from the dictionary is the same size and not already in the vector words and also that if it only 1 letter difference. Below I have tried already implementing this type of thinking but I think I'm missing something crucial. That I need help looking for or maybe add to my code.
...ANSWER
Answered 2019-Oct-09 at 23:48To avoid an infinite loop, you need to remember words that you have already seen. In the following code example, I use an unordered_set for that (add #include .

QUESTION
I have problem with adding loyalty card to google pay app using google play services api. I have got account verficication after google pay request, but I'm receiving 400 in logs.
Can't find what's wrong...
Code below has been written following this guides:
https://developers.google.com/pay/passes/guides/overview/basics/typical-api-flow
Attached code (Take a look on comments, it's important)
...ANSWER
Answered 2018-Dec-21 at 18:14I was having this problem as well. The error message isn't very informative. Your app needs to be whitelisted by the Google Pay team. You need to contact them at https://support.google.com/pay/merchants/contact/interest and provide the following:
- Issuer ID (this is on your merchant account page)
- App package name (this is found in your AndroidManifest.xml on the manifest parent element com.companyname.appname)
- SHA1 Fingerprint (This can be found by following the instructions outlined here: https://developers.google.com/pay/passes/guides/get-started/basic-setup/native-android-sdk)
So I finally got this to work, in the merchant center under the general area I changed the status field from DRAFT to UNDER_REVIEW. It immediately changed to approved and I could save the loyalty card.
QUESTION
I am a bit new to python and I am working with miniWOB from OpenAI. I want to print out with cv2 what my observations are for my agent. But really doesn matter. My problem is I do not know exact which data type I receive from the gym for my "observation". But I want it as a simple 3Dimensional numpy array. This format I can print out using cv2. So can anybody help me to convert my < class 'list> observation to: < type nunpy.ndarray>? I already tried observation = np.asarray(observation) but then I got this error: "mat data type = 17".
...ANSWER
Answered 2017-Oct-10 at 10:03Not entirely familiar with world of bits, but based on the output, I would assume that you have an array of observationS (in your case just one) and each observation consists of a dict, probably you could have other sensor input as well, but in your example it just contains the visible observation 'vision' (i.e. the pixels). So to get the array you want you select the first element and extract the "vision" element:

Actually I have this.

Answered 2017-Jul-11 at 19:37Your addAction is completely separated from indexAction and these are different requests, so you cannot expect to keep value of $wob property between requests.
In yours example you can make parent only inside the same action:

Since I am fairly new to Java, I only know enough to make variables, import stuff and some other stuff; but what I do not get is why the begin() function is not running and any help that can explain whats going on and possibly rewrite it in a better way would be greatly appreciated!

Just like Ousmane Mahy Diaw mentionned in his comment, begin is a class, not a function. That is basic Java knowledge, so first I would recommend practicing doing your chess with command line. An Interface should be a separate effort.
There is a lot of problems with that code. I recommend using Netbeans IDE. It could help you out when it comes to basic errors.
I recommend doing like so when it comes to building Interfaces with JFrames:
