python - How does PySerial work? -

To read the serial data from my Arduino, I have the following Python script: Serial ser = serial.Serial Import ("dev / ttyACM1", 9600) ser.timeout = 2 ser.readlines () On the other hand I started my Arduino with a program Which sends each voltage readings in 20 seconds. Arduino starts sending those readings from the moment that it is tilted, then after 20 seconds it closes and does not send anything. Now what I have noticed is that I can read those 20 voltage values ​​using the first script I need. That is, I can hook up Arduino, wait for a few minutes, then read in the values. I think the data is being stored anywhere. I think it is not being stored on Arduino, but somewhere on my laptop. I have come up with a few questions which I hope the community can help me: Where to get data from PySerial (Arduino or some buffer on my laptop) Happening? How much time is there data stored in this place? Is there a way to clear this place before reading the values? ...

java - Display 2D text on screen simply -

For the last hours I have been looking through forum posts, blogs, videos and various other websites to know how it will be done. How to display the text on the screen is not very easy to do with what I've seen (maybe this once you know how to actually do it) I have posted this question here (With some regrets) have decided.

javascript - How to abort a failing Q promise in Node.JS -

Assume that I am creating a registration stream, and I have something that looks like this: / P> Q.nfcall (validateNewRegCallback, email, password) .fail (function (err) {console.log ("bad email / pass:" + err); return null;}) .then Function () {console log ("valid!");}) .done (); If my registration fails, then I want to capture it, and I will die. Instead, I'm seeing both "bad email / pass" and "valid". Why is this, and how can I stop in the first failure call? unsuccessful Handler grabs rejected promises, but then a complete Returns the promise ( null in your code), because the error was already handled.? | So what can you do against this? To revert the error to reject the returning promise it will be the reason for throwing it done . Q.nfcall (validateNewRegCallback, email, password) .file (function (err) {console.log ("bad email / pass:" + mistake); throw away;}). Then (function () {console.log (...

Automatic addoninstall (Hybris 5.1) -

We are using addon support to increase ycommercewebservices. It's a cool and convenient feature, though we have a problem - we need to execute the ant task addoninstall on every machine so that we can add our dependency dependency to the ycommercewebservices template: ant addoninstall -Daddonnames = "someAddon" -DaddonStorefront.ycommercewebservices = "ycommercewebservices" What is the best way to automate this process? You should not have to be made from ycommercewebservices every time. This is a template extension, so starts with 'y' Generate a new extension using yemspacewebservices using extgen. Add your extension to the new extension Do not touch this new extension directly in your repository template so there should be no need to automate it. But how difficult is it to automate only an ant task?
