QUESTION
I am communicating with DPS5020 power supply to get voltage and current. The SMPS data output does not contain any delimiter at the end of the packet so I think it is causing a problem. When I query the SMPS using serial terminal program, I get correct packet every time but when I am quering using c# program, there is no data about 70% of the time. The in data packet size is 9 bytes long. I used serial_port.Read(buffer, 0, 9) but even then, there is error. Could anyone help me here ? My code is below.

...ANSWER
Answered 2020-May-14 at 08:55The problem might be caused by serial_pow2.DiscardInBuffer()
.
Unless you know there is no data you need in buffer, don't discard it.
If you make two request and just read one response, serial_pow2.DiscardInBuffer() will discard the second response in buffer.
Since your snippet is initialed by button, I can't assure how do you make request and get response.
My suggestion is not using DiscardInBuffer unless you're initializing or closing your application, or you might lose data.

QUESTION
I have a Vue.js component where there are groups of text fields ( group of a text field labelled "Start" and another text field labelled "To") bound to a Vue array ( s.timespans) .
What I want is, when I add another group of text field by adding element to the ( s.timespans ) array, all the textfields get date/timepicker. But unfortunately, now only the first group of field gets the date/timepicker and the other groups don't. What is the right way of doing this?
Thanks in advance.

Answered 2018-Jul-24 at 07:13SCIP expects rhs
to be written upper case, I don't know what the format defines exactly, but this is actually in line with how sections in mps work. We might change this in the future, but until then, just write RHS
and everything should work.

QUESTION
So I'm trying to make a frontend in android for a social network I've been doing and for some reason my ListView for the comments is not showing when the photo is a square. I saw that all the comments are showing if the photo is smaller, so it leaves some space to the comments, but the list view is getting stacked under the next view or just not shown.
The parent RecyclerView is
...ANSWER
Answered 2018-Feb-25 at 23:05If anyone has the same problem: I found out that nesting a ListView into a RecyclerView while having the layout height on wrap content will automatically size it down to 0 and i figured that even if I would want to use a list view the scrolling would be overwritten by the RecyclerView scrolling, so I bailed on the ListView (see you later). Instead of that I used a LinearLayout and I populated it in the onBindViewHolder method of the RecyclerView.
QUESTION
I discovered TypeScript recently and I try to convert my existing JavaScript code to TypeScript.
I have a function that retrieves information from a string (data
), puts it in a JSON object (json
) and returns it. But when using TypeScript and not specifying a return type, I get the following error in Eclipse:
No best common type exists among return expressions
It disappears when I add any
return type, but I think this isn't a good solution (too generic). And I couldn't find a "json" or "object" type.
My question is: what return type should I use?
Here is the function:
...ANSWER
Answered 2017-Apr-20 at 15:36You can indeed specify that you return object
(new to typescript 2.2), but you can create a type for your return value:
