Checking data before reading (non-blocking)

[TelegramXPlus]

I would like to combine serial.nim and Arduino for a project of mine yet the line

port.readLine() is blocking and unless I create a second thread for handling other things the code does not work (it just waits for data). I would like to have something like Arduino Serial.available() or python ser.in_waiting so that I don't have to split the code into multiple threads

Hi, Yes the serial port methods are all blocking. There isn’t currently a way to get the amount of available data. I’d be open to adding one so long as there is a way to do so on all of the supported platforms.  However, it may be worth trying the AsyncSerialPort. It’s read function returns a future which you could use to read asynchronously which may be one option.

Alright, thank for the suggestion. I'll see the async version but I think that for now I will use two separate threads for reading and writing data using serial (not very safe, but it does the job). Thanks again.

I might also use a lock system to be safe and to keep the code as simple as possible.
