how can i monitor the serial port for reading

[zhanghuanqian]

hello:
I want to read arduino board by serial port. And how can I monitor when the buffer has some data arrived? I try it by "wait for 3000 milliseconds", but I loss some data. how can I get total data?
thanks!

Code: Select all

open driver "COM5:" for binary update
wait for 3000 milliseconds//if read directly, it will get nothing because Arduino will restart after a cup of and then send data by serial port
read from "COM5:" for 128 uInt1
put it//it can get part of data , not all data
close driver "COM5:"

And, the progress not know when the datas are sended by Arduino board.
so, how can i monitor the serial port for the comming datas and read them crectly?
thanks!

My Arduino board send a number every 100 milliseconds from 0 to 65535, but the LC process read the data like "50 48 51 57 51" ,it is not right!
Is it a interrupt or another methods to monitor whether the data is send by Arduino or not?

I fond a thread here:http://forums.livecode.com/viewtopic.ph ... er#p123143

I try it ,but Unstable!

mm, perhaps it is not clearly.
I write a program by LC7.0(os:win 7) to read the data sent by Arduino board, the data is large and random. So I cant deal with it.

Check this two files
I made this about a year ago, and i uploaded to facebook, livecode latinamerican group
hope this can help you

the two files (arduino and LC) are the ones with the name full_control_01

www facebook com/groups/livecodela/files/

just add the dots in the right place in the web address

thanks very much!

You are welcome

Please, let me know your experience working with the codes


Another thing, i recommend you to start playing with the ESP8266 module, is like arduino, but wifi, that means, no cables attached!
