hi
wish you all the best.

i have a problem. i want to send data from serial port by ch340 usb module to arduino ide and show it in arduino plotting but it doesn't work!
note that i don't have arduino board to connect so there is no hardware all i have is arduino ide and ch340 usb to serial module.
i am sending float numbers in ascii format to serial comport and i want see that numbers in chart in arduino plotting but it doesn't work i add that comport in arduino ide in select board
but the plot does not show anything

please help me
thank you.

Welcome to the forum

What format are you using when sending the data ? Please post some examples

Never post in the uncategorised section. Please read the description of a section before posting.

You can not do what you want to do without any hardware. You need some sort of hardware like an Arduino.

my format is like
0.1 -0.1 2 0.3
and so on

i know. i just didn't know in what category should i say it so i chose uncategorized

i have seen some one did it before. i don't know how . i know it is possible but how ......

But you didn't actually read the description of the category which said:-

DO NOT USE! Please select the appropriate category for your topic.

No nether do I.

How do you know it?

OK but then you say

So if you have no hardware, then what does it matter that it is a ch340 or anything else?

If you do have a ch340 usb to serial module then you have hardware so why say

there is no hardware

You are not making any sense.

What software are you using at the PC side to send data into the Arduino IDE?
Can you see this source in the list of ports in the tools menu of the IDE?
Can you explain exactly what you are doing in trying to get this to work?

Welcome

Please describe in detail (and we mean: DETAIL) what that means. Do you get errors, does it not display, ...?

Your description is vague. For starters, you do not mention what is sending the information. If it's an application on your PC, be aware that only one application on the PC at a time can use a serial port. So if you have an application to send and the IDE plotter to receive, it will not work. You can use two modules and to get two serial ports on your PC and connect the TX of the one to the RX of the other one.
