I was wondering if there was anyone around these forums that could help me out with some issues I seem to have. If you are willing to help me out for maybe 5-10 minutes, I would be very thankful.

Whats your problem then?...

I wanted to talk to someone about this. It's more for my general knowledge about serial port programming but a specific question on PyQt4.

 

For PyQt4 I want to setup an array of radio buttons that when I toggle on and off their background colors change and performs some other actions. I want this to look as close to a grid as I can, as I will also have labels to describe each row/column. I just am new to PyQt4 and I'm not sure what module I can use for this task.

 

For serial Port Programming I'm using PySerial. I don't understand how the interaction works though. I have a status packet, with serial commands but when I have a new serial command to be issued, does it resend the whole status packet? I guess just a general explanation of how serial data controlling a product works would be helpful.

I can't help with the PyQt but i might be able to help with the serial.. 

Can you show us some code please and what are you sending the data to?

I dont have much except GUI code for the time being. I am sending data through either a RS-232, RS-485, or USB port. All I'm sending is a serial command that is ten bytes long. Something like 3A3031350D in hex. I am receiving a 24 byte status packet in return. I have looked into PySerial, I just have no experience with it and am not sure how to go about it.

@Enderman @ @Tigerbomb8 

 

I have quite a bit of the UI set but I need help on the PySerial part. If any of you could PM me or something I could just use five minutes of your time to bounce questions off you. Thanks <3

you could ask those questions here

more people will read them, so more people could answer them

plus, it's more community-friendly and more internet-friendly to have a public discussion about problems, so that if someone on the internet has the same problems as yours, he will find answers here thanks to you and the community

I pretty much stated above what I was having difficulty with.

I am receiving a 24 byte status packet in return. I have looked into PySerial, I just have no experience with it and am not sure how to go about it.

I just basically need help here. I don't know how to set my port value to accept any of those connections and I don't know the proper way about sending/receiving information using serial ports and this module.

I am making a custom arduino GUI using pyqt and pyserial. In my gui I open aother window of serial monitor and connect it to serial port via pyserial. But the process remains active even after I close the serial monitor window and connection to serial port remains active for which I couldn't establish a new connection from any other source.

any solution?

Aww was scrolling through the thread and thought Ciccioo was back.

 

@Spandan_Samiran Make sure you're calling your_serial_port.close() when you close the window.

 

Also the obligatory don't necro threads that are 2 years old.
