Py serial library install#
ArduinoIDE is running processes under the different user than it did install libraries. Basically it means, that the problem is in the rights. At the beginning I was running into the same issue, however I have soon discovered it is very important how you install the Python libraries (if is it as a root user or a regular user). I did use makeEspArduino tool from Peter Lerup (plerup). I am still not able to send the compiled sketch into the ESP through the ArduinoIDE, however I have managed to get it work with the help of external tools completely independent of Arduino software. OK, I don't remember how did I sort it out last time, but now I have ran into the same problem again when I made a fresh new install of Big Sur.

I'm new to this Arduino community.Īnd there's an error while I'm trying to upload a sketch that I made.īy sketch, I mean any sketch. i did see that there is a sticky dict and tried to add myPort to it, but i kept getting errors in the other component when i try to use the object's methods.Hi.
Py serial library how to#
any advice?Ģ) I'd like to share this port with other components (or at least break up the functions of opening/closing the port and read/write, not unlike how the firefly components are organized), but i have no idea how to share an object instance between components. i read through the discussions and didn't see any definitive answers to this problem. it seems rhino is holding the port open, as i have to re-start rhino to get it working again.
however, if i try to re-open it, i get an access denied error. here are my questions:ġ) I can open the port and then close it. Cannot close port." if myPort.isOpen != True: print myPort.name + " is closed" Cannot open port." if myPort.isOpen() = True: print myPort.name + " is open" if z != True: try: myPort.close() except: print "Something went wrong. Import serial myPort=serial.Serial() myPort.baudrate = x myPort.port = y if z = True: try: myPort.open() except: print "Something went wrong. here's an example of a working (mostly) port open/close script (x=input param for baud, y=input param for port name, z=boolean input param for open/close):
i'm using the pyserial library to do the comm, and i can get it to work within one script. i have used andy payne's general serial components from firefly, but i don't think they'll work for what i want to do, and in general, i want to know how to do this from scratch. for instance, when i send a command/data, i need to wait for an appropriate response before sending another. but first allow me to explain what i'm trying to do: i have a serial device i want to talk to, but i have to do it using some sort of handshaking. i am relatively new to python scripting in the context of grasshopper, so i have a few questions. I'm trying to program a serial protocol using the ghpython script component inside grasshopper.
