im a beginner in embedde rust on a raspberry pi. Need some help for loading code via toolchain on the pi 4. Tanks for helping
i hope someone can help me with that or show me where i can get a guide
I suggest using this video. It also goes over gpio.

I'm having trouble wiring and coding this glcd to run on my pico. I cant find very much on the internet about getting these things to run on a pico. The places that I have looked, all have a different wiring schematic- some say dont connect r/w pin to pi, while others say you should. I found a github page that has some code, but im not sure if this wiring will damage my pi. Also once ive got these libaries, there is no explanation of how to use them. This libary is written in micropython, but is for the ESP826, for which I dont know if the gpio pins are the same. Also, when looking at arduino examples, they use D7-4 pins on the lcd, whereas this libary says not to.
Basically im confused and dont know how to get this glcd working. Any help would be much appreciated.
I have an Ubuntu 18.04 server on a laptop that has bluetooth adapter. I also have a led strip from China which also has a bluetooth adapter. I can control my led through an app on my phone.
Is there any way to successfully connect to the led strip with my linux laptop and control it?
If so, how could I know which code / key (or I don't know how this bluetooth control works, sorry) is assigned to a color? So basically, I don't know what command should I send to the strip.
Can anybody please write an example program for me?
I tried the rfcomm, bluetoothctl and bluetooth-sendto but they didn't work. :(
Hope we can solve my problem.
You'll need to reverse engineer your device :
with little research I found this

I’m looking to essentially use two devices: raspberry pi 3 and Mac 10.15. I am using the pi to capture video from my web cam and I want to use my Mac to kind of extend to the pi so when I use cv2.videocapture I can capture that same video in preferably real-time or something close. I’m programming this using python on bout devices. I thought of putting it on a local server and retrieving it but I have no idea how I could use that with opencv. If someone could provide and explain a useful example, I would greatly appreciate it. Thank you.
To transfer a video stream, you could use instead of a custom solution a RTMP server on the source machine feeding it with the cam source and the target opens the stream and processes it.
A similar approach to mine is widely implemented into IP cameras: They run a RTMP server to make the stream available for phones and PC.
I got my Raspberry Pi 3 quite recently and have made some basic projects. I'm looking for a method to create a website (on my laptop) and control my raspberry pi through that - well, more just a circuit attached to it. Would that be possible? If so, how would I approach it?
Depending on the language you want to use for the project, you will want to find a gpio library to control the GPIO pins. You would then want to wrap the calls in a webserver. Some examples of the libraries:

I am doing my master thesis and one of the important things for me is to transfer the recordings of pressure and temperature from a patient simulator to a PC. From the sensors, the information is taken by the raspberry pi3. I am using raspberry pi3 because it has inbuilt wifi option. Now I have to transfer the data from the raspberry pi to the PC wirelessly using python programming. I am new to python and I have absolutely no idea how to do this. Could anyone help me with writing the code so that I could at least send some data from where I could adjust the bit rate and other things according to my requirements?
Take a look at sockets, a simple client - server communication is really easy to do :)
