How to get data from C++ program memory in Python

My current situation is like this, the C++ program produces an array, I want to put this array into python to do some operations, and then the data after python processing is returned to the C++ program to continue processing.
How do I do this?

Re: LCD and Gyroscope

You are right, what I mean is that a 3D model is displayed on the LCD, and the viewer can drag and drop the model with his finger to achieve multi-angle viewing. Inspired by the everyday use of cell phones, when we look at an object that can be rotated, we can use our fingers to rotate it. The scree...

Seeking the suitable robotic arm

I'm recently interested in robots and robotic arms, and I'm looking for a robotic arm that can communicate with my touch screen through UART. I have designed the GUI interface. By the way, should I choose a 3-axis robotic arm or a 6-axis robotic arm?

Re: Can lithium batteries be recharged?

Ok, I will not charge it and I will buy a new replacement if necessary. But I think it could work for a long time.

Seeking tips about card readers

I read an article about card reading a few days ago, but I don't understand how it works. Suppose I want to make a project that can store, read and unlock a card, what do I need to prepare?

LCD and Gyroscope

I am using Stone's LCD if the LCD itself does not come with a gyroscope, but I want to accomplish some functions like being able to rotate 360° to view a model on the LCD. Suppose I connect an external microcontroller and an MPU6050 module, is it possible to achieve this function?

C++ how to wait for input at runtime

Normally with getchar and scanf, etc., the program will stop and wait for input. How can I run other functions while waiting for user input?

Re: need tips on building a large screen calendar.

I don't know if you've solved this problem, but I've also recently made this touchable calendar a project option, only I will do a much smaller project than yours. I will probably only use an 8" or 10" screen and already have options. You want to use a very large size touch screen might be a big cha...
