Recently, I bought a Raspberry Pi 3b+, ready to put a. Net core crawler on it and run it.Buy before thought Raspberry Pi because it is new this year, leading to drive and system what is not very perfect, led to go a lot of detours, early know to buy Raspberry Pi 3 without so much tossFirst bought and then installed the Raspberry
Bought a Raspberry Pi zero W, thinking of using a common micro data line to achieve the SSH Raspberry Pi + network + Remote Desktop target, toss for a long time finally success, words not much to start the whole.This article mainly deals with how to connect to the Raspberry Pi Zero (w) using the data cable SSH and Remote Desktop, and the network is included with
How to Use QEMU to simulate Raspberry Pi
The following describes how to use QEMU to simulate Raspberry Pi. After using this method, the system can be tested without a Development Board.
Development Environment
The Host OS environment used for testing is Debian 7.2 Wheezy amd64.
Guest OS is the Debian Raspbian () after the Raspberry Pi is optimized ).

, because the USB to the serial port of the minicom to communicate, and no garbled, the transmission of all the correct data2. Arduino mega2560 can transmit data, but there is garbled, possibly because the mega2560 serial port has the relation.Since the module is good, I think of another test method, a module using a USB port to the PC, and the other directly to my Raspberry Pi on the UART interface. The result was very sad.Raspberry

Pi is an irrational number, and there is no precise formula to calculate the π value, and π can only be calculated using approximate algorithms.The internationally recognized PI values are calculated using the Monte Carlo method.Monte Carlo (Monte Carlo) method, also known as random sampling or Statistical test method.When the problem solved is the probability of an event, or the expected value of a random

I want to use PI computing in Delphi. Can I directly call a function?
Do I have to write a constant Pi = 3.141592653?
I don't know if there is a constant definition in math. Pas? I am not eager to install Delphi here...
