bitcoin mining machine is the computer used to earn bitcoin
mining software is the algorithm of bitcoin
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
extended data:
bitcoin has the following six characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Worldwide circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
(12:00 on December 12) zhongbencong mining was officially launched
bitcoin founder Nakamoto's second coin, BTCs, is ready for mining. Everyone hurry to get on the bus. BTCs coins are issued with a total of 21 million pieces, including block height, block time, total network computing power and hash value; Authentication is simple and face recognition is easy. Free mobile mining; Missed btc-10071; Don't miss bitcoin BTCs any more, now sign up for space mining

Mining needs high-end graphics card, just to solve the problem of high-end graphics card is not easy to sell
Just download a gpu360 miner
if you are a tribe, you can go to orgrima to find a guard and a mining trainer, who will also teach you most of the skills of smelting ore
by the way, there is also the team "black wing nest" in the 1960s, namely BWL. At the penultimate boss corner, there is a goblin monster who is guarded by two monster elites. He dropped a tutorial to teach you how to smelt the magic ingot of orange quality
there are also seven masters of "Blackstone abyss". One of them will teach you how to smelt black iron ingots; The specific methods are as follows:
before going to the Blackstone abyss, prepare 20 gold ingots, 10 real silver ingots and 2 rubies. This is the tuition fee for learning to smelt black iron ore
enter the and come to the grave of the summoner, which is commonly known as the seven sages. Don't worry about talking to the NPC at the top, just say it and fight! First find the NPC on the right, which is the one with a basin beside him. Click the basin to put in the materials you have prepared. Then talk to NPC and you will learn how to smelt black iron
and "Sunwell highland", the little monster in the of the 70 machine team, will drop a tutorial to teach you how to smelt krypton ingots
I hope my answer can help you!
1. Open stm32cubemx and select the corresponding chip< The chip in this paper is stm32f207vct6, after selection:
2, configure RCC clock, ETH, PA8 and enable LwIP
as the hardware of the development board here is RMII mode, eth-rmii is selected. If you have a development board in MII mode, please refer to the configuration method of MII. This is only for RMII
RCC selects an external clock source and checks mco1. The software will automatically configure PA8 to mco1 mode. This pin is very important for RMII mode and is used to provide 50MHz clock for PHY chip
enable LwIP
3. The configuration of the clock tree must ensure that the mco1 output is 50MHz. If the frequency is not correct, the PHY chip will not work
here, because the chip is 207vct6, in order to make the mco1 output 50MHz, some adjustments of PLL frequency doubling parameters are made, as follows: (comrades can flexibly configure according to their own chip, but they need to ensure that the mco1 output is 50MHz)
4. Parameter settings of eth, LwIP and RCC
at this point, the more important thing is in the front, but there is still one thing to pay attention to, that is, the output speed of PA8 pin, which failed several times because this pin did not pay attention to
the subsequent parameter settings can be set according to the comrades' own needs, and the settings are given here for reference
the ETH parameter remains the default, but interrupt is checked once
LwIP parameters are set as follows: (because UDP server is configured and IP is allocated statically)
5. Generate the project and make the final function modification
Add UDP server initialization, port binding and other related functions to the generated project
here, the UDP server file in the previous official routine is directly added, as follows:
after that, the UDP server file is added
C file is added to the user program, and UDP is added to the main function
H header file
as follows: (the specific content of the UDP file is given later)
6. Several functions need to be added to the main function. Here, we will not explain the function and implementation principle, but only add them.
