1. Hello, cbyea500, the top in APM series< But as an open source flight control system, it can also be programmed by itself
performance is certainly enough for general flight control. In fact, performance is also related to your ability to write algorithms

for details, you can go to the relevant forums and ask< BTW: are you Michael Dou Bi?

2. Try changing a computer, a USB interface, and a data cable.
I know so much. I hope I can help you. If I can't, I can only try changing an MP3

3. Let's not talk about the advantages of blockchain public welfare. Just imagine how public welfare and charity organizations manage donations without a good supervision mechanism. Many people's first reaction should be that donations can't be traced and information is not transparent
blockchain technology + public welfare does not need third-party supervision, which reces the management cost. Secondly, donations can be managed by directly recording transaction data in the blockchain. Zhongan's firepile public welfare with blockchain technology is in this form
I can't be sure, but I have solved those uncertain problems before.

4. Tencent is the first to lead the blockchain in security, recording the whole process of donation material demand, supply, transportation and many other links on the chain for certificate storage, ensuring safety and compliance, and supporting the 100 million level business data on the chain efficiently.

5. Open and transparent information and traceability of funds have always been the goals of public welfare and charity. Blockchain can do just that. It can not only track and record all the information, but also ensure that the information is traceable and authentic. As for the successful cases, it seems that there are not many now. After all, it is an emerging technology, and it will certainly get strong support and application in the future.

6. Charity is a big topic. Here is a detailed introction of blockchain technology and how to help people in difficult areas to receive better help
whether it's the government or the public welfare organizations, charity is particularly important for people in difficult areas. However, we often think about whether the relevant funds have been allocated to people and where the money has been spent?, Where is the money spent? All these problems are worthy of our consideration
blockchain technology can give charity related funds & quot; Traceability & quot; Develop a charity based app to Digitally encrypt every charity fund or related materials (using the internationally recognized sha256 or China's encryption algorithm SN2)
the data structure of funds and materials uses Merkle tree to store the material data, ensuring that any changed data will automatically become invalid
the applicant and issuer who use asymmetric digital signature, The verifier and the secret key management of "public key" and "private key" can effectively record the processing data of a payment. If the payment is improperly processed or someone wants to query it, it will be very clear.

7. In 1999, RMB 100 belongs to the fifth set of banknotes. It was issued on October 1, 1999, the national day. Later, it was found that the word yuan was missing. The 2005 version was issued on August 31, 2005. Due to the large size of the economy at that time, the large face value, the large circulation, the large survival volume and the low price. A total of 402 titles were issued, the first FA was issued, and the supplementary titles were ah, AI, AJ, UG, uh, Xu, XW, XX, XY, XZ, UI, UJ, Hu, HW, HX, hy, Hz, yn and yo, which need to be judged from the number of titles, belt colors, numbers and serial numbers
first, judge the value of 100 yuan in 1999 from the number of FA. The price of 100 yuan in 1999 of FA is more than 150 yuan, and the smaller the number is, the more valuable it is. Similar to fa00000001, the new 1999 version of 1000 yuan is more than 50000 yuan. You need to consult the price of the day at any time according to the number and the market, The price of the 100 yuan note of the supplement number crown hu1999 is 2500 yuan, the 100 yuan note of the supplement number crown hx1999 is 2500 yuan, the 100 yuan note of the supplement number crown xu99 is 1000 yuan, the 100 yuan note of the supplement number crown uh1999 is 900 yuan, the 100 yuan note of the supplement number crown qn99 is 950 yuan, and the 100 yuan note of the supplement number crown yo99 is 500 yuan, The price of ah is 450 yuan in 1999, 260 yuan in AI, 280 yuan in AJ, 190 yuan in UG, 280 yuan in UI, 300 yuan in UJ, 240 yuan in HW, 300 yuan in hy and 120 yuan in Hz, In 1999, the price of XW crown was 240 yuan, XX crown 99 version was 240 yuan, XY crown 99 version was 240 yuan, and XZ crown was 240 yuan.

Second, judging from the color of the belt, the price of belt 99 version was 100 yuan, which was higher in the early stage. In 1999, the price of 100 yuan whole knife was about 13000 yuan, In 1999, the price of the white belt was 100 yuan, and the price of the whole knife was about 11500 yuan. F-crown, e-crown, c-crown, d-crown, g-crown, e-crown, c-crown, d-crown, h-crown, i-crown, j-crown, p-crown, q-crown, r-crown, s-crown, t-crown, u-crown, w-crown, x-crown, y-crown, z-crown, a-crown, b-crown, h-crown, i-crown, j-crown, p-crown, q-crown, r-crown, s-crown, t-crown, u-crown, others are RMB 100 yuan for 99 edition of white belt.

8. Recently, the concept of blockchain has been very popular. Like the Internet in the 1990s, it promises to completely change our whole life, whether professional or personal. Just as the Internet spawned thousands of new companies in the early days, blockchain is now in a similar situation
as the backbone of emerging technologies, blockchain is not only used in the field of virtual currency, but also in other fields such as finance, medical care, intellectual property certification, etc. a large number of excellent enterprises have emerged at home and abroad to explore or enter the blockchain instry. Microsoft, IBM, Tencent, Ali, JP Morgan, Netease and Xiaomi have all laid out blockchain, and blockchain will blossom in many fields in the past two years
it can be seen that blockchain technology is developing rapidly in the world. Perhaps in the next few years, blockchain related technologies will be applied to the field of intelligence and notarization, including identity information authentication, notarization, arbitration, audit, e-mail, personal visa, ticketing information and so on. The application scope can cover the whole society, and blockchain technology is likely to become the lowest level protocol of Internet of things.
