How to set the chip to transmit mode (NRF24L01 as an example)
For the chip that just touched NRF24L01, it must be very strange. It feels amazing. I happened to see a friend on the Internet asking how to set the chip to launch mode. Let me share it with you here:
This needs to be set in the program, let's take a look at the NRF24L01 configuration register:
As shown in the above table, the configuration register address is 0x00, which is a byte, the highest is 0 by default; MASK_RX_DR is the role of setting IRQ. If it is equal to 1, the IRQ pin will not be used. Otherwise it is used to generate a high and low pulse. When RX_RD generates an interrupt, IRQ is low and it is used for reception. When MASK_TX_DS is 1, the IRQ pin is not used. Otherwise, when the data is transmitted, TX_DS will generate a The interrupt causes the IRQ pin to jump low and it is used for transmission. When MASK_MAX_RT is 1, the IRQ pin is not used. Otherwise, when the number of transmissions or receptions reaches the setting, MAX_RT will generate an interrupt to make IRQ. The pin jumps to your level; EN_CRC is generally 1, which is to start the CRC check; CRCO is to set the CRC mode, when it is 0, start the 8-bit CRC check, otherwise start the 16-bit CRC check; PWP_UP it is set NRF24L01 working mode, when it is 1, it is powered on, otherwise it is power-down, its role is to save power; PRIM_RX it is set NRF24L01 is working in transmit or receive mode, when equal to 1, then In receive mode, otherwise in transmit mode.
Ok, the above has been analyzed very clearly, now you should know how to set up the NRF24L01 wireless module for the launch mode! As long as you set PRIM_RX to 0, you can enable it in the transmit mode! Others can be activated according to your own situation!
Bitcoin mining equipment is mainly highly specialized ASIC mill , The maximum computing power of a single miner is 110T/s( Ant S19Pro mill ), The scale of computing power of the whole network is 120EH/s above . Ethereum's mining equipment is mainly graphics card mining machine , Professional ASIC Mining machines are very few , On the one hand, it is because of the of Ethereum mining algorithm [ resist ASIC sex " Improved R & D efficiency ASIC The threshold of the miner , So how much do you know about the mainstream Ethereum mining machine ?
Ethereum mining algorithm has higher requirements for memory , The purpose of this design limits ASIC The use of chips in Ethereum mining . From the results , Most Ethereum mining machines are graphics card machines , This reflects the application of Ethereum mining algorithm ASIC Success on . From the absolute value of computational power scale , The computing power of Ethereum is about 200TH/s, The computing power of bitcoin is about 120EH/s, The latter is close to the former 60 ten thousandfold .
ASIC Mining machines have high computing power , Large power consumption , Like the latest ant S19Pro mill , Rated power consumption is 3250W, Need to consume... Every day 78 Degree electricity , According to the current currency price and 0.23 The electricity price in wet season is RMB , The proportion of electricity charge is 30.68%. Other older bitcoins ASIC mill , Like ants T17 series , The proportion of electricity charges generally exceeds 50%. by comparison , The power consumption of the graphics card miner is low , The proportion of electricity is also low . such as 5600XT8 Graphics card miner of card .
Ant S19-95T It adopts aluminum alloy profile electromechanical integrated design , Parallel four fan structure . According to the measured data , In line with and better than the official data .S19 The series is provided by TSMC 7nm chip , A new generation of customized chips with perfect whole machine architecture and high conversion rate APW12 Power Supply , Reduce power loss during conversion , Use more energy-saving , Greatly shorten the return cycle of the miner . In addition, the newly upgraded mining machine operation interface is also more humanized , Real time computing power . The average computing power and the operation of each chip are clear at a glance .
Shenma mining machine M30S-86T/88T/90T, Bit micro 2020 Launched in 2013 M30S Series of new mining machines , Announced that it would M30S The series is expanded to three 3X product . stay 3X In the new standard , Bit micro promises a one-year warranty for its series of products . This series of mining machines are provided by Samsung 8nm chip , Among them, god horse M30S series , The power consumption is 38J/T, Provide higher computing power , Lower power consumption and high stability.
