2.1 SPICommunication Interface Design
In the system design, two external chips apply the SPI interface methods: AD7705 and AD421. The single chip microcomputer and the two peripheral chips constitute an SPI bus system. The NSS end of the single chip microcomputer is suspended and the on-Chip pull resistance is set to a high level connection, because AD421 is a 4 ~ 20mA output of the digital-t
Assembly arithmetic operation commands8086 of arithmetic operation commands can perform addition, subtraction, multiplication, and Division operations on binary or decimal (BCD code) numbers, the data format of an operand can be 8-bit or 16-bit unsigned or signed. An immediate number is not allowed for single-operand commands. for dual-operand commands, only source operations can use immediate numbers. One of the two operands must be in a register.

integrated environment and infrared to digital converter with a built-in infrared LED driver and I2C interface (compatible with SMBus ). The device provides ambient light sensing to achieve stable backlight/display brightness control. Infrared sensing with interrupt function can achieve close estimation. (Proximity sensing is an important feature. More details will be discussed below)
For ambient light sensing, the ADC inside the sensor is designed u
its control over external devices.Dry-reed Relay refers to the reed relays, which are compared with the general relays, and their switching speed and life are greatly improved. The use of the relay is very simple, only the level control of its pin to complete the control of the relay. After entering the source directory, enter in the terminal:CD "Grove-relay"sudo python relay.pyThe Rasbperry Pi will control the relay to switch on and off every 0.5 seconds.9.

Many netizens have asked about the main difference between CCD and CMOS. For the time being, let's take a look at the two different types of image photosensitive elements with the same function through a simple comparison.Both CCD and CMOS basically convert light to electricity using the silicon photodiode. The principle of this conversion is similar to the "Solar Cell" effect of the "Solar Energy" electronic computer in your hands. The stronger the light, the stronger the power. On the contrary
1. Add
ADD OPRD1 OPRD2
Operation: (OPRD1)
Impact flag:
OF: if the two operands have the same symbol and the result symbol is opposite, overflow OF = 1; otherwise, OF = 0
(For example, if two positive numbers add a negative number, or two negative numbers add a positive number, the addition of the opposite two numbers does not overflow)
CF: indicates the overflow of the unsigned number (carry)

The recent project is doing background check, and the latter is basically the use of regular expression verification, this article to do some rough summary.1, string length:. {1,10}, note that there is a point before {}, which means matching all. ' {} ' must be a capturing group before, so if there are additional filtering requirements and the limit length is the last plus {} in the total capturing group to limit the length.2.

frequency point you want to adjust;Gain, gain-the parameter used to adjust the gain or attenuation on the F value you set; quantize, bandwidth ratio-this parameter is used to set the "width" of the frequency band for gain or attenuation. The smaller the Q value, the wider the processing frequency. Application Description: There are two common types of music balancer: graphic equalizer and parametric equalizer

Assemble to ShardAlthough you can delete a shard, there is no formal path to remove the Shard from the collection. This is done by first exporting the data with the Mongodump command and then using Mongorestore to recover the data.Vi. backing up a shard collectionTo back up a shard cluster is the need to configure data and a copy of each shard data, one way to use the Monodum
