An Isolated DAC Using PWM OutputArduino ' s (atmega328p) PWM outputs via Analogwrite can be conveniently turned to analog voltage levels through the use O F Simple RC filters.Since the PWM outputs is not a isolated, using them to drive other devices directly could is potentially dangerous.This is especially true if the target circuit uses a higher supply voltage.Fortunately, it's quite easy-to-isolate the PWM output using an optocoupler.The following

1. Lsb,least significant BitThe LSB is the weight of a bit at the lowest bit, and the ADC is a ruler, and the LSB is its smallest scale. lsb=vfs/(2^n), the VFS is full scale voltage,n is the resolution of the ADC (Resolution).2. Offset ErrorOffset error is often called Zero-scale error. Simply understood, for the ADC, the input analog signal, only offset (or overlay) offset error, in order to normal ad conversion, and for the DAC, the output of the an

When I tested the SQL Server 2014 memory database some time ago, I found that if the database size exceeds the configured maximum memory size, SQL Server encountered Error: 701. Error message: Error: 701, Severity: 17, State: 123. There is insufficient system memory in resource pool 'internal' to runthis query. At that time, I deleted the database and restarted it. In fact, when the memory is insufficient, DAC can still be connected. The following

1. DAC conversion trigger conditions. There are two trigger conditions. One is to write the value you want to convert to the dacn_chxdata register, provided that you need to enable the DAC first. Or write the value you want to convert to the corresponding part of the dacn_combdata register. The dacn_combdata register maps the values of dacn_ch0data and dacn_ch1data to help you trigger the output of both ch

A dedicated administrator connection is a special SQL Server server diagnostic connection that is used to connect to a server for server performance or error diagnosis in a normal or standard connection form that cannot connect to a SQL Server server. The DAC also supports secure encryption and only members of the sysadmin server role group have permission to use the DAC. By default, the

As early as you know, you can connect to SQL Server by using a dedicated administrator connection, but it has not been successfully connected. Seeing this again today, I want to try again.1. Enter ADMIN:GGG in the server name in the "Connect to
