I. background: Although mod_fifo and mod_callcenter can be used as call center applications, it is difficult to customize these two modules in the application, here I use Lua to implement the 5-way Customer Service (1000-1004), a call center number: 9958 ADC implementation solution, which is recorded here. Ii. flowchart: Iii. Specific settings: 1. Add/usr/local/freeswitch/CONF/autoload_confilgs/modules. conf. XML to the mod_lua module, which is loade

EFM32 currently supports two ADC modes: single mode and Scan mode. Single mode is a Single-channel conversion mode, while Scan is a multi-channel conversion mode. In Single mode, because it is a Single-channel application, you will encounter the problem of how to switch the ADC channel. The following is a routine for switching the ADC channel in

EmbeddedLinux Bare Metal Development (14)--ADC First,Introduction to AD conversion ad conversions are analog -to-digital conversions , is to convert analog signals into digital signals. A/D converters are used to convert analog quantities into digital quantities through a certain circuit. Analog can be voltage, current and other electrical signals, can also be pressure, temperature, humidity, displacement, sound and other non-electrical signals. Befo

Generally, the ADC must be used together with the DMA. Here, the ADC application is simply configured with the library to continuously scan the ADC. First, configure the clock of gpio and ADC: Adc_inittypedef adc_initstructure;Gpio_inittypedef gpio_initstructure; Rcc_apb2periphclockcmd (rcc_apb2periph_adc1, enable );

Normal through the file system access to the value of Ain serial port, you can use Fread and other file IO read/sys/bus/iio/devices/iio:device0/in_voltage*_raw content. But this requires high frequency access to the ADC is very inefficient, the data needs to be copied from the disk to the kernel process space, and then copied to the user process space, consuming unnecessary resources. This problem can be solved by memory innuendo, Mmap can realize the

The figure shows that the analog ADC has two functions: Touch Screen and general ADC. Int_tc and int_adc can be generated respectively. The ADC module has a total of eight channels for analog signal input, ain0, ain1, ain2, ain3, ym, YP, XM, and XP are selected through an 8-way analog switch MUX.

There are projects that need to use Silabs's c8051f850. In fact, the most important is to fancy the price, as well as its working temperature. So we need to start learning this film. The simplest ADC routines are as follows:Initializes the system clock, initializes the IO, and so on. The P1.0 is led output and the P1.2 is the ADC input. The ADC uses VDD and GND a

Each ADC module of stm32 can switch to different input channels and perform conversion through an internal analog multi-channel switch. Stm32 is particularly added to multiple group conversion modes. After the program is configured, It can automatically sample and convert multiple analog channels one by one. There are two ways to divide the conversion group: rule Channel group and injection Channel group. Generally, up to 16 channels can be arranged

The entire concept of Software Defined Network (SDN) is about abstracting hardware to enable new types of network streams. Although many early discussions on SDN are concentrated on routers and switches, SDN does not stop here. SDN has many functions, including helping WCO and application delivery controller (ADC) businesses. Recently, network vendor Riverbed has joined the web content optimization market with its Stingray product series, which also i
