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. Set the value of the pre-divider in the control register (adccon) t

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

+-0.08 °C. Encapsulation: To-92, metal can, SOIC-8, to-220. The lm35d used in this article is the to-92 encapsulation. Circuit connection The lm35d is powered by 5 V voltage on the Arduino uno board, and the signal output end is connected to the A0 pin. Simple voltage reading and conversion The conversion is implemented using the Arduino ADC function. The relationship between the voltage and the ad sample value is as follows: Among them, vin is the

Measure the ambient temperature around the chip. The output voltage of the temperature sensor is proportional to the temperature. The obtained temperature is measured by ADC. Inside the chip, the temperature sensor is connected to the ch16 of adc1. If you do not use a sensor, you can set it to the powerdown mode to save power. Main features: Temperature measurement range:-45 ~ + 125 degrees Celsius Temperature Measurement Accuracy: ± 1. 5 degr

First Glimpse of ZigBeeTo add a smoke sensor module to the ZigBee network, a cc2530 ADC is required to sample the analog signal output from the sensor. The following is a procedure for implementing an external voltage acquisition using an ADC of the CC2530.The following is the configuration of the ADC:1#include 2#include"adc.h"3#include"uart.h"4#include 5#include

Today's wireless users have no end-to-end requirements for higher capacity, faster access speeds, and higher data throughput capabilities, leading to the increasing radio signal bandwidth of cell base stations. As far as the network is concerned, brutal competition and declining profits have forced base station manufacturers to gradually adopt trade methods similar to PCs. This method uses a single architecture that can be applied to multiple network technologies and provides a general platform

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

In Adccon, the last 0 bits and 1 bits are mutually exclusive.If the 1-bit option is 1, the 0-bit value is not valid.The 0-bit value is valid if the 1-bit option is 0.When 1 bits of 1 are selected: This is the application layer of the program#if adstart==0void Niuniu (void){Uart_init ();Adc_init ();Beeper_init ();Adc_read ();while (1){Itoa (Adc_read ());if (Adc_read () > 2500){Beeper_on ();}Else{Beeper_off ();}Delay (10000);}}#endifNote here that the while loop must have Adc_read () above it, and

few microcontrollers include a DAC. Although you can easily find a inexpensive DAC to control from your microcontroller, you can use, unused peripherals inste Ad of adding parts. Fortunately, you can convert a microcontroller ' s ADC channel along with a GPIO (general-purpose input/output) pin to a D AC. You can make a DAC by charging a capacitor to an analog level by driving it high. You can also discharge the capacitor by driving it's voltage by tri
