Previously, I wrote an article about counters that do not need to be registered.ArticleIn addition to the total number of visits to the blog, I also want to know the access volume of each page, as some counters need to increase the number of clicks on a single page. We still use the same count, so we need to write a small JavascriptProgramGenerate an id based on the blog URL as the Count ID. As long as the

Basic usageImport PybADC = Pyb. ADC (Pin (' Y11 ')) # Create an analog object from a PINADC = Pyb. ADC (Pyb. PIN.BOARD.Y11)val = Adc.read () # read an analog valueADC = Pyb. Adcall (resolution) # Creale an Adcall objectval = Adc.read_channel (channel) # Read the given channelval = adc.read_core_temp () # Read MCU temperatureval = Adc.read_core_vbat () # Read MCU Vbatval = Adc.read_core_vref () # Read MCU Vr

The book connects to the text and starts to toss about the DMA transmission of the ADC. Because everyone is talking about DMA, even the st example uses DMA. The data collected by the ADC is stored in a fixed register. When multiple channels are sampled in the conventional sampling method, DMA can be used to avoid data loss. When the DMA function of the ADC is e

1. stm32f103 ADC In this example, the pa1 pin of the stm32f103 chip is used to test the analog input voltage value. Article 31st, pin definition: We know that pa1 uses adc1 Channel 1. The Clock Tree is shown in the following figure: Adc1 can be divided into 2, 4, 6, and 8, and the ADC input clock cannot exceed 14 MHz (see the stm32 reference manual rm0008 chapter 11th

Read the pin voltage value from the ADC with the STM32, how to convert the data read back to the value of V???V (ADC) = Value (ADC) * V (ref)/4096(The Stm32 ADC is 12 bits, so the maximum ad Word is 4096) where V (ADC) is the calculated voltage value, and value (

Soon, I entered the fourth class of ADC-driven learning. After the first three lessons, I believe that everyone, like me, feels a little bit about the driver. Based on this, I quickly master the general framework of the ADC Driver. This course focuses on mutex semaphores, memory ing, and other issues. For more internal details, also, please read the official comments. The code is pasted as follows: # Inclu

the 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 18 channels and can measure 16 external and 2 internal signal sources. The input clock of the ADC must not exceed 14MHZ, which is generated by the PCLK2 frequency divider. if the analog voltage converted by the ADC is below the low threshold or higher than the high threshold,

The registers of the ADC are read,int Adc_read (void){int result;#if adstart==0result = ADC. adcdat00x3ff;while (!) ( Adc. adccon (0x1{}#elif adstart==1while (!) ( Adc. adccon (0x1{}result = ADC. adcdat00x3ff;#endifreturn 3300/0x3ff*result;}#endif****************************

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 over

ZigBee Tour (vi): Several important CC2430 basic experiments--ADC Single sampling first, the connecting link In wireless sensor networks, it is important to convert the analog value of the sensor to digital to facilitate transmission and processing. ADC (Analog-to-digital Converter) is used to accomplish this conversion. In the previous section, we introduced the serial communication between CC2430 and PC

The ADC in stm32x microcontrollers uses the SAR (successive approximation register) principle,By which the conversion are performed in several steps.The number of conversion steps is equal to the number of bits in the ADC converter.Each step was driven by the ADC clock.Each ADC is clock produces one bit from the result

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 );

#include "stm32_lib/inc/stm32f0xx_rcc.h" #include "stm32_lib/inc/stm32f0xx_adc.h" #include "stm32_lib/inc/stm32f0xx _gpio.h "int main (void) {//Clock configuration rcc_ahbperiphclockcmd (Rcc_ahbperiph_gpioa, ENABLE); Rcc_apb2periphclockcmd (rcc_apb2periph_adc1,enable); ADC IO configuration, where the PA0 port is defined as the ADC ports Gpio_inittypedef PORT_ADC; PORT_ADC. Gpio_pin=gpio_pin_0; PORT_ADC
