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 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

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,

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

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

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

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 );
