On the basis of the previous note, complete a simple ADC sampling experiment.The first step: preparation of knowledge1, first look at the Bb_black ADC pin position. Is the distribution of the analog input ports of the bb_black.There are three important messages to note on this chart:(1) Number of analog input ports: ARM chip A total of 8 ADC channels, the Bb_black is led out of 7 pins, ain0~6;(2) voltage range of analog input port: 0~1.8v;(3) Number o

chipset of the motherboard, you can also identify the appearance of the CPU slot on the motherboard. The socketa slots used by the AMD processor have 462 pins, which are in a large shape and have no support. The intel processor's socket478 slots have 478 pins, which are in a small shape, there is a bracket (figure) around ).　　　　2. Memory and motherboard combination:　　The importance of memory must have been

You can see the full picture by removing the heat sink or fan (figure ). If it is difficult to identify the chipset of the motherboard, you can also identify the appearance of the CPU slot

I. Summary Summarize the distribution and storage methods of FPGA pins in US us II. Ii. Pin Allocation Method In addition to qii software, you can select the "assignments-> pin" label (or click the button) to open the pin planner and assign the pin. The following two methods are available for Pin allocation. Method 1: Import assignments Step 1: Use notepad or similar software to create a TXT file (or CSV file) and write the pin distribu

:- "Output mixer" is connected to the "DAC" via the "hifi playback switch ". When there is no path name connecting widgets (e.g. A direct connection) WePass NULL for the path name. Interconnections are created with a call :- Snd_soc_dapm_connect_input (codec, sink, path, source ); Finally, snd_soc_dapm_new_widgets (codec) must be called after all widgets andInterconnections have been registered with the core. This causes the coreScan the codec and machine so that the internal dapm State matches

Original web site http://blog.csdn.net/jzj1993 This section describes how to identify the PIN numbers of an integrated circuit. Here we will briefly understand the specific functions of 40 pins of 51 single-chip microcomputer. Readers who have never been familiar with complex electronic components may feel very difficult, but they do not need to be afraid. 　　 Accordin

Abstract: To meet the needs of Linux to transplant the S3C2410 microprocessor system, the S3C2410 peripheral storage system is designed. In this paper, the addressing principle of S3C2410 is studied, and the entire process of its addressing to SDRAM is analyzed in detail based on the timing diagram of the chip. The control registers and pins related to the storage system design are introduced, and the hardware circuit connection diagram with flash and

the power switch on the monitor turned on? Is the power led on the monitor lit? when hand close to the monitor screen and slowly move whether there is a "hissing" sound, while the hands of the hair has been a feeling of suction, this check the display High-voltage circuit is working properly. 3. If it is determined that the display has been added, and there is high pressure, continue to check the data cable connectors and video card signal output interface is good contact? Is there any looseni

low. Writing low or high can not only be set to output but also to set the output level. Of course, if the kernel does not support or the kernel code is unwilling, there will be no such attribute, such as the kernel call Gpio_export (n,0), which means that the kernel is unwilling to modify the Gpio Port directional propertiesvalue represents the level of the Gpio pin, 0 (Low level) 1 (High level), if the GPIO is configured for output, this value is writable, remembering that any Non-zero value

Q: Some time ago when the CPU fan was removed, because the CPU and fan stuck, the hand to break apart. The result is that a row of pins in the CPU is crooked, and when the CPU pins are straightened, the pins with the notch diagonally are broken, but the computer that plugs into the CPU socket can also be lighted. My CPU is a 478-pin P4, I do not know if there is

In this tutorial, we will study the programming method of MSP430 MCU Gpio. This article also applies to the MSP430X2XX devices used on the Launchpad Development Board, such as msp430g2553, msp430g2231, etc. Most pins on the MSP430 microcontroller are grouped into up to 8 ports, P1 to P8. Each port is 8-bit wide and has 8 related I/O pins. These pins are mapped di

called the real jumper First, let's correct a conceptual question, in fact, the row of the motherboard that need to be wired pins are not called "jumpers", because they do not "to the function of jumpers." The real jumper is two/three root cuttings pin, there is a small "jumper" that should be called "jumper", it can play the role of hardware change settings, frequency, etc., and the chassis connected to those p
