Today, the circuit diagram of SD card module, found that the operating voltage of SD card is 3.3V, so need to use voltage regulator chip to convert 5V power supply to 3.3V voltage, so a little bit about the voltage regulator chip data We choose the voltage regulator chip is asm1117-3.3, encapsulated as SOT-223 But in the drawing of the schematic diagram of the

This paper mainly discusses the STM32 of conventional chip capacity and the difference between large and small capacity of STM32 chip. The STM32 large capacity chip is a chip that includes up to 512K bytes of flash memory and 64K bytes of SRAM for large capacity. STM32 small capacity

Now there is no line from the product brand and the price of various, how to be in the confusion of the flowers are not blind, in fact, as long as you see the hardware chip behind each product, you can have a general selection basis, information from the network, but summed up together to facilitate their own or users have the time to reference.Wireless Protocol IE802.11 Family: Protocol release year/date Op. Standard band widt

Ⅰ , overviewRegarding the storage of the data, I think the programmer will basically use it, just to see where you store it. STM32 the inside of the chip FLASH can be programmed, which means that data can be stored. However, many do small application development of people do not take advantage of this feature, but instead of a separate EEPROM or FLASH, I think in some cases (small data, Not often changed) this is a huge waste of resources. about usin

Power consumption is a top priority for battery power supply systems. we know that a single-chip microcomputer has a power management register pcon, which has the lowest two. IDL and PD are used to set whether the single-chip microcomputer enters the idle mode and the power-down mode respectively.1. idle modeWhen the single-chip microcomputer enters idle mode, al

[Guidance] researchers found that when running software on a single core, ARM chips are more efficient than Intel core chips and are more suitable for applications in high-performance computing systems. On August 1, Beijing time, according to foreign media reports, researchers from the Barcelona super computing center published a paper saying that smartphone chips will one day replace x86 chips with higher prices and higher energy consumption, used in a supercomputer. In the history of high-pe

The debugging of the algorithm porting encryption chip contains 2 parts: Communication Debugging and Algorithm debugging. Before talking about the communication debugging skills, the next chapter will be the algorithm debugging problems in the analysis and summary, to help customers to complete the debugging smoothly.Frequently asked questions in algorithmic debugging:1. Do not build your own projectWhen porting the algorithm, the customer does not ne

Hello everyone, this is the use of a blog, this article is the ATSHA204A encryption chip configuration, mentioned above, atsha204a encryption chip internal ROM three areas, one is Config zone, one is slot zone, there is an OTP zone, This article not only explains Config zone configuration, but also explains the slot and OTP area configuration method, and unifies the official library to demonstrate the code.

Speaking of the 51 MCU clock first thought about 51 o'clock how to work. Micro-controller to work must have a "power", for 51 single-chip microcomputer, this "power" is the clock source. A 12MHz crystal oscillator is used as the clock source for general applications. Generally the first method is used more often. When the internal oscillation mode is selected, there are two small capacitors next to the crystal oscillator. These two capacitors are call

Ing means a one-to-one correspondence. Re- ing is the one-to-one relationship of re-allocation. We can regard the memory as a black box with the output and input ports. As shown in, the input is the address, and the output is the data stored on the corresponding address. Of course, this black box is made available by complicated semiconductor circuits. We do not care about the specific implementation method. The storage unit is generally byte. In this way, each byte storage unit corresponds to a
