range of 32GB~2TB. While the SDXC card still needs to wait for its price to fall further, the SD4.0 specification has begun to develop in tension, which is beyond the scope of this article. 2. SD Card driver
The SD card supports a total of three transmission modes: SPI mode, 1-bit SD mode, and 4-bit SD mode. All SD cards must support the older SPI/MMC mode, which supports a slow four-wire SPI interface, enabling many microcontrollers to read and write SD cards via the SPI or analog SPI interfac
, memory resources, codec algorithms, peripheral device interfaces, and so on a single platform. Most of the functions are solidified on the chip, and some special functions are modularized, the source code is provided to users, and users can perform secondary development based on different application needs. In addition, the SOC can also add video coprocessor and other video subsystems, video processing capabilities are further enhanced by features such as preview, zoom, optical processing, and

A design mode of Reduced Instruction Sets and computer CPU. It is short for hierarchical CED instruction set computing. In the early days, this CPU instruction set was characterized by a small number of commands, and each command was characterized by a standard character length, short execution time, and CPU implementation details that were visible to

These three concepts are confusing during USB development. For USB operations in real environments, endpoints, pipelines, and interfaces cannot be ignored. The relationship between these three concepts is 2-6-1;
The USB physical endpoint. In the NXP lpc2478 USB, there are up to 32 physical endpoints, each endpoint from 0 to 31 has a fixed transmission mode (I/out). In means that the hub sends data to the host
NXP Semiconductors n. V .) (NASDAQ: nxpi) recently launched the industry's first ultra-broadband Doherty power amplifier (470 to 806 MHz). The new product uses the ultra-broadband Doherty reference design of the blf884p and blf884ps architectures. The brand new 70 W DVB-T LDMOS is designed to use an over-Broadband Operating-in-house (patent pending) architecture that improves the efficiency of the Doherty topology for broadcast transmitters.

Q1: What is NFC?
NFC (near field communication) is a short-range wireless communication technology that uses the 13.56mhz band. Although the communication distance is only about 10cm, just like the non-contact IC Card Technology, you only need to touch it to exchange data between different electronic products.
Unlike non-contact IC cards, NFC supports bidirectional communication. Data can be read or written as long as NFC products and IC cards are supported. It can also communicate with othe

Many of my current active projects are using NXP's Kinetis Design Studio (KDS) V3.2.0 (I've published a lot of projects on GitHub). Now with the advent of the Mcuxpresso IDE (see "Mcuxpresso IDE: Unified Eclipse IDE for NXP ARM cortex-m microcontrollers"), I've migrated several KDS projects to Mcuxpresso. This article is about how to easily migrate KDS projects and run them in the Mcuxpresso IDE.OverviewThe Mcuxpresso IDE uses a newer Eclipse IDE (Neo

As we all know, the Charm clan itself is to do MP3, in fact, this sentence in yesterday's press conference, Bai Yongxiang again mentioned. And we know that 2 months ago the Phantom of the MX5 flagship machine does not support HiFi music, let a lot of kerosene to spit trough. Therefore, in order to reflect the domestic high-end brand image, the charm of the Pro 5 joined the HiFi 2.0, so this is worth affirming, and therefore very sure to tell you that the Phantom of the Pro 5 is to suppor
