exchange and digital signal processing. • Supports repetitive operations and avoids excessive time spent in cyclic operations.• Rich on-chip memory and external expansion memory interface. • Provide multiple serial or parallel i / o interface and special i / o interface ( etc ) Because the MCU and DSP have their own characteristics , so they have different fields of application. General microcontroller is often used in some simple contr

can be used to display a character, each bit has a point spacing between the interval, there is a gap between each line, play the role of character spacing and line spacing.3. Temperature setting Module:The tactile switch is an electronic switch that, when used, can be switched on by gently pressing the switch button, and when the hand is loosened, the switch is disconnected. Use 3 switches, respectively, function conversion, set +, set-, to complete all the set operation.4. Temperature control

I'm with Arduino, and why write this series of articlesArduino has been on fire for years, and it's not a new technology. If someone is not clear about what Arduino is, I'm sorry, please search by yourself, open any Wikipedia introduction or a fan of the series of articles, people introduced more than I know more comprehensive. I'm afraid I don't have to repeat it here.The first contact with Arduino was in 2008, then I know nothing about embedded development, just started to learn MCU, that is,

GPIO IntroductionGpio is used for the transmission of data by single-chip microcomputer and external devices.When the MCU Gpio is set to output, the MCU can output arbitrary data to gpio, and when the Gpio is set to the input microcontroller can read other devices and transmit to gpio data.STM8 microcontroller each port has 8 feet, each pin, can be independently programmed for digital input or digital outpu

Previously just learned single-chip computer, after a set of programming, can achieve a lot of different functions, at that time, it is felt that single-chip microcomputer is really powerful. Later came into contact with DSP, found that DSP processing digital in communication, more convenient. So I was curious to ask myself, DSP and microcontroller, what is the differenceSee a forum on the DSP and the difference between the single-chip post, after car

The 40 pins of a microcontroller can be divided into 4 categories: power , clock , control , and I/O pins .1. Power supply:⑴VCC-Chip power supply, connect to the + +;⑵vss-ground end;2. Clock:XTAL1, XTAL2-crystal oscillator circuit inverting input and output terminals. 3. Control lines: control lines Total 4, ⑴ale/prog: Address latch allow/on-chip EPROM programming pulse ①ale function: Used to latch a low 8-bit address sent by P0 Port

Development environment ConfigurationInstallation of IARfirst of all, I suggest you download cracked version, so do not go to their own to crack, even if not cracked version, there are a lot of cracked tutorials on the web, and then the next step, the following is the installation interface:CH340 (USB to serial) driver installationWhy to press this thing, because the microcontroller and the computer is connected through

for external expansion memory. The interior is also integrated with USB2. 0 device ports, as well as rich on-chip peripheral resources, powerful. The at9lsam7x256 reset controller can manage the power-up sequence of the chip and the entire system. The microcontroller has an embedded 10/100 MB/s Ethernet (Ethernet) MAC, CAN, full speed (MB/s) USB2. 0, designed for a wide range of networked real-time embedded systems, its performance is stable, powerfu

electronic design, some maker prefers a microcontroller platform, such as the fiery Arduino. But for some of the more complex projects, the 8-bit microcontroller is a bit stretched. For example, a 8-bit microcontroller can barely handle audio with low sample rates, but there's really nothing to do with video processing. However, with the booming of embedded syst
