A powerful virtual simulation platform can be built using Proteus and other programming software. Simulation

Recently, when debugging a board, it was found that the network port cannot be pinged when the board is restarted after power loss. It uses a 2041 film. When locating the problem, it is found that the serDes register Initialization is incorrect. After the first operation, the err bit is 1 and the done bit is 0. After the CPU is reset without power loss, the err bit becomes 0, if the done bit is changed to 1, Ping is normal. According to the symptom analysis, we first eliminate the problem of the

CounterFrom a routine of life to see: a water basin under the faucet, the water hose is not tightly closed, drip drops into the basin. Water droplets continue to fall, the capacity of the basin is limited, and after a period of time, it will gradually become full. So what is the size of the counter in a single chip microcomputer? 8031 single-chip microcomputer has two counters, called T0 and T1, respectivel

A chip from the birth of demand to the final chip packaging success, need to go through a very long process. If it's some kind of non-programmable chip,Compared to the new Isa, the two types of chips corresponding to the software workload, is not at an order of magnitude. Non-programmable chip, does not require the ISA

SCM Serial Port Communication has 4 different ways:Mode 0: Shift register Input/Output mode: Baud rate: FOSC/12;Mode 1:10-bit UART (Universal Asynchronous Interface Circuit), the format of a frame of data is: 1-bit start bit, 8 bit data bit, 1 bit stop bit. Its baud rate is variable (by formula):Mode 2 and Mode 3: Both methods are composed of 11-bit UART, one frame data format: 1 bit start bit, 9 bit data bit, 1 bit stop bit.Where the baud rate of Mode 2 is fixed to: FOSC/32,FOSC/64, determined

Open market: Not including Xiaomi, Le Vision and other major brands closed-loop ecosystem market.This year, the four-core network player with Allwinner a31s alone lead. British Fick to the absolute advantage of the first of the White brand Company. Only with the passage of time, the a31s not adapt to the mainstream market. Because the chip does not have h265 hardware, 4k hard solution, plus a31s itself price is too high, the whole ambition almost not

This article tags: Nordic chip macosx I tried to compile the Nordic Nrf5x Series project with GCC under Mac OSX, but found that the compiled hex could not be burned, so it was down for a while. Now we have to pick it up and solve the problem.The following are the compile steps: Nordic official website Download SDK:NRF51822SDK The chip of the NRF5X series running ble is divided in

Group-Phison main control chip Group Phison main control chip is used most, because it is the best compatibility, the highest rate of production success (99%), and read and write speed is almost the fastest (horror of writing 16 read 31), so it is rookie production supplies. But Phison has a disadvantage, that is, it does not support the output USB-CD and USB-HDD coexist at the same time, which makes peopl

Each MySQL database server is equipped with a SQL chip, this is the Kickfire company began to look at the Data Warehouse market a vision. Kickfire launched the Kickfire Database Appliance beta, which incorporates new SQL chips on April 14. The company says the SQL chip can extract data directly from memory without the need for registers or caches, thus easing the I/O bottleneck that causes slow data querie

Uboot's Gpio is quite simple, it is a three-layer structure. Respectively: 1, the top layer interface layer, which only defines a common interface, is not responsible for implementation, implementation is based on specific chip to achieve. 2, the middle interface implementation layer, with the specific board of the GPIO to achieve the top layer interface 3, the underlying specific chip GPIO implementation l

example: The crystal oscillator frequency is 12MHZ, then the clock cycle tosc= (1/12us). 2.3, Machine cycle: The basic operating cycle of single-chip microcomputer. In the computer, in order to facilitate management, the implementation of an instruction is often divided into several stages, each phase of the completion of a work. For example, taking instructions, memory reads, Memory writes, and so on, each of these tasks is called a basic operation.

The chip has been crushed.Today the download line of the GND download line from the chip seat off, may be too tight, the line is broken. And then re-do, the result is too hard, the chip block pin broken. Now listen to a digital group of users of the proposal welding a copper wire up, it seems that can be used, but the seat to the hot bad look. Because it is not f

Work for 7 months, the microcontroller programming also began to slowly familiar with, always know that single-chip microcomputer is the timer, state machine, interrupt these things combine efficiency is quite high, but since the development of GPF this chip, I found another kind of microcontroller development skills, master please bypass.We all know that in the program, the delay will affect the real-time

The core of single chip microcomputer temperature control systemBy the 895X series microcontroller to drive the 18B20 temperature sensor module, by writing the C language code, to achieve the control of the module driver, and constantly receive read 18b20 sent over the temperature signal. The transmitted high and low bits are converted into 10 binary numbers by processing the personal code to display in the LCD.This single-

There are two methods in general: one is to writeProgramWhen the test mode is added, another way is to send the HCI command through the PC to enter. The method to add the test mode to the underlying program is to add the connectionenterdutmod call to the program. Sending commands via PC is a little more complicated. The specific steps are as follows: Use the pstool tool to enable the Bluetooth chip through SPI or UART, modify VM disable it
