Q: How to implement a single chipEthernetMicrocontroller?A: The trick is to connect the microcontroller and Ethernet Media to the Controller (MacAnd physical interface transceiver (Phy) Integrated into the same chip, which can remove many external components. This solution enables good matching between MAC and PHY, and reduces the number of pins and chip area. The Single-Chip Ethernet microcontroller also r

the program, you can read data from the serial port. We transmit the temperature information collected by the microcontroller from the serial port to the computer, as shown in figure. This completes the simplest serial communication program. You can see that it only needs to add a few lines of code, which is very simple. Part 2: The previous section describes how to write the simplest serial receiving program. The following describes the program c

Chapter 4 Architecture 1st Q:Q: What is the processor mode when executing the mov R0 and LR commands at the beginning of CPU stack initialization?A: The reset mode, that is, the management mode. 2nd Q:Q: How does 0xf0000001 obtain the number of 8 bitmap values in mov?A: shifts the right of a loop, that is, the number between 0 and 255 shifted to the left or the number of even digits shifted to the right, that is, the number is divided by 4, it is okay if it is an integer in the range of 0!A:

Apache Cassandra nosql databases. 5. node-red Node-red is based on node. js and describes itself as a "visualization tool for connecting to IOT ". It allows developers to use a browser-based flow editor to connect devices, servers, and API applications. It can run on Raspberry Pi, and more than 60 thousand modules can be used to expand its functions. Hardware 6. Arduino y ún The microcontroller combines ease of use based on the Arduino board with t

compatibility with existing arm solutions. Thumb-2 technology uses 31% less memory than pure 32-bit code, reducing system overhead. At the same time, it can provide 38% higher performance than the existing thumb-based solutions. The armv7 architecture also uses neon technology, which improves DSP and media processing capabilities by nearly four times and supports improved floating-point operations, meet the needs of the next generation of 3D graphics, game physical applications, and traditional

Recently, I am working on the low power consumption of the PIC microcontroller. So I set different I/O port States to test the power consumption. The current is measured using a series multimeter. the I/O port of the microcontroller is suspended, the entire system is not driven by peripherals, and the test uses the pic16f690 microcontroller. The idea is as fol

Let's see.Basically is the point to open, to the serial port to send data ' 1 ', point Open, to the serial port to send data ' 2 '. The next machine microcontroller inside will be the ' 1 ' and ' 2 ' to identify, remember Oh, this is the characters

slower BAUD rate (or a single 0xFF byte which only have the start bit low) and if it works. We had a problem using 115K2 baud rate where we microcontroller communicating with the RPi could hits 113636baud or 119047 Baud. 113636baud had the lowest error margin so we used it and TX from the RPi being received by the microcontroller worked fine . However when transmitting to the RPi is ever received. Changing

the loaded program no longer exist, here is called the jump is sometimes referred to as the run to the loaded program.3) boot loader is usually written in combination with a compilation and a C program, but the BIOS is often written in a compilation to save program space.Let's take a look at what the boot loader will do during the boot process. Before we discuss this, we need to understand what the difference between the processor of the embedded system and our computer processor is. For the pr

following example: Old Code: long factorial (int i) { if (i = = 0) return 1; Else return I * factorial (i-1); } New Code: static long factorial_table[] = {1, 1, 2, 6, +, 720 * * etc * *}; long factorial (int i) { return factorial_table[i]; } If the table is large and hard to write, write an init function that temporarily generates a table outside of the loop. (2), to find the remainder of the operation a=a%8; Can be changed to: a=a7; Note: bit operations need only a single instruction cycle to

format, eliminating the interference of byte order.Why can Java cross-platform? Because bytecode is run on a virtual machine, not the compiler. In other words, because the JVM can be installed across platforms, the corresponding Java bytecode can then be run on any platform. As long as the JVM's own code can run on the appropriate platform, that is, the JVM is viable, then Java programmers can take care not to think about where the program is written, but to run it on the virtual machine and th

The so-called signal (Singal), in my understanding, in fact, and microcontroller development in the same as the interruption, but it is not provided by the system hardware, but the software operating system support a reminder mechanism.The processing method after receiving the signal, generally consists of three kinds:(1) The first is similar to the interrupt handler function, and for the signal to be processed, the process specifies a handler functio
