mplab IDE and allows Debugging Using online simulators and online debugger. The default installation directory is c: \ mcc18. After the installation is complete, open the language tool mounting Settings dialog box. You can also see the interface shown in 4. When using mmc18 programming, you must add the connector script file (*. LKR) and header file (*. h) at the same time ). The connector script file mainly provides the storage space available for the connector and how to use the space, which

We learn MCS51 single-chip microcomputer and AVR MCU, or PIC microcontroller, or MSP430 MCU, whether it feels that he can become an engineer? I'm here to say what I think.We learn these single-chip computer, the first study of theoretical knowledge, this is generally the theoretical knowledge of books, such as the introduction of the development of single-chip microcomputer, the application of single-chip microcomputer, the principle of single-chip mi

Source: again out of a scheduler, small resources microcontroller is worth a useSelf-thought has the following characteristics:1) Super portability, CPU-independent, almost any CPU that supports C programming can be used! (This article only takes 51 single-chip microcomputer as an example, but can actually be transplanted arbitrarily)2) Small and small, the principle is very simple, a look will understand.3) province and province, can be said to the R

contrast, the MCS-51 microcontroller command system has a total of 111 commands. The introduction in this book is mainly aimed at the 8-Bit Microcontroller PIC16F877 of the mid-range Microchip Company, which has the on-chip (On-Chip) EEPROM data storage and flashProgramMemory, which can realize in-circuit debugging and In-circuit serial programming. With the help of the Economic online debugger (MPLAB-ICD)

In the learning of the microcontroller only really know what the C language is, it is to do ~ but the C language used to embed only its small part of the application, there are many places.We are not in the process of writing, many errors even if the compiler passed the results of our expectations, it is not difficult to find out where the wrong? I think that language can be called language, it is certainly a tool, a mutual communication between each

According to the analysis in Figure 2, the height of the Guide code is 4.5 ms, and the low level is 4.5 ms. WhenWhen this code is received, it indicates the beginning of a frame of data. The microcontroller can prepare to receive the following data. The address code consists of 8-bit binary codes, 256 in total. In the figure, the address co

In a recent project, I learned about the external Ram Extension of the AVR microcontroller, which is recorded here. In this paper, we use a single-chip microcomputer with a single-chip microcomputer as the testing platform and expanded 74hc573 (AHC series are used in the data section. However, I used the HC series to configure the fastest access speed under the 16 m crystal oscillator and did not find anything wrong, of course this is not a rigorous d

Next let's take a look at whether the above initialization function is available. We have written three functions as follows: Dm9000_init (), sendpacket (), and receivepacket () are saved and named dm9000.c. Now that we want to debug, when However, there must be outp

This article describes in detail how to migrate the NFC Reader library to the Kinetis k64f microcontroller. This article uses a real-world porting case to demonstrate the steps required to migrate the NFC Reader library to the sample target MCU. The purpose of this article is to serve as a guide for software developers to transplant the NFC Reader library into the MCU chosen by their design. NFC Reader Library Overview The NFC Reader Library is a se
