This article refers to how stack allocation is seen in the puppypuppy2005 "Keilc51" http://puppypuppy2005.blog.163.com/blog/static/52048156200911741010340/ KEILC is a very good C51 compiler, probably the best C51 compiler, offering a variety of optimization modes, optimized for variables and an excellent address arrangement. This is one of the benefits of writing code in C, if you write in a sink, it takes a lot of effort to arrange the memory physical address for each variable, but also to

Recently contact NRF51822, get started or relatively easy. Today found wonderful problem: Download an official Flashwrite program, not only the program is not properly executed, NRF51822 also become brick, Keil MDK can not identify the chip, NRFGO can not recognize the chip. Without knowing, I burned another board, and still succeeded in changing bricks ... (1) Keil MDK can not recognize the chip, res

Single Chip Microcomputer 1.Create a Keil C Project for this project and create the src directory to store the source files. 2.Read the uip-1.0/Unix/Main. C, understand the UIP's main loop code architecture, and put main. c uip_arch.h under the src directory. 3.Follow the uip-1.0/Unix/tapdev. C to write the NIC driver, and the specific hardware. This step is a little time-consuming, but fortunately most of the NIC chip drivers have code for reference

To debug arm, you must follow the debugging interface protocol of arm. JTAG is one of them. During simulation, IAR, Keil, ads, and so on all have a common debugging interface. RDI is one of them. How can we complete RDI --> arm debugging protocol (JTAG)? There are two methods: 1. write a service program on the computer, parse the rdi commands in iar, Keil, and ads into the relevant JTAG protocol, and then u

No cortex-m SW Device found solution16.07.14today's work, encountered a problem: using the jlink SW download mode, always show No cortex-m SW device found. Drivers are installed, before using 20pin jtack download mode are good, changed several times to drive, because this machine is win10, thought may be win10 compatibility problem, swap with Win XP virtual machine, but still failed to solve this problem. Until the boss said that it was available on his computer, I brainwave his driver.Jlink dri

Because you've looked through its datasheet and TRM manuals and will not find any relevant introductions.But please don't worry, after reading this post, you will be able to achieve.First, in all the routines of cy7c68013a, the device is enumerated in high-speed mode by default. So what do you do if you want to implement the default enumeration as a full-speed device? Then you need to change the value of the register. How to change, where to change? CY7C68013A's imple

It's not easy for a novice.and learning from the beginning is a very good thing.WatchTo debug arm, JTAG is one of the following arm 's debug interface protocols. When simulation, IAR, KEIL, ads, etc. have a common debugging interface, RDI is one of them, then how do we complete the Rdi-->arm Debug Protocol (JTAG) conversion? There are two ways to do this:1. Write a service program on the computer, parse the RDI command in the IAR,

With the 32-bit ARM7 chip lpc2129 and Keil compilers, the problems encountered in project development are as follows:To define a byte array:BYTE array[10] = {0};Then cast the address array[1] and assign the value:* (UINT16 *) (array[1]) = 0xaabb;Then read the contents of the array, found that the assigned element is array[0] and array[1], read the content is:Array[0] content is 0XBB, array[1] content is 0xaa,array[2]-array[9] are 0.is very puzzled.

SEGGER's jlink sdk is not free of charge. Many problems may occur during API debugging, su

When you look at someone else's project with Keil software, you see that there are. h files and. c files in the project, so it's confusing to gather the data.1, the first is to use Keil software to see the project, so the project saw. h and. c files must be related to the Keil software (compiler).1.1, the work of the compiler process:1.1.1, pretreatment phase.

take a detour. Here is a simple sample program to say how to compile, download, Debug. In the original Windows environment, I was developed with Keil UVision5, but also left some code, so directly took a serial port of the sending program as an example, the code is as follows. /*===================================== Include headers =====================================*/#include " Stm32f10x.h "/*===================================== functions defini

Before doing STM32 development in order to obtain the STM32 chip internal data into a variety of methods. The first is to use the serial port to send data, and later the system updated to WIN10 after the serial drive is incompatible, so found another way to debug. I was developing stm32 in Keil, STM32 program was compiled by Keil compiler and then downloaded to the chip via Jlink. In debug mode, you can vi
