Description:1, in the actual project, many times, we need to the sensor or ADC values in the form of waveform display. The usual solution is to use the serial port host computer, USB interface host computer or MDK logic Analyzer function, using these three methods are more cumbersome. This issue for you to explain the J-scope waveform software is simple and easy to use. 2. J-scope waveform display software mainly has RTT and HSS two ways of working. T
I have been using MDK to view and compile the RTT source code. In the past few days, I am bored to remember that RTT officially provided the scons tool to compile RTT. So I would like to try this method and take this note for reference by beginners.

Many people in the Forum said that RTT
, like PHP inserted, and then you can print directly. Just recently learning Nodejs, it can operate files, for us jser like artifact! So I just wanted to emulate PHP insert tags to implement a simple template replacement tool RTT----Replace templete tools, manipulate HTML files through Nodejs, and then replace the output to the target fileIn HTML insert After the substitution, the resulting content is as follows: Implementing the template Replacement
Due to business growth, we need to choose an IDC room managed access. Network quality requirements are relatively high. When IDC gives the test machine, it uses smokping to test, which is the package to be measured. Since we have access machines in all regions. Then from these access machines to test the IDC network quality, compared to the indicator: lost packets and RTT return time delay. And then use Excel, generate a graph, do not know whether the

RTT is a basic technology used in many special effects. It is very simple and important to implement it. However, It is puzzling that only a few articles have been found on the internet for a long time. I don't know if it is too simple or because the technology has been around for a long time. In short, I had a lot
Sometimes use the serial port as the debug output, but sometimes the serial port of the hardware is not so much, inadvertently found can use J-link RTT function, with it no longer need to worry about the lack of debugging window. Specifically how to make reference to a Netizen's post: http://www.amobbs.com/thread-5595476-1-1.html. According to this post, I have a demo routine based on Stm32f103ze, which uses mdk4.7a,j-link4.98b, and the routines see H
RTT learning is concentrated at the application layer, and the underlying code will be involved when necessary.
Startup is the startup code of RTT, similar to UCOS.
void rtthread_startup(void){ /* init board */ rt_hw_board_init(); /* show version */ rt_show_version(); /* init tick */ rt_system_tick_init(); /* init kernel object */ rt_system_object_init(); /* init timer system */

. For embedded systems with larger memory, Rt-thread provides a very efficient slab memory management system.
DiagnosisThe system-provided FINSH shell system enables you to view threads, semaphores, mutexes, events, mailboxes, Message Queuing operations, and stack usage for each thread.

RTT is a preemptible RTOS, and high-priority threads will execute it first.
This routine shows how to seize.
I am too lazy to write this explanation. The following section is from the official website forum:
Because of the higher priority, thread1 takes the lead to get the execution, and then it calls the delay. The time is three system tick, so thread2 gets the execution. You can find a rule in the printed results. After thread2 is printed twice and
Timers are divided into software timers and hardware timers.
A hardware timer is a type of peripherals provided by the microcontroller. It can generate scheduled events without occupying CPU time. The advantage is that the timing precision is high, independent from the CPU, and many other functions such as PWM can be flexibly configured.
The software timer is a scheduled interface provided by the operating system. Its accuracy depends on the tick time of the operating system. The Tick of RTOS is
RTT supports the same priority, but ucoⅱ does not.
If a thread does not call the rt-thread_delay () to let out the scheduler, it will always run, and other threads will always be in the ready state.
A thread with the same priority defines the longest time slice for a single run during initialization or creation, and forces the thread to exit the scheduler.
Here, usert_thread_yield();You can also give way to the dispatcher.

Shader hasn't been written for a long time. Last time I used CG to write several shader FOR THE Paster rendering. Stroke and cartoon coloring. If you draw a stroke, first draw a solid background, remove the front, only look inside, and then draw the stroke object, depth detection is less than or equal to pass. In addition, for cartoon coloring, the color is mainly obtained from a 1D Texture Based on the energy of light absorption on the object surface. These items are available in rendermonkey,
