I am new to VXWORKS and I am not sure if the network card driver is not loaded? Ping also fails. I use ifShow to display: lo (unit number 0): Flags: (0x8069) UP LOOPBACK MULTICAST ARP RUNNING Type: SO...
I used a class CxImage in VC, and there was no problem with compilation and linking (the call of *.lib was also normal). However, when I ported the program to WinCE, I always got the following error m...
Recently, I am working on a project where the sensor interface is a 5V UART TTL level interface, but the microcontroller is an NXP LPC824 3.3V UART interface. I know that it can be implemented with a ...
1 Basic Principles Photoelectric direction finding refers to the use of photoelectric systems to determine the direction of a target. This is an important component of optical radar and optical guidan...
Reset is very important for FPGA design . Some very strange problems that cannot be found are likely caused by reset. I was troubled for several days because I did not understand the reset situation w...
XFree86's Makefile is different from the usual ones, and it's hard to figure out. I searched on Google, and all I found was this article "Cross-compilation scenario analysis (arm-linux) (VI) -- Compil...

In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[Details]
1. Function prototype In the function library officially provided by STM32, you can find functions like HAL_Delay(). This function uses a timer to achieve a more accurate time delay and provides it...[Details]
After searching a lot of information, I finally understood the time base timer. I did not use any library functions but operated the registers directly. The following introduces the systick in STM32...[Details]
1. Usage scenarios In the first case, when using a common STM32 delay function, similar to HAL_Delay(time), since this function uses a loop to judge and delay, when executing this function, the ent...[Details]
The trade war between China and the United States has become the focus. The United States has begun to play the ban card against Chinese technology companies. The ZTE incident shows that if the ban...[Details]
