Tonight I randomly integrated the official SD card code into fatfs and made a simple video player. It seems to be quite effective. The SPI polling method does not use DMA, and the frame rate can reach...
As shown in the picture, there is a component and a development board. I don't know what it is. I have seen it before. The component is very light. "QINLON" is printed on the back, which is probably t...
Fiber to the home (FTTH) has been a dream and technical direction that people have been pursuing for 20 years. Almost no one denies that FTTH will be the best way to access broadband in the future. Co...
Have you ever worked on PKE or studied cryptography? I want to ask, which encryption method can best resist plaintext attacks ? I want to make a small thing that needs a security verification. It need...
I'm going to post a thread to discuss things related to system performance. I hope everyone can share their thoughts. In the vxworks system, how can we test the system performance to show that this sy...
Use F021.h API to operate fbank. The chip is TMS570LS3137. Bank1 and bank7 can read and write, but bank0 Fapi_setActiveFlashBank(Fapi_FlashBank0); this code will get stuck. Does anyone know? :)...
