I would like to ask how to write a web server that pops up a username and password box (same as a router) and cannot access the web page if the input is incorrect. Only when the input is correct can t...
I just came into contact with STM32F103. The GPIO example has been running normally, but the USART\printf example cannot run normally. There is no response on the board. Even the characters at the beg...
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
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]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]
1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]
