In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
LAN8720 configuration: IP: 192.168.192.30 Gateway: 192.168.192.1 A high frequency of ARP packets is detected The content of the packet asks for the mac address of 192.168.192.1, and asks the resp...[Details]
1. Introduction to MC68K CPU The MC683xx series of microcontrollers are composed of the famous MOTOROLA 32-bit microprocessors such as MC68K, 68020, 68040, and the compatible 68K, CPU32, CPU3...[Details]
The independent watchdog of STM32 is driven by a dedicated internal 40Khz low-speed clock, that is, it is still effective even if the main clock fails. Here we need to note that the clock of the inde...[Details]
The clock system of STM32 can be directly summarized in a diagram (from the STM32F10X reference manual). The following is an analysis of this diagram 1. STM32 input clock source 1.1 Function of cl...[Details]
Timer Interrupt The timer function of STM32 is very powerful. There are advanced timers such as TIME1 and TIME8, general timers such as TIME2~TIME5, and basic timers such as TIME6 and TIME7. In th...[Details]
It is required to use MCS-51 microcontroller to sort data. 1. Sort the 8 data in ascending order; 2. The data to be sorted is stored in the internal data memory address units 30H-37H, which are 34H, ...[Details]
