The A/D module is connected to the MCU, which is connected to D12 externally, and then connected to arm9 through the USB port. The arm uses the wince5.0 OS. The MCU reads the A/D data in a timed manne...
[font=微软雅黑][size=4]I was on vacation yesterday, but I was shocked by a wave of messages from netizens in the afternoon. They all asked me if I knew that PCB manufacturer Jiali Chuang and Jiepei were i...
The hardware wiring of tlv5620 is as shown in the figure. The reference voltage (2,3,4,5) and VDD are connected to the 3.3V terminal of dsp, and (6,7) are connected to the SPISIMO port and SPICLK port...
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
Designing for automotive LCD displays larger than 5" can be complex. The display source driver requires a supply rail called analog voltage device drain (AVDD) in the 10V to 15V range and two supply ...[Details]
In order to strengthen the management of new energy vehicle charging facilities in our city, prevent and reduce accidents, protect the lives and property of the people, and improve the public safet...[Details]
The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]
Recently, the US embargo on ZTE has attracted much attention. Let's take a look at the relevant content with the automotive electronics editor. On April 16, local time, the U.S. Department of Co...[Details]
Friends who work in the photovoltaic industry, do you still remember the hard work on June 30 last year? How many people worked late into the night for months in a row just to connect to the grid a...[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]
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]
This is a "cooperation" that is related to the future development of China's semiconductor industry. Let's follow the embedded editor to learn more about the relevant content.
Last week, a...[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]
Assume that the crystal frequency of the microcontroller is 6MHz. It is required to use timer 1 in mode 0 to generate a continuous square wave pulse with a period of 500us, and output it from P1.0. T...[Details]
