I just deduced the schematic diagram of a 5-port Ethernet switch based on the actual device. The main chip is DM9081. It is in PROTEL99SE format. [[i] This post was last edited by Simon on 2009-5-12 1...
Interrupts are a major feature of the MSP430 microprocessor. Effective use of interrupts can simplify programs and improve execution efficiency.
MS430 has many interrupts, and almost every peripheral ...
When debugging the 5509A program, I found that I could not connect to the emulator, but I could do it by changing the board. It took me a while to solve this problem. I recorded the test process and s...
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]

1. Before installation, you should first check whether the inverter is damaged during transportation.
2. When selecting an installa...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
