I have two .msi installation packages, A.msi and B.msi. Both can be installed correctly in Windows XP. But in XPE, one can be installed, and the other fails with the error "This installation package c...
[font=宋体][size=3] The stm32f769 development board integrates a WiFi interface, which lays the foundation for the development of IOT applications. With the help of the onboard LCD display and some API ...
I have been working on wind power pendulum for 15 years. When I input y-axis sine wave and x-axis is 0, the output amplitude cannot keep up with the input. I don't know what the problem is. I beg all ...
I would like to ask, how do I send a byte of data to the host in SPI slave mode? It seems from the STM32 manual that MOSI and MISO are sampled on the same clock edge, but there is only one SPI data re...
I am currently working on a laser pre-circuit, a transimpedance amplifier, referring to the specification sheet of opa847, and the chip I use is also opa847. Because the circuit is relatively simple, ...
Traditional broadcasting systems generally need to be operated manually at a fixed time, and can only realize one-way broadcasting with few functions. Traditional bell ringing equipment has a singl...[Details]
