The EN1 pin of my LTC3555 behaves in the opposite way to the manual. The manual says it is high level active, but mine is low level active. I have cut off EN1 and tried it with flying wires, but it is...
I have been paying attention to donations from all walks of life. Companies like NetEase usually donate, and I have a good impression of companies that donate. I would like to ask if there are any emb...
When using the database programming that comes with WINCE, when using the CeCreateDatabaseEx function, how are the two parameters of this function defined? I wrote it like this CEDBASEINFO ceDbInfo; c...
If we only consider the limitation of FPGA device performance on operating frequency (assuming that layout and routing delay are optimized to the maximum), then which parameter should be used to deter...
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]
