In the figure below, why does this negative voltage output circuit not work?
Vin=24V, the design requires output -12V,the problem now is that after power on, it can output -12V occasionally, but somet
I am going to participate in the Altera Asia Innovation Contest soon. Can you recommend a topic for me? It's about SOPC FPGA. The board is Alterra DE1/2. I'm begging for help! Thanks, everyone. This i
Some concepts of logic level To understand the content of logic level, we must first know the meaning of the following concepts: 1: Input high level (Vih): The minimum input high level allowed when th
Using SPI synchronous communication,It is found that after initing SPI, when no data is sent, UTXBUF is 0x00 and TXTEPT is 0 (which means there is data in the shift register and UTXBUF);I know this ma
