I would like to ask everyone, there is no problem with the circuit I connected, and the reference voltage and other aspects are normal, but there is no data output. It becomes zero as soon as the powe...
My system is pxa270. When the dm9000 function runs here, NdisRawWritePortUchar keeps occupying the bus, the chip select is always pulled down, and the system freezes. I don't know how to set it to rel...
I've been learning about 28335 recently, and I'm thinking about making an experimental hardware platform myself. I'm learning the software. The board at the bottom has flying wires to convert 12v to 5...
