The microcontroller I use is TMP19A61, written in C. During simulation debugging, I found that the serial port's send register buf could not be written, while other registers could be set normally. Th...
As the title says, when I use the malloc function, I find that the return value is empty. After compiling, RW is only 4k, so there should be no overflow. I checked the map and found that the heap is 0...
The low noise block (LNB) is a key functional block in the receiver chain of a satellite communication system. The LNB basically consists of a low noise amplifier (LNA) chain and a downconverter. Alth...
