[p=26, null, left][color=#646464][font=Arial]Android's startup speed has always been criticized. Although the hardware speed of Android devices is getting faster and faster, with the emergence of new ...
Recently, when debugging SPI SPI1 and using DMA1 Channel3 to send data, I found a strange problem. When the highest bit of the last data (byte in my case, because the data size is selected as BYTE) of...
#includeint main() { char *p="abcdef"; //Many books say: p is on the stack, "abcdef" is in the data area p[2]='W'; printf(p); getchar(); return 0; } This program compiles, but what program will fail w...
I am a beginner and want to design an FFT module, which involves pipeline, so I added a clock pin to lpm_mult. However, when I use ModelSim to simulate, the following warning is generated, and the wav...
