In recent years, TP-LINK broadband routers can be seen everywhere. I took a look at one used by a friend's company and found that it also uses an ARM9 CPU. So I would like to ask all my friends, does ...
TI stipulates that a macro can have a maximum of 128 parameters.
I wrote a macro with six parameters. When using the macro, the parameters are relatively long. It would be better if they were written ...
