For example, #include xxxxx .... void F1(uchar a,b,c,d) { if(a==NULL) //Can it be written like this? .......... } main() { F1(,,3,4); //Or F1(NULL,NULL,3,4) Similar to the writing method in C++..... }...
When I first learned about PSRAM, I had a very naive idea.
Can PSRAM be expanded to XDATA - there are still some memories from the 51 era left at that time.
Later I found that I couldn't find it on Ba...
