Hi All
I write a function like this
test.c void a(U8 val) { U8 ch=0;
dev[ch].fun1(val); <--this is a function pointer , it will call the b function
dev[ch].fun2(val); <--Fail here }
void b( U8 val) { U8 dummy = val *5;
writeReg[0x55AA]= dummy; }
after run the " dev[ch].fun1(val)"
The ch varible will be change , so it will fail when run " dev[ch].fun2(val)"
I found the varible is in the same memory address, How can I avoid it??
and how can I know the memory map of all local varible ??
I found the m51 file , the data is map to 18h to 28h
DATA 0018H 0028H UNIT ?DT?TEST
why ch varible is map to 0x40 and same as dummy varible??
Thanks for you kindly help and sorry for my poor english
