Compiler can save RAM doing this...

[CGEngineering]

Hi,

i wrote a function to pass strings through USARTs (why does mikroC not integrate a function like this?), as it done by many mikroC users:

Code: Select all

void Usart_putstr1(char* sBuffer){
   unsigned char i;

   for (i=0; sBuffer[i]; i++) {
      if (sBuffer[i] == '\n')
         Usart_write1(13);  //return
         else Usart_write1(sBuffer[i]);
   }
}

that i can use like this:

Code: Select all

Usart_putstr1("This is how to save some RAM/n");

But i noted that passing strings like this wastes a lot of RAM. Can mikroC team improve that, in order to load strings between "..." in ROM?

If you define the string as const, no RAM will be used to store the string.

E.g.

Code: Select all

void Usart_putstr1(const char* sBuffer)

Ok... but why do mikroC team do not include in their libraries something like this ?

Should i post in this thread my functions to send strings through Usart 232 and 485 half-duplex (or 232 with RTS)?... maybe they can copy&paste

They have... the const keyword is a part of their C implementation and means in this case that characters are stored in flash. Wasn't that your original question?

Writing a wrapper of this kind is a 30 sec job. And you just have to do it once and keep it in your own private lib, so what's the problem?
