writing my own print function

[hithesh123]

RFDATA_BUF[102]; Is there enough ram available?

Try const unsigned char for all your messages and use const unsigned char * as argument for your function. RFDATA_BUF[] has consumed 102 bytes of RAM. Remove your function and Compile and see how much RAM and ROM is left free.

If I use const char, then how would I call the printf_uart function.

for example, unsigned const char *strln1="error1";

How would I call the function - printf_uart(strln1); ?

void printf_uart(const unsigned char *str);

...

const unsigned char *msg1 = "error1";
const unsigned char *msg2 = "error2";

...

void printf_uart(const unsigned char *str){



}

...

printf_uart(&msg1);
