Hello,
I'm working with the AT91RM9200 - the USART is already configurated and works but I don't know how I could use the printf-function for the usart.
Now I'm sending a character with this function - it works, but it's ver uncomfortable if I want to send one sentence or numbers...
char a[11] = "Hallo Welt"; for(int i=0; i<11; i++) { while( !(COM1->US_CSR & AT91C_US_TXRDY) ) continue; COM1->US_THR = (a[i] & 0xFF); }
Is there a possibility to use the printf-function for the first USART / not the DEBUG-Unit at the AT91?
printf("Hello World\n");
best regards Johannes
right, at the beginning of the retarget.c file there are comments, I don't posted...
But the error message says which things are not correct... I created a complete new protect file and now it is working... I only copy the whole c-code in the new project file..
But it would be very interesting what the error was / or is.
The errors that you show are consistent with you compiling this C file as a CPP file. Notice the reference in the error message to the std namespace.
There is a switch to the compiler to compile .c files as cpp files. Are you using it?
yes that's the reason... I forget to delete cpp from the linker...
