Hi all,
I have a small starter problem with my LPC2138
I'm using Flash Magic to make the hex file and program it to the arm controller.
I managed to make a serial connection with the terminal on Flash magic, so I can send characters to it.
What I want to do is to print a sentence to the terminal.
this is how I print a character:
void outchar0(char k) { unsigned long a; //local variable U0THR=k; //ascii code to buffer transmitter while((a=U0LSR&0x41)!=0) { } }
But wouldn't you find it interesting that the loop inside a function outchar0() worries about Receiver Data Ready (0x01) or Transmitter Empty (0x40)?
I'd hazard a guess that it was an attempt to get the the thing to respond to a character received by the UART, but yes, it seems quite wrong. I hadn't appreciated that the OP was quite as close to the beginning of the learning curve as now seems apparent.
