C8051F350 printf in Debug mode

Sam L

Hi there,

I am new to the embedded systems and trying to learn. I have a C8051F350-DK that I wrote a
program to measure the voltage through one of the analog inputs ( I am using Keil uvision 4).
I added a printf to see the result, so I won't use the WATCH window. I downloaded the code then
debug it (through the DEBUG mode, not the Simulation mode) and it didn't work. Can anyone give
an advice if I am missing something in my settings ?? here is some of my settings :

Project > Option for target > Device > C8051F350 Use extended linker ( LX51)

Project > Option for target > Debug > Use "on the right side" \Silicon Labs C8051Fxxx Driver

Project > Option for target > Utilities > Use \Silicon Labs C8051Fxxx Driver " didn't use *.ini "

Steps: Translate -> Build Target -> Download code to flash memory -> Debug -> Run
---------------------------------------------------------------------------------------------
Thanks in advance

    I am using the same Example from SiLabs (F35x_UART_STDIO.c) which is basically demonstrates how to configure the C8051F350 to use routines in STDIO.h to write to and read from the UART interface. The program reads a character, outputs that character to the screen, and then outputs the ASCII hex value of that character.
    I made sure that J3 is connected (P0.4 pin to the TX signal, and P0.5 to the RX signal. Then change couple setup which are:

    Project/Option for target/Debug======>Silicon Labs C8051Fxxx Driver
    Project/Option for target/Utilities==>Silicon Labs C8051Fxxx Driver

    I set my HyperTerminal to 9600 baudrate, then I tried to download and Its saying the the port is in use. So I forget about the hyperterminal hoping to see result just from "printf" or "putchar" on the UART 1. So I download the code on the chip and debug it, but it didn't show me anything on the serial window. Did I miss any of the settings that I have to include?

    Thanks,
