Uart I/O and Memory Allocation Example for GNU
The project GNU_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the GNU toolchain.
The I/O functions are adapted for the Analog Devices ADuC7000 series using the SERIAL.C module.
The example also shows the efficiency of the Keil CA ARM Compiler run-time library which is tuned for single chip systems.
This program prints the C8051F124 die temperature out the hardware Uart at 115200bps. This example uses the internal 24.5MHz oscillator multiplied by 2 using the on-chip PLL (SYSCLK = 49MHz).
