[SCM] keil_iodemo DL : 0: The project KEIL_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the Keil ARM 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. -The project shows how to use me mory allocation routines (malloc) and char I/O (printf, Scanf) via a serial interface with the Keil ARM t oolchain.
