The 'GPIO' project is a simple program for the STM32F103RBT6 
using Keil 'MCBSTM32' Evaluation Board and demonstrating 
the use of the GPIO ports.

Example functionality:                                                   
 - Clock Settings:
   - XTAL    =            8.00 MHz
   - SYSCLK  =           72.00 MHz
   - HCLK    = SYSCLK  = 72.00 MHz
   - PCLK1   = HCLK/2  = 36.00 MHz
   - PCLK2   = HCLK    = 72.00 MHz
   - ADCLK   = PCLK2/6 = 12.00 MHz
   - SYSTICK = HCLK/8  =  9.00 MHz

 - Pressing buttons S2, S3 move the lit LED.
   press S2 to move the lit LED to the right
   press S3 to move the lit LED to the left
 
The Gpio program is available in different targets:
  Simulator:   - configured for software Simulator
  MCBSTM32:    - runs from Internal Flash located on chip
                 (used for production or target debugging)
