+File : SEGGER_RTT.c
+Purpose : Implementation of SEGGER real-time transfer (RTT) which
+ allows real-time communication on targets which support
+ debugger memory accesses while the CPU is running.
+Revision: $Rev: 4351 $
+
+Additional information:
+ Type "int" is assumed to be 32-bits in size
+ H->T Host to target communication
+ T->H Target to host communication
+
+ RTT channel 0 is always present and reserved for Terminal usage.
+ Name is fixed to "Terminal"
+
+ Effective buffer size: SizeOfBuffer - 1
+
+ WrOff == RdOff: Buffer is empty
+ WrOff == (RdOff - 1): Buffer is full
+ WrOff > RdOff: Free space includes wrap-around
+ WrOff < RdOff: Used space includes wrap-around
+ (WrOff == (SizeOfBuffer - 1)) && (RdOff == 0):
+ Buffer full and wrap-around after next byte
+

+ * - Configure the clock system and the external SRAM mounted on

+ * @brief CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
+ * This file contains the system clock configuration for STM32F4xx devices.
+ *
+ * 1. This file provides two functions and one global variable to be called from
+ * user application:
+ * - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+ * and Divider factors, AHB/APBx prescalers and Flash settings),
+ * depending on the configuration made in the clock xls tool.
+ * This function is called at startup just after reset and
+ * before branch to main program. This call is made inside
+ * the "startup_stm32f4xx.s" file.
+ *
+ * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+ * by the user application to setup the SysTick
+ * timer or configure other parameters.
+ *
+ * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ * be called whenever the core clock is changed
+ * during program execution.
+ *
+ * 2. After each device reset the HSI (16 MHz) is used as system clock source.
+ * Then SystemInit() function is called, in "startup_stm32f4xx.s" file, to
+ * configure the system clock before to branch to main program.
+ *
+ * 3. If the system clock source selected by user fails to startup, the SystemInit()
+ * function will do nothing and HSI still used as system clock source. User can
+ * add some code to deal with this issue inside the SetSysClock() function.
+ *
+ * 4. The default value of HSE crystal is set to 25MHz, refer to "HSE_VALUE" define
+ * in "stm32f4xx.h" file. When HSE is used as system clock source, directly or
+ * through PLL, and you are using different crystal you have to adapt the HSE
+ * value to your own configuration.
+ *
+ * 5. This file configures the system clock as follows:
