NXP targets: Improved baudrate calculation function
 2013-12-02 01:47:45 -08:00
bcostm 3bcf77e4f7 NUCLEO_F103RB: minor changes 2013-12-02 09:22:28 +01:00
Sissors 9f89a4d218 Added (deep)sleep to KL25Z 
Sleep is wait mode

Deepsleep is very low power stop mode

During the interrupt that removes it from deepsleep it will run at low
speed until the PLL is automatically re-enabled after the interrupt.

Michael Moon a249e39826 Improved baudrate calculation function. 
Uses 100% integer math, delivers more accurate results with fewer iterations in less time.

Since it seems most of the NXP chips use identical math, I have also altered the other targets in this commit.

If there are non-NXP chips which use a similar serial block, consider porting to those as well

hototogi 03b79b5920 support GCC_ARM for LPC4330_M4 
- Linker script is based on LPC1768
     number of NVIC is 16 (CORE) + 53 (M4 in LPC43xx) = 69,
    therefor, reserve at the top of RAM0 (address:0x10000000)
    to relocate NVIC vector table
 - startup file is based on startup_ARMCM4.S in CMSIS V3.20
     change NVIC name for cortex-M4 of LPC43xx
 - add GCC_ARM for LPC4330_M4 in python scripts
 - add some descriptions for GCC_ARM

Adam Green 10126e0b2f Increase available RAM for RTX on LPC11U24 
The INITIAL_SP value used by RTX was originally at the 4k limit instead
of at the 8k limit.  The HEAP_START macro was defined to __HeapLimit
but the heap really starts at __end__.  __HeapLimit is just used for
some link time sanity checks to verify that the heap and stack can
grow a bit without colliding.
