|
||
|
|
device. Mountpoint traversal logic.
|
||
|
|
* Drivers: Added support for the TI PGA112-7 amplifier/multiplexor.
|
||
|
|
* LPC43xx: Added clock ramp-up logic to run at 204 MHz
|
||
|
|
* LPC43xx Drivers: SPIFI block driver, RS-485 support, Minimal termios
|
||
|
|
support. Framework for USB0 device controller driver.
|
||
|
|
* LPC17xx Drivers: Minimal termios support
|
||

Add support for STM32 F107 "Connectivity Line" (contributed by Max
|
||
|
|
Holtzberg).
|
||
|
|
Clock restart logic needed for recovery from low power modes.
|
||
|
|
* STM32 Drivers: RTC alarm support. Usable for wakeup from sleep mode,
|
||
|
|
Minimal serial termios support. USB OTG FS host driver (alpha).
|
||
|
|
* STM32 Boards: Add power management hooks for the STM32F4Discovery,
|
||
|
|
Add support for the Olimex STM32-P107 (contributed by Max Holtzberg).
|
||
|
|
* PIC32: Add support for the Pinguino MIPS toolchain.
|
||
|
|
* PIC32 Drivers: GPIO driver now supports F1 analog regiaters (ANSEL).
|
||
|
|
* PIC32 Boards: Add support for the PGA117 on the Mirtoo module.
|
||
|
|
* Calypso: Add support for the SSD1783 LCD on the Compal E99.
|
||
|
|
* Library: cfsetispeed(), cfsetospeed(), tcflush(), memchr(), and
|
||
|
|
memccpy().
|
||
|
|
* Applications: Port of freemodbus-v1.5.0. Add support for testing
|
||
|
|
devices with multiple ADC, PWM, and QE devices.
|
||
|
|
NSH: NSH 'mount' command (with no arguments) will now show mounted
|
||
|
|
volumes. Add new NSH 'df' command. Extended 'help' support. NSH

||
|
|
by Mike Smith).
|
||
|
|
* Build System: mkconfig will not define CONFIG_DRAM_END. A lot of
|
||
|
|
progress has been made on the automated NuttX configuration logic
|
||
|
|
(Thanks go to Richard Cochran).
|
||
|
|
* Documentation: Document ways to customize the behavior of NSH.
|

serial driver will now return with EINTR if a serial wait is
|
||
|
|
interrupted by a signal.
|
||
|
|
* FAT: Fix statfs() file name length.
|
||
|
|
* LPC43xx: Clock configuration.
|
||
|
|
* STM32: Pinmap fixes, SPI driver re-initialization

||
|
|
* STM32 Boards: Correct and lower SDIO frequency for F2 and f4 boards.
|
||
|
|
* AVR: C++ build issues.
|
||
|
|
* PM: Fix a place where interrupts were not be re-enabled.
|
||

|
||
|
|
issues with presenting floating point numbers. NULL definition
|
||
|
|
for C++
|
