Data is now discarded in that case; - before, leaving data in the hardware would cause infinite interrupts - one most MCUs since you must read the data in order to clear the - interrupt. - * arch/arm/src/lpc17xx/lpc17_can.c: Added a CAN driver contributed by - Li Zhuoyi (Lzyy). - * include/stddefs.h and sys/types: Added type wchar_t. - * fs/fat/fat_fat32dirent.c: Move all FAT directory operations to this - new file; Implement VFAT long file name support. - * fs/fat/fat_fat32dirent.c: The configuration CONFIG_FAT_LCNAMES has - been around for some time but never tested until now. This setting - will mimic the NT 8.3 file name behavior: File names or extensions - may be all upper or all lower case (but not mixed). If - CONFIG_FAT_LCNAMES is not selected, all filenames are strictly upper - case. - * configs/stm3210e-eval/nsh2: Console is back on UART1; Added - examplex/nx as an NSH "built-in" command as a demonstration. - * fs/fat/fs_fat32dirent.c: Fix an important bug in the directory - allocation (fat_allocatedirentry()). I looks like it could be - initializing the wrong sectors! NOTE: This function was in - fs_fat32utils.c in earlier releases. - * arch/arm/src/stm32_sdio.c: Correct an important DMA-related bug; - SDIO transfer completion events and DMA completion eventes were - not being coordinated correctly. - * configs/stm3210e-eval/nsh2: Enable FAT long file name support - * sched/sem_timedwait.c: Add the standard sem_timedwait() interface. - * graphics/nxfonts/nxfonts_getfont.c, nxfonts_bitmap.c, - Makefile.source, and include/nuttx/nxfonts.h: Support for multiple - fonts included. A new interface, nxf_getfonthandle() takes a font - ID and returns a handle that is now used at all other font interfaces - to specify which of the multiple fonts to use. - * arch/arm/src/lpc17xx/lpc17_syscon.h: Fix typo (reported by Li Zhuoyi). - * configs/stm3210e-eval/nsh2: Extended to support two new commands: - 'msconn' will connect the USB mass storage device; 'msdis' will - disconnect the USB storage device. - * tools/bdf-converter.c. This C file is used to build the bdf-converter - program. The bdf-converter program be used to convert fonts in Bitmap - Distribution Format (BDF) into fonts that can be used in the NX graphics - system. - * include/nuttx/nx: Move all NX header files from include/nuttx to - include/nuttx/nx. - * drivers/usbdev/usbdev_usbstorage.c and arch/arm/src/stm32/stm32_usbdev.c: - Correct a memory leak when the USB mass storage driver is connected and - then disconnected from the target. The write requests were not being - freed. NOTE that the unregister logic in the STM32 needed to call - stm32_reset() in order to return the write requests to the USB mass - storage driver; it is possible that a similar but could exist for other - architectures. - * graphics/nxfonts/nxfonts_*.h: Add serveral more new fonts - * arch/z80/src/ez80/ez80_serial.c: Fix some errors in serial driver - setup for UART1 (submitted by Paul Osmialowski). - * drivers/input/tsc2007.c and include/nuttx/input/*: Add a generic NuttX - touchscreen interface.
