Logic now assumes a single LUN if the get - Max LUN request fails. - * include/nuttx/arch.h, lib/stdio/lib_libvsprintf.c, lib/stdio/lib_fputs.c: Add - a new configuration option to support extracting strings from FLASH or EEPROM - or other memories where the string data cannot be accessed by simply de-referencing - a string pointer. - * arch/sim/src/up_romgetc.c: Used to test the basic logic to access strings - without directly de-referencing a string pointer. - * arch/avr/src/avr/up_romget.c: Used to access strings that lie in the first - 64Kb of FLASH (But I still haven't figured out how to get strings to reside in - FLASH without using the PROGMEM attribute). - * configs/teensy/src/up_spi.c: Correct reading of SD CD and WP pins (was reading - the wrong register. AVR SPI now appears to be functional. - * arch/avr/src/at90usb/at90usb_usbdev.c: Correct USB initialization. Interrupts - were being enabled BEFORE the interrupt handler was attached. - * configs/sure-pic32mx: Add a configuration for the Sure Electronics, "Advanced USB - Storage Demo Board," Model DB-DP11215 (http://www.sureelectronics.net/goods.php?id=1168). - This board features the MicroChip PIC32MX440F512H MCU. (Untested on initial - check-in). - * configs/stm3210e-eval/nsh2: Add another NSH configuration for the STM32 with - some different properties. - * CONFIG_NSH_CONDEV: Add a configuration option to allow using a different character - device (such a a different UART) for the NSH interface. This allows, for example, - debug output to come from the console device while using another device for NSH. - There are some issues on initial check-in: NuttX doesn't have termios and the - console device has special properties that make using NSH awkward. Examples: - No CR-LF expansion, no character echoing, no command line editting. - * arch/arm/src/stm32/stm32_lowputc.c and stm32_serial.c. Correct seversl bugs - involving serial port configuration. These bugs are only critical if you - are trying to using multiple UARTs on STM32. - * configs/stm3210e-eval/src/up_lcd.c: Add a driver for the STM3210E-EVAL's LCD. - * configs/stm3210e-eval/nx: Add NX configuration for the STM3210E-EVAL. - * configs/nuttx/arch.h (and arch/arm/src/stm32, configs/*/src/up_buttons.c): - Standardize interfaces exported for button support and button interrupts. - * configs/stm3210e-eval/src/up_buttons.c: Add interrupting button support. - Also fixes a few errors in STM3210E-EVAL button decoding. - * configs/stm3210e-eval/buttons: Add a configuration to exercise STM3210E-EVAL - buttons. - * arch/arm/src/stm32/stm32_gpio.c: GPIO interrupt handling for pin - numbers were being aliased: 5-9 together and 10-15 together. Extended - the logic to peform decoding of GPIO interrupts and unique dispatching - for all 16 pins. - * configs/stm3210e-eval/nxtext: Add a configuration for the apps/examples/nxtext - example. This example focuses on placing text on the background while - pop-up windows occur. Text should continue to update normally with or without - the popup windows present. - * arch/arm/src/common/up_checkstack.c: ARM stack overflow checking submitted - by Hal Glenn. - * arch/arm/src/lpc17xx: Changes to compile successfully with no serial console - (also submitted by Hal Glenn). - * graphics/nxfonts/nxfonts_convert.c: Fixed a critical bug that caused - when renderer some fonts with bits-per-pixel > 8 - * graphics/nxbe/nxbe_move.c: Fixed an error in the graphics move logic (This - was a previously untested interface). Basically, there is some confusion - between use of (x,y) as a relative offset or as an absolute position. - * graphics/nxbe/nxbe_close.c: Fixed an important graphics system bug: - When a window is closed, the display was not being updated. The old - window graphic was left on the display for a time. + * Makefile: Added a export target that will bundle up all of the NuttX + libraries, header files, and the startup object into an export-able + tarball. + * arch/arm/src/lpc17xx/lpc17_can.h: Correct some typos in the CAN + register definitions. + * drivers/serial/serialirq.c: Correct an error that can occur if the + serial RX buffer becomes full. 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.
