• Touch screen driver for chip ft5336 implemented
• Added new object ICtrl designed for handling input events. It allows also for software gestures recognition and recording
• Added handling of %b specifier in printf (allows for printing numbers in bits format)
• Added program paint - simple program for drawing (it was created just for tests of touch screen)
• Added upng library - library for loading and analyzing PNG files
• Added functions fgetc and fgets to the stdio API
• Added function oC_ColorMap_DrawTriangle for drawing triangles
• Added function oC_ColorMap_DrawRect for drawing rectangles
• Added functions memset_u16, memset_u32 and memset_u64 for faster setting values in the memory
• Added function oC_ColorMap_DrawBackground for quick drawing background color
• New library Widget has been added - allows for drawing widgets for handling human interacts
• Fix bug in scanf with reading numbers that starts with the 0
• Speed up memory allocations by adding free area cache
• Added support of multi layers, that can be easy switched in color maps and screens
• Added program elfread for parsing ELF files
• Added makefiles and possibility to compile a program as an elf - thanks to that it can be dynamically added to the system
• Added "Hard Fault Reason" to the hard fault message and killing the process that caused the hard fault instead of rebooting the system
• Added cbinread program for analyzing CBIN files
• Implementation of auto-filling full matched string in the chell
• Added common script build.cmd to provide the same build command for unix and windows
• Fix problem with %llu in printf
• Added simple program diff for comparing text files
• Added driver spi with lld implemented for STM32F7
• Added program spi for dynamic configuration and test SPI
• Added new driver type STORAGE_DRIVER - the type is for handling storage devices such as SD card, memory flash, etc
