Added upload command for icon: It is now possible to upload a custom icon which is shown during startup and while writing settings (instead of the HW string). The icons are limited to 256 colors and 800x480 pixels. The icon may not be larger than 200kByte because of storage avability. For upload the same CRC functions as for the common firmware updates are in use,

# How to Make an Uploadable Firmware File for the OSTC4 #

Generated BIN files from the SMT32 Workbench need modification in order to be installed via the OSTC Companion onto the OSTC4. 

## Build Command Line Tools ##

These can be found in /ostc4pack (For Windows, CPP sources available)

## Run the Tools Manually ##

1. Copy generated BIN files (From the Release or debug directory) into /ostc4pack. Or: Modify .bat files to point to your Release or debug directory.
2. run step1_create_OSTC_RTE_upload.bat and/or step1_create_OSTC4_firmware_upload_bin.bat (Depending on which part you made changes)
3. run step2_create_OSTC4update_bin.bat to create final OSTC4update_xxxxxx.bin, with xxxxxx being the current date in YYMMDD format. This will add important checksums required for the OSTC4's bootloader to accept the file.
