Browse Source 
Extended python script to support writing .bin files directly. This avoids the additional step of using objcopy.

Updated the 001_PINECIL.bin file to match the PNG.

To flash the logo, use the following steps: To flash the logo, use the following steps:
- `python3 img2ts100.py input.png logo.hex` - `python3 img2ts100.py input.png logo.bin`

This will use the objcopy tool to convert the hex to a binary file, and then use dfu-util to flash it in the right location. The converter will create a binary file if the .bin extension is used. Use dfu-util to flash it in the right location.
If you do not have `riscv-nuclei-elf-objcopy` installed, you can generally use any objcopy tool from any toolchain you do have.
