   Hello, it seems there is indeed bug in python3 version. Usually you have to provide output bin filename as last parameter, after filename of input hex file. Without output filename my script tries to write binary data to stdout and that provoked error.

   As workaround try to run command with output filename argument:

   python3 hex2bin Blinky.hex Blinky.bin

   According to http://stackoverflow.com/a/908440 IntelHex on Python3 should use sys.stdout.buffer.write to write binary data to stdout.
