Disk-Editor (Hard disks, floppy disks, ZIP-disks, USB flash drives, CDs.Memory sections are tagged with data-folds.Available as a portable and installable edition.This includes a responsive interface and progress indicators for lengthy operations. In addition memory-sectionsĭefine a foldable region and inaccessible sections are hidden by default.įurthermore a lot of effort was put into making operations fast and efficient, instead of forcing you to use specialized functions for technical reasons or arbitrarily limiting file sizes. Drives and memory can be edited the same way as a regular file including support for undo. The easy to use interface offers features such as searching and replacing, exporting, checksums/digests, insertion of byte patterns, a file shredder, concatenation or splitting of files, statistics and much more.Įditing works like in a text editor with a focus on a simple and task-oriented operation, as such functions were streamlined to hide differences that are purely technical.įor example, drives and memory are presented similar to a file and are shown as a whole, in contrast to a sector/region-limited view that cuts off data which potentially belongs together. hex file currently on your micro:bit, you can do so using uBitTool.HxD is a carefully designed and fast hex editor which, additionally to raw disk editing and modifying of main memory (RAM), handles files of any size. hex file onto the originating editor, it can recover the source program again. This embedded source code program ensures that when you drag and drop the. This may be compressed, and it is stored inside the flash memory of the micro:bit (but only if space is available in the flash memory). This is a JSON encoded blob with various data about the script, and also the source code program. Hex files generated by the MakeCode Editor have embedded meta-data inside the. When MicroPythons starts to run on the micro:bit, it looks for a signature at this fixed location, and uses that to determine whether to run the script, or drop directly to the REPL prompt. MicroPython builds take a firmware.hex image (the MicroPython pre-compiled image) and appends your script to the end of it, in a fixed 8K region at a known address. See the Micropython Hex file reference for up to date information. See more information on the micro:bit runtime. hex files for both board variants, you will need to use the respective toolchains for the DAL V1 and CODAL V2. If you can only support a V2 board, the standalone error can be combined with a V2 hex to produce a hex that will fail with an error on a V1 board, rather than failing silently. A V1 and V2 hex can be combined to produce a Universal Hex. These examples show the process of creating a Universal Hex. The best case is to provide a Universal Hex that supports all board variants. This example shows the worst, best and acceptable (when support for V1 is impossible) cases for users. We have created a standalone error hex that can be combined with a V2 only hex to produce a Hex that will work on a V2 board, but error if used on a V1. In these cases, to ensure the best user experience when flashing a hex file to any board variant, the file should always include an error message to signify board incompatibility to the user. There may be cases where it is not possible to support both boards, for example an accessory that is designed only to target the V2 board variant. This is very confusing to users and should be avoided. hex is detected on a V2 board it will throw an error, but a V2 only hex will fail silently on a V1. The Universal Hex format has been developed to ensure the best experience for users when moving between board variants. This tool is based on the Universal Hex JavaScript Library. hex file that will support all micro:bit variants. We have created a Universal Hex Creator tool, to easily create a. hex file will be ~1.8Mb as opposed to ~700Kb in size.Ī Universal Hex JavaScript Library has been written to implement the format and associated detailed specification of the Universal Hex format. A Universal Hex is a file that contains the binary data for both micro:bit V1 and micro:bit V2, in a format that DAPLink can process to only write to memory the data relevant to its micro:bit board.Ī Universal Hex hex file will work on a V1 or V2 board.Ī clear indication that you are working with this format is that a compiled. The latest board revision introduces a superset of the Intel-Hex format that enables compatibility across processor variants. hex file usually starts writing data to the same fixed location in memory, so depending on the toolchain, we might expect the first line of the file to start like this:

All lines end with a checksum byte that can be used to verify the integrity of the data.Ī micro:bit.

Intel hex consists of records of data, with the address in memory to store the data at the start.
