A Windows desktop tool for making sense of compiled 8051 firmware. Open an Intel HEX file and it reconstructs the assembly listing, resolves jump and call targets, and shows how the code is laid out in memory, so firmware you have only as a HEX dump becomes something you can actually read.
Built for the Intel 8051 family and its derivatives, and free to use.
