Projects / vPICdisasm


vPICdisasm is a Microchip PIC firmware disassembler that supports the Baseline, Mid-Range, and Mid-Range Enhanced 8-bit PIC cores. This single-pass disassembler can read Intel HEX8 and Motorola S-Record formatted binary files containing valid PIC program binaries. vPICdisasm is capable of a variety of formatting options, including representing data constants in different bases, and can output directly assemble-able code.

    Release Notes: A critical bug was fixed regarding S-Record reading, which was ignoring valid data records. Output file support was added by way of the -o/--out-file option. Standard input support was added with the "-" file argument, meaning that the disassembler now supports piped input. Intel HEX8 / Motorola S-Record auto-detection was improved by using the first character rather than the file extension. Support for printing of original opcode data alongside disassembly was added.

        Release Notes: A critical bug in program file reading was fixed to support odd byte lengths for Intel Hex and Motorola S-Record records. False invalid record errors caused by newlines in the program file were fixed. Another minor bug was fixed, leading to cleaner compilation.
