Serial hex monitor for arduino

Serial hex monitor based on 6502 hex monitor (wozmon) with some differences in the syntax. It supports upper/lower case hexadecimal literals and aditional simbols for examine-block and store.

Finding adresses

Interesting addresses to poke can be found inside the compiled elf with the toolchain's readelf.

Example

Lookup the address for static uint16_t interval (0x00800100 here):

$ {toolchain}/avr-readelf {build-path}/serialmon.ino.elf -all | grep interval
    40: 00800100     2 OBJECT  LOCAL  DEFAULT    1 _ZZ4loopE8interval

Ignore the MSD; only 4 LSD matter. Type 100: 50 0 and return on serial monitor

The builtin led will flash faster.
