Next, I'm not sure

my $excel = Spreadsheet::XLSX -> new ('test.xlsx');

is correct.

It's not a common way of laying out code, but adding arbitrary whitespace between tokens in Perl is rarely disallowed. Whitespace is only really needed between tokens if they'd look like another token if the whitespace was missing.

For example, given:

use 5.010; my @foo = split /\|/, q {foo|bar|bar}; foreach my $x (@foo) { say $x; }

... there are only actually two pieces of required whitespace: between "use" and "5.010", and between "foreach" and "my". The code runs perfectly well if you strip out the rest of the whitespace:

use 5.010;my@foo=split/\|/,q{foo|bar|bar};foreach my$x(@foo){say$x}

... though most people would consider the former to be more readable.

    [stevieb]: nice! I just finished a GPS "take me home" device last week, and did a bunch of software updates to it yesterday. I also created a pseudo chip with an Arduino to simulate an IC, where it responds to register read/writes over the I2C bus...
    [stevieb]: ...from an I2C master. It's ugly and there are many changes I'm going to make, but I had not done anything like it before. It's designed for my RPi:: automated test platform; a system that does CI on *all* my RPi modules.
    [shmem]: pseudo chip?
    [stevieb]: well, what happens is the Arduino 'listens' for requests r/w, and does the appropriate thing when it's interrupted based on the 'register' address sent in. It's ugly as it was my first attempt, but I've got great new ideas I'm just sitting.
    [stevieb]: ...down to implement now. Here's the sketch as it currently sits
    [shmem]: well I use I2C and SPI and stuff, but creating a pseudo chip looks to me like lot of indirection and memory clutter... not?
    [choroba]: Are you going to use the device soon? Related to your comment about "not having much time to do a lot of coding"...
    [stevieb]: sure, but I'm just learning ;) I consider it practice to get a good understanding of what goes on *after* an I2C/SPI request is made
    [shmem]: ah ok. Gonna read that. but now....
