Here at PerlMonks you got the sections "Tutorials" and "Categorized Questions and Answers", in addition to the various questions being asked around everyday, there is a wealth of knowledge to be picked of course, the thing is if you really want an approach to learn one thing at a time and learn it well,in a systematic progressive way that is well designed you probably need books coupled with the interactivity experienced here at PM because majority of online tutorials for Perl they only serve to introduce you to the language and they are rather confusing, check the Book Reviews and Perl Reference Materials: Books section for relative info about books and for the modules check the Module Reviews section which perhaps can enable you to set priorities straight with regard to which modules are best for you to pick and use for a certain task at hand.

    [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....
