Using Darrel Tan’s Programming the ATTiny10 instructions and a SOT-23 breakout board by Raphael, I was able to flash one of these very small MCU chips. Given the small package, these programmable devices can be dropped just about anywhere on a circuit that a transistor would be used.

Unlike Tan, my FTDI breakout cable does not have DTR, so the reset pin on the chip needs to be pulled low manually to put it into programming mode, and the pinout adjusted. Full instructions after the break…

Have you ever wondered how to make sense of hexdumps?

Or been curious to know what exactly does a bxeq lr instruction mean in assembly?

If so, then you should sign up for the introduction to assembly programming and reverse engineering class. You can learn assembly programming and machine architecture using reverse engineering techniques on your own code. In this class we will write code, compile it into an executable and then disassemble it to learn about registers, stacks, branches, function calls and argument passing, structs and other common idioms.

Experience with any programming language is required; the examples in the class with be in C, with dissassembly into ARM assembly. Bring your own laptop with arm-elf-gcc and associated binutils installed to follow along.

Yes there is no laser night tonight. Why? Because its HALLOWEEN!
So please go give children candy instead, and leave some for us adults too. Laser night will return next week at its regular place and time.

We’re all out trick-or-treating tonight, so lasering will have to wait for next week.

Don’t forget that Sunday, 10/23, we have two back-to-back excellent workshops at Resistor: Alexis’s HTML5/CSS3 deep-dive workshop (sold out), followed by pumpkin hacking for Halloween.

The pumpkin party starts at 4pm. Please register (free!) on Eventbrite to RSVP. We’re thinking circuits, laser cutting, and maybe more.

We have a very small number of pumpkins available, along with cutting tools. Please BYOPumpkin. If you’ve got orange or purple LEDs or weirdo electronic components (or UV LEDs?!), bring those. We wouldn’t say no to contributions of snacks or tasty libations, either.
