the only programming languages i have ever been half-way competent at are python and pic assembly. nothing inbetween

this thread has got me itching and now I want to learn ARM microcontrollers is this a good idea/what should I buy?

Werthog 95 posted:i'm either gonna get a pic or hook up the bus pirate to this teensy thing and see what's goin on i guess thx for the help when I tried to figure out how usb worked on a low level in order to program a usb device it got way too complicated for me almost immediately. I do not recommend this unless you are a better programmer than me (probable) or you can find someone online who already has 90% of the work done (also probable)

putting "pic microcontrollers" on my resume got me a job interview once. that's pretty much the only salient pro I have.

I was never that good at microcontrollers I just liked them because I thought "wow you can take a circuit that requires hundreds of logic gates and just program a single chip to do it!"

I'm pretty much the opposite now because I don't like high level programming but I want to know how to build things out of transistors

re-teaching myself microcontrollers update: I have received the texas instruments tm4c1294 launchpad and managed to program an led to blink on and off with some example code. very satisfied so far.

this thing's been sitting around forever and I finally tested it. it works fine there should be some use for it

Mido posted:you hook up probes to the inputs imagine you're reading a circuits voltage, and simulatenously you're drawing with a pencil horizontally across a piece of graph paper at a constant speed. now while moving the pencil is moving horizontally at the constant speed, you move it vertically up or down to match how high or low the voltage is you're an oscilloscope!

can someone help me pick out a display to buy to hook up to a microcontroller? previous experience: making a single 7-segment display spell out "yourE gAy" one letter at a time. I'm looking at stuff like this http://www.adafruit.com/products/661 http://www.adafruit.com/products/358 but I dunno what products/stores are good I don't have any specific goal in mind I just wanna buy one and goof around with it

where do you even get probes for something like that? e: have you considered "donating" it for a tax write off? Tin Gang fucked around with this message at 19:53 on Dec 31, 2014 |

thing I heard from an old engineer the other day: you know at a high enough frequency, electricity will destory your nerves before anything else, so you can't even feel it killing you. so what is the first thing you notice when being shocked by a high frequency voltage? the smell of flesh burning, of course!

currently planning to try getting sound output from a microcontroller. I think I'll use an msp430 to read sound data in AU format from an SD card and output everything to an external DAC welp that's the tin gang half-baked electronics project update hope you liked it
