[@gloverelaxis]

Thank you so much for your labour Eli! These things are really cool and could be / are incredibly productive for humanity with the right applications. They're 100-1000x cheaper than I assumed a rice-grain-sized computer would cost! I can think of so many ways these things could help people (especially so with tiny rechargeable batteries and solar cells). It's miraculous to me that you can fit a timing oscillator in such a small thing, let alone a CPU, RAM, and ADC! This alone has inspired me to learn far more about low-level / low-resources programming. The price and size is a huge, huge deal.

[@CollinEddy]

This has to be the best AVR introduction I've ever come across, much less specifically for the ATTiny10!

[@BrainSlugs83]

Ben, you rock so much. Showing the actual dates sheets and raw code from start to finish; building your own ICSP board, there's really something for everyone here. This is how I got my start with AVR chips back before arduino; and there is huge nostalgia factor here for me. One thing to keep in mind (may not be relevant to this chip), but in general when working with raw MCUs is a good idea to include a decoupling capacitor (pretty much any value ceramic cap) between VCC and GND because toggling the IO lines can cause a drop on VCC causing the MCU to misbehave (on some lines of MCUs, like the PIC16 it can cause them to just reboot mid program!) anyway, great fucking content, I love that you showed the whole development process. -- And hey, you should take a look at the V-USB library for the ATTiny / ATMega (you can create a bit bang HID device without even needing a crystal oscilator, just a few zeners! Though you'll need a bit more ram than 32 bytes!) -- Happy Holidays Ben, you fucking rock! Keep up the good work!

I'm glad i leaned programming microcontrollers like that in university and get why it can be important but man am I glad an arduino is all I need for most projects. So i don't have to spend so much time in the datasheet ;D great video, well explained ;)

[@ray-charc3131]

What the importance of it is it's tiny and does the right amount of works or functions as well as is cheaper than an normal arduino chip.

[@MakenModify]

@@ray-charc3131 sure I also allways have some attinys laying around for when i need a small form factor. But i referred more to the IDE than the boards itself. Sometimes it's important to have every bit of control over the chip but sometimes it is just more convenient to not have to deal with the registers.

[@NolePTR]

Never used an Arduino myself. It's just ridiculously overpriced for what it is, and massive and slow. If I need to actually do some more intensive calculations, I use an ESP8266. I use ATTINY85s for most my stuff with the TinyISP programmer. Will probably get an ATMEL ICE or similar for debugging, and stuff.

[@MakenModify]

I feel I'm attending a high level course on ATTiny programming, mixed up with a little bit of electronics and logics.

[@argcargv]

Shouldn't there be a current limiting resistor between the optocoupler and the pnp transistor? When saturated the pnp base will be about 11.3 v which will be across the optocoupler transistor. Seems a bit extreme.

[@BenHeckHacks]

I drew the schematic after I built it. Yes there was a 1K between them. Good catch!

[@electronash]

@@BenHeckHacks Well worth adding a few decoupling caps to the adapter board, as I had many issues years ago when programming PIC and AVR chips without any caps. Unless you already put the caps on the underside of the board, of course. ;)

[@jamesrbrindle]

This is where i am still a newbie in electronics design - knowing when current limiting resistors are needed with this scenario

[@argcargv]

@@jamesrbrindle Any diode junction, once conducting, will see an exponential increase in current with an associated further increase in the voltage applied. To prevent runaway current a limiting resistor is usually applied. In this case the base-emitter junction is also a forward biased diode and like a LED or other diode can potentially draw an arbitrarily large current if some mechanism isn't provided to stop it. So mostly knowing where to put a limiting resistor is a case of identifying the diode junctions that have a low resistance current path between the power rails. To quickly see this takes experience, but understanding how to determine if they are needed is basically as I described.

[@WoodmanFFM]

Just wanted to write this, but then I thought that someone MUST have caught this by now and found your comment after scrolling down for quite a bit... ;-) Alternatively, one could also use a P-Channel FET, with the added bonus of preventing the voltage drop across the PNP. Not that it would be strictly necessary, but 12V is 12V... :-D

This is how the Ben heck show should have been. This is incredibly informative on so many levels. I especially enjoyed the programmer build right at the start. Unfortunately the audio still has some issues.

[@Xilefian]

For function args most compilers for most architectures are likely to pass them by register, rather than store in memory, so the concern should be matching the register size, rather than keeping memory usage light. This architecture has 8 bit general purpose registers, so uint8_t would likely be most ideal anyway.

[@BenHeckHacks]

That makes sense, considering RAM access has a 2 cycle penalty. Not shown in video but doing the same toggle test in assembly yields an identical speed.

[@Xilefian]

@@BenHeckHacks this is a very nice video, by the way - you've managed to describe incredibly low level C programming in quite the understandable manner. Reminds me very much of Gameboy Advance programming in C.

[@etopowertwon]

@@BenHeckHacks Even more, if you enable optimisation, pins function gets inlined into the main AND it's optimised down to the single instruction: cbi for clearing bit, sbi for setting bit Here's the assembly listing: godbolt.org/z/8c1pY5 And if you mark the function as static, compiler will know that there are no other object files that will ever call it and remove completely godbolt.org/z/Du-HFP

[@Adolf1Extra]

I'm curious why you would be doing this in C at all and not C++ where you can leverage constexpr and templates for compile time computations so as many things can go on the flash as possible. Also yes, compilers are way smarter than you, just make sure your data is word size and it will fo magic to your code. I recommend watching cppcon presentations on the topic and toying around with godbolt just so you can witness how truly powerful C and C++ compilers are.

I haven't dug through the datasheet for the optoisolator, so I might be going off half cocked; but, 100 ohms seems a little small on the current limiting resistor for the internal LED. Outside of that, excellent video. Reminds me of the pain of learning to program PIC chips when I was first getting started. This type of material should be a prerequisite for new developers, especially those that think Java can do anything. ;). Doing useful, timing sensitive work with 32 bytes of RAM and a tiny amount of flash is the best way for beginners to appreciate limited resources and gain a true perspective on what's really going on behind the scenes of "luxury" programming languages.

[@AlexHuebi]

At the Programming Part: in school, we used to use Atmel Studio as our main IDE, but when compared to Visual Studio with the Visual Micro extension, then the VMicro is much more convinient and forgiving when using a CH340 instead of the CP2102. And you have the features like autocomplete or one-click to compile and program. (and no need to press the reset switch while programming the atmega2560)

You can use the transistor side of the the optocoupler as a PNP transistor, provided it is rated to work with 12 volts, which a great many are. There is no need for the additional PNP transistor.

jajajaja, definitivamente el mejor y mas gracioso vídeo sobre programación de micro controladores que he visto , felicitaciones .

Wanted to see the uC. Learned a lot about Eagle, and some electronics tricks! Good content. Enjoyed :D

I was once scared of SMD soldering too. Yep, turned out to be quite easy with patience, even for the really small chips! Certainly not gonna be going smaller than 0603 for resistors/caps... that's still a bit fiddly for my big shaky hands!

[@LanceThumping]

@25:00, couldn't you write the function so that the compiler would basically completely optimize it away? As long as your pins are known at compile time then the entire function can be optimized to the same point as the previous method.

I was about 3min in and thought “wait a second... I know that voice!” Glad to see you have your own channel!

[@riquardi]

where else is he active or known? Im curious!

[@jeroenenmoniquetaverne9284]

On Q1 I am missing a base resistor. And why not use the optocoupler to directly switch the 12 volts rail without having Q1? Also why does the LED in the optocoupler need a pullup? When RST is floating, the LED won't light up anyway.

A good tip that mounting to breadboard before soldering. I'm going to solder next module like a pro.

i've missed this man so much

[@Sharklops]

This was freaking amazing. Please more of this kind of stuff!

[@Nichetronix]

What's the point of the optocoupler? The grounds are common anyways, so no real isolation. Seems you only need the PNP transistor to switch the 12V.

[@Stabby666]

Steve Bragg it’s because the PNP must be pulled to 12v on its base so it doesn’t conduct - the optocoupler keeps the 12v separate to the 5v logic used to control the reset pin state.

[@gblargg]

I'm wondering why the opto couldn't have directly switched the 12V. I doubt the AVR draws much current on the reset line.

You Sir are one of the YT GOATs. Thank you!

15:22 Did you solder that blindfold?

[@DavidLindes]

30:52 - ok, I'm curious: did you pick up "that's a bit how-ya-doin'" from Dave at EEVBlog, or elsewhere? Because that's where I'm used to hearing it. :)
