Getting Started with the tinyAVR 1-series Microcontroller 

I like your references to Steve1989. I watch his videos from time to time just to hear him say "Let's get this out on a tray...NICE!"

Getting pretty good at the Dave Jones impersonation 👍

A proper 8 bit DAC is an amazing feature for such a small micro, ordered a few to play with.

Honestly, I never have a clue what Ben is talking about or doing when it comes to any of the tech stuff he works on but he's still one of my favorite RU-vidrs just because of his personality, been subscribed for nearly a year now and I watch most of his vids just for his sense of humor and all the random hysterical things he says while he's working

I have to say Atmel Start seems pretty cool. Nice way to lower the learning curve and get people started with all the features. I also imagine it must have been pretty fun to build it. :)

I really appreciate that Ben is not afraid to get his hands dirty, and doesn't assume that we are all 1st graders, because frankly I'm sick to death of seeing 'hello world' and 'blinky' tutorials with no followup. On this note, the ATTinys are a great fit, because they kind of force you to use the old grey matter in order to get them to do anything useful.

Interesting! After using AVR's for my first few years in microcontrollers, I grew tired of their limitations and got into STM32, never looked back. If it is a must to solder one without a hot air station, I know there are some STM32s in SO8 and TSSOP14/20 packages, but to be absolutely fair - these particular parts don't contain DACs. But once you get into QFN packaged parts, it's like night and day in performance and peripherals plus they can get really small where it matters. I love that Single Wire Debug works on any STM32 with a $5 dongle I can get from mostly anywhere, Microchip used to price their not-so-great programmer way higher.

Ben Heck's getting equipment from manufacturers again! This is an absolute win!

Thanks for an excellent intro to this microcontroller family. I'm looking forward to your follow-on video(s).

I've been bare metal programming the atmega chips for years now. I recently decided to try the stm32 but thought it was a bit complicated for me, so I bought a AVR128DA48 and this video really helped me figure out my way around the infrastructure. Thanks

I love this microcontroller videos, great job!

I probably shouldn't encourage it, but the grandma skit had me rolling.

17:19 Wait, how do you know my grandma? Did YOU program the chip??? You killed my grandma!!

"Please don´t get rid of Atmel Studio" :-D

It's very expensive watching your videos. Every time I do, I end up buying a whole lot of new stuff. This time I didn't even finish your video before placing another AliExpress order. Thanks Ben ;-)

Between you and Steve Burk, good sleeping material. Information, I learn something, and I rest well at night

Would love to see you put that smarmy Aussie in his place and do something with the 3 cent Padauk microcontroller. The world needs to see what someone from America's Canada can do.

8:10 Ben:"We want a division of 0" Ariane 5: "What could possibly happen? ... Go on!" Thanks for presenting these nice little buggers, Mr. Heck:)

Your Canadian accent is like a mix of Canadian, Irish, and an old Amish man.

That's not a sine of life, it is a square wave of life!

Thanks for the introduction to Culvers! I am now addicted to the fries!

Your indent style is the only one which should be acceptable! Thank's for pointing me to these new devices - I had no idea that they had launched a new series of ATtinys as well. I'll need to get some myself...

Wow... 9 minutes. A new PB!

There better be cooking!

50:09 I much prefer datasheets that over explain the shit out of how it works as I have encountered datasheets that don't and it's a true nightmare to figure out. Like for example the W5100 Datasheet was not entirely clear that you cannot just set the index to how many bytes you wrote to memory. Instead you must first read the index, send the data starting at that index then add how many bytes you wrote to the index and write it back to the chip. You also have to detect if you have overflowed the page and if so wrap the data accordingly and calculate the index to the end of the page then add the rest of the value to the base page address.

Hi, I would love to watch an in-depth guide/tutorial by you on these tinyAVR 1-series MCU's using both Atmel Studio and Atmel Start. Thanks for this informative video!

100% agree that hunchback is the best disney movie. My all time favorite glad to see ben has good taste

nice to see someone else who uses the microntroller part number when creating a project name

And the Oscar goes to ... Ben

Liked and sub'd, been watching a heck of a time.

Hi Ben, great video, Master of Microchip ATMEL, you can add other videos of this small and powerful microcontroller, also detail the tools (software and hardware) and codes used to start testing, unfortunately I still do not have the integrated one physically. Greetings.

I heard the this new C89 thing has stuff like preprocessor defines and bit shifts so you don't have to put hand crafted hex values all over the place.

Praise be to Jeebus. Comments keep Ben's algorithm a growin'

43:00 Why is the `if (ringBuffer[txPointer]) { transmitByte(); ` portion required for the `uartSend()` function? The datasheet explicitly states that "DREIF is set after a reset to indicate that the Transmitter is ready" in section 24.5.5, so you don't actually need to have ever written to `USART0.TXDATAL` in order for the DRE interrupt to fire. By my reading, just setting `USART0.CTRLA |= USART_DREIE_bm;` _should_ immediately trigger the interrupt to run at that point if appropriate, which already performs that exact check first thing. The way this peripheral is meant to be used, you're supposed to just set DREIE any time you add a character to the send buffer, and then just immediately have the ISR pick the character back out of the buffer with zero delay if it's ready to send. And while that does end up shuffling that first character into an intermediate buffer one extra time even though you could've written it directly, that is actually *more efficient* than shuffling around all the data you need to even _check_ whether or not you need to. Here's how I'd do it: (EDIT: incorporated fix from @Mark S ) ``` #define BUF_POWER 5 #define BUF_SIZE (1

GIMME DA SCOPE, oh wait, wrong channel...

Add an RC high-pass filter to the DAC's out and it will be cleaner.

"good artists copy; great artists steal"...Jobs was quoting Pablo Picasso :-)

At last! A low pin count micro with serial peripherals! Better late than never I suppose? Always puzzled me why they did not do this for making distributed individual sensors or actuators controlled by serial bus. Hook this up to a single microswitch and then wire your machine using I2C, or another serial bus.

This was like listening to Charlie Brown's teacher saying "wah-WAH-wah" except with occasional pop culture references. Still interesting though!

I guess from the praise for UPDI you haven't used debugWire. You could already program using only one wire, though from a quick glance maybe updi is faster. Debugwire wasn't on high end chips, it was on low pin count chips, including the attiny25 you were comparing to.

Thanx i'm a noob on the microcontrollers world and this video is useful

Like you, I'm taking a stab at the ATTINY88. Got most of it to work somewhat, Using the Arduino IDE. I haven't tried Micro chip stuff yet. My show stopper so far is no RX/TX functions. Blink works, servos work, ect. . It also has no PORT id, and resets wildly with some Nano sketches.

Hi Could you explain and show the programming interface you used -thanks

Thanks for the video, I'm not sure if I remember this right, but can't you Ctrl+Click on a variable or define to get to the definition ? Maybe not :) It's been a long time but I hope to get back to this kind of stuff soon! I made a little 3 button controller with an ATTiny85 for my monitor which would let you select VGA/DVI/HDMI without going through the menu by simulating button presses. Just as I was about to get the timing perfectly right, I somehow lost the code, but it still works most of the time.

Nice Dave Jones impersonation, I hope we get to see a Ben's impersonation 😂

2:42 - You happen to be the world's foremost rockstar electronicist.

35:38 I like the bracket there :)

I read it as Techno-Blog-y

😭😭😭 I cry, when I see delay() in interrupts

Every once in a while I know what he's taking about. It's at those times I feel smart, but two seconds later I'm right back to feeling dumb again.

We need a spinoff show. Ben's Grandmama

I love the reference at 3:15 ... those who know :)

what about making an attiny synth?

This was a fun one always tossing in random stuff fun listen.

What's the name of the tool you used at 14:40 to generate the wave signal as an array? Great video! I love seeing the process of going through the datasheet and figuring out how the MCU works.

26:07 We come for the tech, we stay for the silly Disney parodies hahahahaha :-D EDIT: 30:55 We also stay for the funny Canadian impressions hahaha, sounds like some sort of Aussie pirate that lived in rural Canada for a few years hahahahaha!

HAHAHA Sams choice I2C love it!

AAAAAA { on the same line as the while... O M G !!! Ben Hack indeed

nice tip: analogx pcalc (search it, it's free), it lets you put in c expressions for hex/bit manipulation. Other than my gcc, this is the most used tool on my machine. (doesn't contain adware/bulls*, I have no relation to the author whatsoever - but I can imagine he's a great dude!)

Wow! The chips themselves are nice and affordable, but that ATMEL ICE is a bit of a gouge!

A.W.F.U.L.

@4:54 that's a square wave of life, not a sine.

Unfortunately, there is no Linux version of Atmel Studio. There is an Eclipse plugin, but Eclipse has shown itself to be unreliable on my machines.

I got started with atmel

“Nice hiss!”

hmm I guess I could ask here, but I doubt I'll get a response. Anyone have any idea how I could control a 34v-ish motor from something like a raspberry pi or arduino?

4:55 "Looks like we have a sine of life" Looks more like a square (wave) of life to me ;)

Quick question: I have some ATTiny412 chips. My Atmel Ice from Atmel Studio 7, is reporting 256 bytes of EEPROM. Also, I notice that Ben, using ATTiny212 chips, is getting a reading of 128 Bytes. HOWEVER, the datasheet (© 2019 Microchip Technology Inc.), clearly shows "64/128B EEPROM" respectively for these controllers. Anyone know why there is a discrepancy? And what the actual value should be?

Steve1989 reference. Nice.

I hope that the ISA is intact, bastard Microchip...

eeeeeeeeeeeeeeeeeeeeeeeeee... I'm with the angels now! lol

Great intro for new ATtiny 1 series. Do you have the code snippets available somewhere?

I wonder what all those squiggly red lines and dropdown list boxes are about? Oh! Another syntax error. How'd that happen?

"I already did a couple tests off camera to make myself look smarter" 😂🤣. And everyone else but they won't admit it.

Did anybody try the fish?

If you're using the free version of AVR Studio and the GCC compiler, you still have to use PROGMEM 😭

I wasn't aware microcontrollers had so many "pereferals"...

Guess I'm here early also man this is cool never knew about this

I dont know why avr 1 series not available in my country, no one buy,no one sell it. Atmega market only for m8,m328p,m128,m2560,t10,t13,t85, ...

Winner winner chicken dinner!!!

That awkward moment when you do a bunch of calculation live on camera and the answer is 69.

was the Canadian guy from Ireland? Nice chip

Can I install linux on ur computer?

Hey Microchip, if you're going to keep Atmel Studio, please PORT IT TO LINUX!! (Or make it work under WINE). MPLAB IDE may suck at the moment, but at least it runs on Linux. You might not have to use 12v programming to recover the reset/updi function if the pin is used for I/O, provided the fuse isn't the ONLY way to get pin io function. Not sure if the pin mux can override the fuses on that one. I've started fooling with the atmegaAVR128 series processors. They are similar to the new tiny series (Xmega / ARM CortexM derived). BTW Ben, can you put your code from this video up on Github or someplace? I'd like to steal (I mean BORROW) some of it. Thanks!

RRRripper!! Thx!! ;-)

Tiny84 and Tiny85 have debugwire IIRC

Me gusta gutsa

How did you make it so you have Atmel Studio and not Microchip Studio? My Atmel Studio said "hey! I'm Microchip Studio now".

Hmm... 128 bytes RAM and 2K flash... a couple of shift registers, and you've got most of an Atari 2600 console right there... 🤔😁

4:48 Nooo! You said You'll use decimal here!

I'm kind of curious, how much banging your head against the wall trying to figure out weird things do you do? Maybe It wasn't an issue in this project, but what about all of your projects generally speaking? The way you portray your work in video it seems you rarely run into an issue that isn't something you can fix in short order. How often do you spend 15 minutes, 30 minutes, 4 hours trying to figure out why something doesn't work? Maybe that'd be a cool idea for a video.

It is so painful to listen to you, when you have a lump in your throat :-(

hi

I think technoBLOGy. 😁

Techno-BLOG-y.

I’m a master butcher and an amateur comp geek. Still not offended by your appropriate comment.
