Getting Started with the tinyAVR 1-series Microcontroller

[@ferrumignis]

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

[@cheaterman49]

Yeaaaah!

[@jeremiefaucher-goulet3365]

[@Dredderick]

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!"

[@NatesRandomVideo]

That one surprised me. And I liked it! LOL

[@MichalKobuszewski]

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.

[@xp7575]

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 KZbinrs 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

[@chain3519]

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

[@kadlerio]

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. :)

[@RanHam]

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

[@YoutubeBorkedMyOldHandle_why]

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.

[@alejandroperez5368]

You sure about that? You can use the Arduino framework with them.

[@AJMansfield1]

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

[@ax13h]

As written you've got a race condition in putc. WritePointer will actually load increment and store before ch is writen to the buffer. writePointer++ needs to be on the subsequent line.

[@AJMansfield1]

@@ax13h Oh, good catch. Technically, before C++17 the update to `writePointer` and the write to the buffer were actually just unsequenced (which still isn't good), but yeah, since C++17, `writePointer` gets updated first: "17) In a subscript expression E1[E2], every value computation and side-effect of E1 is sequenced before every value computation and side effect of E2" (from en.cppreference.com/w/cpp/language/eval_order#:~:text=In%20a%20subscript%20expression )

[@donpalmera]

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.

[@exosdel]

I love this microcontroller videos, great job!

[@DouglasFish]

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

[@MrDaniellong1970]

Wow... 9 minutes. A new PB!

[@BusyElectrons]

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

[@ky5666]

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.

[@Ray-ej3jb]

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

[@planker]

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.

[@stephanemuller7032]

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.

[@poptartmcjelly7054]

what about making an attiny synth?

[@uwezimmermann5427]

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...

[@uwezimmermann5427]

since when "do we not have to do this progmem thing" in AVR GCC using Atmel Studio?

[@0LoneTech]

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.

[@heinzkreutziger2218]

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

[@MikeStavola]

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

[@shivambatra8210]

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!

[@YoutubeBorkedMyOldHandle_why]

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 ;-)

[@BrandonPoulton]

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

[@YoutubeBorkedMyOldHandle_why]

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?

[@BenHeckHacks]

Well there's RAM, flash (the code) and EEPROM. Perhaps you're getting them mixed up?

[@YoutubeBorkedMyOldHandle_why]

@@BenHeckHacks Thanks for the response. I didn't think that I'd make a mistake like this, so I looked again. The ATtiny212/412 datasheet quite clearly states on page 1: Memories - 2/4KB In-system self-programmable Flash Memory - 64/128B EEPROM - 128/256B SRAM .... And for my ATTiny 412s, in the 'Device programmer' window of AtmelStudio7, (read with my Atmel-ICE), the 'Device Information' tab clearly states: Flash size: 4k EEPROM size: 256 bytes SRAM size: 256 bytes I'm inclined to believe the datasheet, though I haven't tried programming the "256 bytes" of EEPROM ... maybe I should.

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.

[@john_hind]

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.

[@JasonPullara]

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?

[@ijaygee1]

Sure, you need an H-Bridge to supply the 34V to the motor and some optocouplers to hook it up to the Pi. You can then use a couple of 3V outputs from the Pi to control the motor direction and, if you use PWM outputs, you can control the speed too.

[@scharkalvin]

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!

[@jody5661]

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.

[@jody5661]

Just to kind of clarify a bit, I'm not talking about coming up with a method on how to complete a project, I'm talking about when you do something that you think should work without an issue but it's not producing the outcome you want. Just a dumb example say you hooked up an 8 pin IC with power on pins four and eight as is common (I could be getting those numbers wrong but I believe I'm not) but it turns out that you're supposed to apply power on say pins one and eight. Again it's a dumb example as I would imagine you would realize that almost instantly but that concept of doing something the way you believe is correct but turns out isn't and you have to go back and figure out why it's not.

[@BenHeckHacks]
