Hey all,
I hope you like the video. It's a little different of a format than i normally do because i had limited time to make it and doing it this way is faster than doing a voice over.
Let me know what you think either way!
I didn't even notice any difference with it apparently not being a voice over. :) Perhaps since you're so practiced at live streaming it's just natural to record live instead of doing a voice over? Great little tutorial! :)
If you wouldn’t have told us I wouldn’t have noticed the difference. Maybe some mouse clicks are hearable (you maybe starting or stopping the record with it?) but if this is a faster way to produce videos, go for it Brian. I know how limited time is if one has a family....
BTW interesting chip. Maybe an alternative to our Attiny 85, if there just was a dip version of it. As you know I’m an old style trough hole fan....
You voiced that as you recorded it‽ It was so polished I just assumed it was a voice over. Great video - would love to see one going through what the 841 can do.
Thanks for the walk though and references.
One tip for anyone getting an USB to serial converter like the one mentioned at 9:25; try to get one that has the "DTR" pin broken out on the output pin header. This is one of the signals on the converter chip. "DTR" is one wire of the whole RS232 serial communication standard these chips are designed for. When programming many other Arduinos over UART the automatic reset over USB is handled using the DTR pin.
If you're ever looking to make your own boards with one of these converter chips the ch340g's are cheap and the SOIC package is much easier to play with. Also, the translated English datasheet has a schematic example of an optocoupler isolated design too. This can save your computer if you happen to have a dumb moment on the bench or experience a bad failure.
Lastly, when using the USBasp's they always produced an error message that makes it appear as though they are not working when infact they are. They kinda suck with the ArdyIDE. They work far better from a command line using AVRdude although I have gotten both to work.
I'm no expert. This has just been my experience on the subject.
As a simple viewer, I definitely prefer these types of general reference uploads that are easy to save in a playlist and reference later when I need them.
Thanks again,
-Jake
I have some of the newer AVRs at home, but didn't look into programming them yet - glad you made this video! :)
Great job Brian! I really like this "introduction" approach. Keep up the great work.
Nice video Brian! This one pushed me over the edge to start experimenting with little chips like this. Thanks!
Excellent video, Brian. I look forward to seeing a video using the 841 as an I2C slave. I can see this as valuable, enabling makers to build their own peripherals/sensors ; perhaps with some processing to free the master mcu for scheduling. This was the first of your videos that I have viewed. You have a great channel here.
Very nice! I enjoy learning about the different chips and their capabilities. The 2 hardware UARTs on this chip could be really useful for certain projects.
This format is great...I would like to see more chips that can be programmed like this …..more please !.....basically this becomes an invaluable reference tool.
Very helpful, thanks for posting.
This was a cool concept , having the IC. Center stage!
Thanks for the info, very well explained. Looking forward for more projects with the ATtiny
841.
Cheers!
Hah! Perfect! A new trendsetter maybe. Finally a video that mentions all the traps you can fall into. Thanks for the stream, I couldn’t stay for it all but this is GOLD for many - a no BS how-to with all the pain removed (but nevertheless we can still feel it - lol). More please! 😀
A great overview video Brian, much better condensed than the long stream getting it to work!
What you mean you don't want to watch me fumble around trying to get it work for 3 hours?!
@@BrianLough .... that's what she said!! 😂
@@ChunkySteveo 3 hours, you flatter me 😎
Another great video. Thanks. And congratulations to you and your wife, on expecting baby #2.
Awesome mate , Great video and clear explanation helpful valued Thanks
Just found you via Seon - enjoying the vids 😃
you helped a lot! thanks
You have the knack of distilling information down to the most important points.
Don't worry about voiceover. Have you noticed that the audio of my recent videos are littered with cat meows? See? nobody notices :-)
Thanks for this video. Great content, great presentation. I will order some ATTiny841.
Thanks for help
Great follow-up video!
Cheers Seon!
if you put the chip at the other end of the adapter board the two extra pins could be used for a decoupling capacitor solder bridged to pin 1 and 14
Hi Brian, really useful video, many thanks. Do you know if this chip can do the 'secret voltmeter' trick of measuring it's own voltage like the atmega328p can? I've looked through the data sheet and I'm still not sure. Electronics beginner here.
Brian, excellent video, I was trying to program an attiny861 but been getting Device Signature 0x00000000 error. I wondered if you ran into a situation like that. I have been searching the google and lot talk about the attiny85 chip. not the attiny841 ir attiny861 chips. Just wondered if you might have some insight on the subject.
Brilliant!
I think powering the wee bugger will be a handful and effectively removing any gains of its small size as you’ll need a 3.3V converter. However nice to know it comes in such tiny packages!
According to the data sheet it operates between 1.7 and 5.5v so it's very flexible!
Excellent video. But one remark about connecting the LED to the board.
works with SpenceKonde 1.2.3 board manager release ATTiny 841 pin #6!
works with SpenceKonde 1.4.1 board manager release ATTiny 841 pin #10!
You can use the jumper on the USBASP to set it to a lower speed.
Thanks Brian. Trying to decide between the 841 and the 84. Both seem similar, but the 84 is cheaper through aliexpress. Would the 84 meet your requirements as well?
It's very good video
You can right-click on the cap in Fritzing and select Show Label/Value, that is if you have entered the part's value in Inspector.
I did not know that! Thank you!
How much different in programming space does it take between the arduino asisp to the serial Rx Tx?
Nice interesting video.
Cheers!
Thx
Hi! I would like to know if you have experienced programming several attiny On the i2c or twi bus, like slaves and they can turn on and off a led each with the order from an Arduino UNO as a master, whose function is to send to they the order to turn on and off the led and that the slaves in turn send the status of their leds to the master? Thanks!
I watched a few of the videos. Help me out here when you upload all the things you do. What willit are does it run. I haven't yet found anyone that tells me why they do it.
Cheers. I can't load the jtag2updi program. Please help. Still only when opening, only the base of the program comes out, the other items do not open.
The good thing that it has enough pin for what I need (Si4432, 4 pins for SPI + 2 pins for controls), but bad thing that on eBay, there is no cheap option. Where did you buy this MCU? BTW; you have new subscriber, you did great job. Thanks.
I bought mine of farnell.ie (which is element 14). I know they are available from digikey too. (Both are linked in the description). Yeah that is one pity that it doesn't seem to be available from China
Thanks! Really appreciate it
@@BrianLough Now after looking at datasheet - I like that chip even more. Some things can be done with Attiny85, but sometimes there is need for more pins. Seems that Farnell offer buying minimum of 1 piece, so that is good option too. Not too expensive. Oh, sorry... I did not saw your video description, probably need some more sleep after hours of programming STM32. It will be fun to see both: Attiny841 and STM32F103VET7 together in some communication 'toy' at 433 MHz. Thanks again for great news and really great info.
I'm certainly comfortable with 'chip-based' videos, but I think that some, like thIs one, might benefit from a supplementary video with an example of its use - because it has capability for Slave mode, you can do this...
Does anyone know how to load a hex file into ATTiny841? with or without Arduino?
Why couldn't you use the ch340 uart programmer to burn bootloader as well before uploading sketch. I'm also busy with the attiny841 and have tested both arduino as isp and the ch340. It seems a bit pointless to use the arduino to burn the bootloader and the use the ch340 to upload sketch.
I haven't tried using ch340 to burn bootloader to attiny841 and upload sketch. I'm not sure if it is possible. Have you tried it
Interesting video. I am not sure why you selected the Tiny841, except that you can use the Arduino environment. Other processors has similar data and some is also cheaper. I would choose a processor that can be debugged and that has an professional IDE. It could be a PIC controler where you have an excellent IDE (except for the Crappy free Compiler) and the PicKit debugger probe. My preferred processor in the 8 bit area is EFM8 (ex: EFM8BB10F8G-A-SOIC16R) , it comes with a free IDE (Simplicity Studio) and you can buy an cheap debugger on Ebay (Look for C2 C8051). With this setup you can code and debug (single step and breakpoints). Developing I2C slave will be a lot easier when you can set breakpoints.
The person who makes the i2c rotary encoder also recommend a pic for this job too but to be honest I just dont have the experience yet of working with pics, but there seems to be great info in this post for me to get started so I might PIC up a few... (I'm sorry, could not resist 😂)
I'm pretty time poor at the moment so something with a lower barrier of entry for me is more important than anything else.
Do you have any links for where might be a good place to read more about this stuff? I would actually like to get some of the stuff you mentioned
I know that starting with new stuff has some barrier to overcome, and so its also with micro processors. I did also start with a Tiny (84), I found it very difficult to debug only relying on flashing diodes or serial data. I think if you spend the time with an development environment with a real JTAG,SWD or C2 debugger you wont regret the time spend. So much more in controle.
I started with the PIC processor and a PICKit3 probe (random Ebay: www.ebay.com/itm/PICkit2-PICkit3-PIC-KIT2-3-PIC-Debugger-Programmer-Emulator-Controller-Adapter/263554503372?hash=item3d5d1292cc:m:mF64g1DBKWHXX6A0eNoslbw). From Microchip you can download MPLAB X IDE, which is the IDE. There are some tutorials on the net on how to use it. One problem with the free version of the compiler is that they insert dummy instructions to slow down the code, if you buy the IDE you can get rid of this slow down, that was one of the reasons to drop the PIC.
Silicon Labs EFM8 series is as I said, is my 8bit processor for the moment, the PROS for this processor is: its cheap, the IDE is free and good and the debugger probe is only $10. You can find the processors on Digikey (www.digikey.com/product-detail/en/silicon-labs/EFM8BB10F8G-A-SOIC16R/336-4742-1-ND/8610996) or your favorite place. The IDE can be downloaded from www.silabs.com, and the debugger (random EBay: www.ebay.com/itm/C8051F-MCU-Emulator-U-EC6-USB-Debug-Adapter-Downloader-JTAG-C2-Mode-Cable-New/263210606346?hash=item3d48931f0a:g:YRwAAOSwiKlZvQq1)
Good luck, looking forward to here your opinion on programming microprocessors besides from the arduino types, and using a real IDE and debugger.
ATtiny. A T tiny. A. T. tiny. It's not one word. Thanks for the video, though.
Whenever I have issues with ArduinoAsISP it's cus I've forgotten the cap! :D
Great video but all I get is stk500_recv(): programmer not responding
Get a CH55x chip. It's cheap and fun. No external programmer needed.
Hey Brian, great video tutorial. Thank you for the shout out. I did make the board public in EasyEDA, but perhaps I should try Tindie to offer kits. Your referral helped some viewers to find my channel and subscribe. Thanks! I like the style of this video and admire how you can produce quality video's in short time. I'm still struggling to edit my newest video into something watchable...
The attinys are in fact too expensive. 1 dollar plus an adapter, whereas 1.60 dollar will give you an arduino promini
It's the size aspect. The adapter is used for development purpose, i also use an attiny backed against an minimal nrf24 module as a tiny receiver for toy cars. A promini would not fit
