Yo. You should make a tutorial on how to design a bootloader in the form of an Arduino Shield...

@gameboys248 5 лет назад

I have one guestion. How about 328P in smd version is it same connections as in your tutoril arduino bare minimum or there is diference.

@user-uv2gu8wm6h 4 года назад

arduino ide always stuck at uploading while uploading blink to my atmega8

@KennethScharf 5 лет назад

The atmega88 is the newer version of the meg8. It's a better chip having more interrupt lines, and it works up to 20mhz vs 16mhz for the '8'. The mega8 might be cheaper, especially in surplus. BTW you CAN use the USBISP to program the optiloader on the chip. I've done it! (Via the command line with avrdude)

@alexandrebaux4042 5 лет назад

Thanks a lot for this tutorial

@InputBlackBoxOutput 5 лет назад

Very informative video Just a question. Do I have to always use a FTDI chip based programmer to program the ic or can I just replace the ic present on my uno permanently.

This video is 4 years old, yet is more useful than anything around recently. Thanks man! Exactly what I was searching when hitting a brick wall with my atmega32u chip (this one in particular are the ones Leonardo boards uses)

@ZulfiqarAadil 4 года назад

I do as you describe and its work but I observe very important thing the "startup delay THE INBUILT LED BLINK 3 TIMES IN A SECOND THEN OFF FOR TWO SECONDS " so total about 3~4 second startup delay and how to get rid of it ?

@TooSlowTube 9 месяцев назад

The ATmega8 vs ATmegaXX8 table you've shown seems to show 2 SPI interfaces, for most of the chips listed, including the 328P. That's wrong, isn't it? The Uno has two sets of pins connected to SPI (the 6 pin ISP and some of the D pins), but they're just wired together, aren't they? I now realise how difficult it is to get a decent high resolution schematic of the Uno, as an image. I'd saved several, over the years, but they're mostly too blurry to actually read properly.

@addiction-69 5 лет назад

Why you didn't make a video on program to pic Microcontroller easily like you did on Atmega8A or Atmega 328.

I was about yeet my chip across the room until your video saved it.

@wachannel7082 4 года назад

@YugoZex 2 года назад

I bought Atmega8 16pu and I have a question? Can I use another arduino Uno and put this chip in instead of 328 and to burn bootloader that way, using 2 arduino uno's?

@confusedengineer7424 5 лет назад

nice video

@ravivashatkar5585 5 лет назад

Good one

@paulspark7287 29 дней назад

There's definitely a gap in the explanation of configuring the FTDI board to load the chip on the breadboard. I've tried uploading blink to the COM port of my FTDI programmer and I'm seeing "avrdude warning: attempt 1 of 10: not in sync". I have no idea what the loading baudrate is supposed to be?

@ram_creativan 2 года назад

please make a video example of a simple tft lcd program using an atmega 16 chip.

@hugowoesthuis 5 лет назад

I would like to see an AVR programming troubleshoot video. I have multiple chips that get DID 0x000000 for some reason, preventing from programming them. I simply can't find the right solution

@MaxintRD 5 лет назад

The chips maybe locked. Some cheap suppliers sell pre-burned chips. A high voltage programmer may allow you to reset the fusebits. They could alse be fakes. See the video on my channel for more about that...

@edelweishurt2059 2 года назад

Is it possible to display characters with a 16X2 I2C LCD?

@mikelor84 5 лет назад

Great video! It was very useful. But I have a question: how did you chose a 10kohm pull up resistor for the reset pin? why that value? I'm trying to learn how to calculate the right size for pull up/down resistors for logic CMOS digital circuits

@thebluemarauder 5 лет назад

10k is pretty much the default value for pull-ups and pull-downs. There isn't any precise value or formula to follow, pretty much anything from around 4.7k to 22k, maybe higher, will do. 10k just tends to be a value in that range that most people have on hand most of the time, so it kind of feeds back on itself and everyone just uses them by default and keeps them handy whenever a pull-up is needed. Pretty much the idea is to be a large enough resistance to be easily overridden by a connection to the other rail while being small enough that there will be enough current to maintain the desired input level. In general unless a datasheet specifies a different value, just assume 10k will do.

@mikelor84 5 лет назад

thank you very much

@michaelward402 2 года назад

Too big a resistor can lead to noise problems where the current is so small that the gate can be affected by power supply noise. Too low a value resistor can lead to latching, where something trying to pull the line high or low cannot overcome the current, because of device limitations. So this is very dependent on what is attached to a gate. in general, anything between 4K7 and 10K should suffice.

@mikelor84 2 года назад

Is possible do this without the 16Mhz Xtal, using only 8MHz internal oscillator ?

@turutzi 5 лет назад

Nice Video But litte "fun fact" you could allready use an atmega8 whit the basic board libarry. Under the "arduino NG" bord you coud choose between a atmega8 oder atmega168. So theoretical you dont have to add new boards to your libarry but still nice to have.

@ELECTRONOOBS 5 лет назад

Thanks. I've tried that and for some reason didn't work...

@TooSlowTube 9 месяцев назад

Where does that atmega8 vs atmegaxx8 table come from? It would be nice to be able to read it properly, instead of just being shown glimpses of it, or being shown it all but at too low a resolution to read it.

@rafaelcabelo6616 5 лет назад

Atmega16? Stepping back. I do recommend to get Atmega168 for projects that don’t need more than 16K of flash and Atmega32A that is more chipper than Atmega328. Try to use STM8S instead Atmega8. You will love it.

@tunahankaratay1523 5 лет назад

Of course the atmega16 and those pics would be interesting. I can't find any good tutorial about the PIC MCUs.

@DavidFromMars 10 месяцев назад

Why do you need to connect all those components to the microcontroller between programming it with Arduino?
