Those new attinys are really nice, especially with the UPDI.

[@Mr.Leeroy]

They like added some of essential features missing all those years and boom.. 'modern' Attiny fam. And all I can really call them is 'not as legacy' as classic ones are now. I swear people still use them in new designs mostly out of habit inertia, they are so not competitive in modern days..

[@brettb.345]

Yes, but to me the 8-bit architecture makes them more efficient in many ways. They can do a lot with less than newer "more powerful" chips. The instruction set can do more in less space.

[@Tomek-i3g]

@@Mr.Leeroy No, ATMELs were really neat designed. I always wrote and still writing in pure assembler on those chips and on ASM you can really see difference when it is well designed or not... So it was very capitalistic when worse firm Microchip acquirered better firm ATMEL . In american Capitalism always worse winning.

[@Tomek-i3g]

@@brettb.345 True, I wrote whole operational system in 8KB for ATMEGA8. ATMELs are 5 times more efficient comparing to INTELs 32bit 80x86.

Merci, very interesting.

What is the USB UART adaptor board you show at 10:00? I like it. All the IC pins are accessible on pin headers.

Hi can you make a video for diy Impedance synthesizer using opamp and some standard resistance and capacitor.

[@ralphj4012]

A resistor between TXD and RXD on the FTDI adaptor seems odd (to me), some sort of feedback for the 1-wire?

[@jyvben1520]

or it protects both pins from overcurrent, SerialUPDI is a UPDI upload tool which uses a normal USB serial adapter with the most trivial of modifications directly as a UPDI programmer.

[@Tomek-i3g]

It can help to match transmission line when speeds are high.

[@IMSAIGuy]

because you have two transmitting devices on the same wire

[@ralphj4012]

@@IMSAIGuy Aha, a naff anti-contention, receive-steering thingy. I'm surprised it's reliable.

[@IMSAIGuy]

@@ralphj4012 you can also add a diode, but the resistor works fine for me

[@rolandkamp5307]

Are you using 3.3V from the uart board? Using 5V can damage the oled display?

[@IMSAIGuy]

Yes. Using 3 volts the digital cap is limited to that.

[@Tomek-i3g]

What is funny, often these small microcontrollers really have bigger flash, because it is no difference in cost to make 128KB flash or 1KB flash but those greedy american Capitalists just switch off flash in small microcontrollers by software means during production...

[@MartinScherpa]

could you take a look on stm boards? i have been working on the blackpill model (Stm32f411) and i think it's pretty cool for all the things that it offers. a lot of communication protocols and for peripherals, it can do digital sound processing and fft

[@IMSAIGuy]

yes the STM32 products are very powerful. I never liked the blue pill board though. I do like the STM32 devboard and derivatives. I don't enjoy software so I tend to avoid processing type projects. the tinyAVR fits my needs of a small cheap do it all part.

[@gorak9000]

Is ATtiny really considered a 'modern' part? They've been around for quite a while. Not saying it isn't a good choice for this project, but I bet they don't get used much now - not enough CPU horsepower for "AI", and to connect to the cloud to steal and sell all your data

[@IMSAIGuy]

it is 7 years old. That is modern in my book. this is the tinyAVR series 1
