I have told everybody I know about this 3 cent chip, these are some of the best EeVBlog videos yet. #KeepupthegreatworkDave

This is the best EEVblog video i have seen. So much nicer than bagging other peoples work.

AVR GCC is actually pretty good at optimizing for really small microcontrollers. For the ATTiny 10 you can a lot of the stuff without even using its 32 BYTES(!) of SRAM, all with C.

sounds about as powerful as the Zilog Z8 from 1998. We used the comparitor with a slope generator to do a ADC. We used it in the Turtle AMR meter reader. Which interestingly has the longest distance record for sending signals over the power line since there was one in the Australian outback. It was a 2K program written in assembly to save space. You can save code space in assembly by making subroutines with multiple entry points.

I reckon it is fair that a company that took time to design and produce a ICE and programmer doesn't want to open source it.
$100 isn't all that much. The pickit isn't much cheaper.

I did my electronics (comms) apprenticeship starting in '80. In '79 calculators were still banned at my school!
I didn't use a computer (started on PDP7 and 9 at work in '90!) until Win 3.0 in about '95..
To see the functionality in such tiny chip packages at such negligible cost just staggers me.

I am impressed. A tiny little package that contains so much and can do a lot.

Wow dave... You really have unleashed a monster here... People seem to be so engaged...

Awesome. Should be possible to program these chips with other programming hardware. Voltages isn't a problem. It's limited how much code is pushed into that little bugger anyway. Dave, care to do a poor-mans decap on one of those? Just torch it with a gas flame, clean the resulting die in acetone and let's see it under the microscope.

Thank you so much Dave! I’m so excited about these!
Suggestion: Use it to run Ws2812b’s!
Can’t wait for more!

would love to see a reverse engineered programmer for these chips

OTP not for the hobbyist market... these things are for disposable electronics like greeting cards. Amazing the job they've done with the IDE etc... thanks for the demo!

SDCC (Small Device C Compiler) would be a good compiler for the chip.

Cost of the programmer and ICE is reasonable. Glad you've done the reviews.

Thanks for exploring these low cost chips, they ended up providing me just the solution I needed!

Its nice to see a manufacturer that is interested in helping developers. I recently purchased a programmer which cost over £2000.00 and it could not program some devices without and (expensive) adaptor simply because the pin out was different even thought the programming algorithm was the same. I asked them why they did not allow users to create custom package files to define pins and they said it could not be done. I think they meant that they could not charge users £500.00 for adaptors if they could do it.

I'm imagining this reading I2C and outputting servo PWM control so you could reduce wiring in more complex RC devices by just running busses.

Great video! With that retro ass UI I was half expecting the programmer to use a parallel port!

sdcc (small device c compiler, instead of gcc) is the open-source solution for several types of microcontroller architectures (8051, z80, pic, stm8, et al)

While Padauk may sounds esoteric to DIYers, it is very well known among mcu hardware professionals in China and SEA. Billions of chips made by Padauk are used in toys and small consumer electronics, where power consumption and cost are primary concerns. Some devices may contain more than one such MCUs.
