Link to circuit diagrams & assembly code: akuzechie.blogspot.com/2022/0... Link to tutorial for programming ATtiny85 with Arduino Uno as ISP: create.arduino.cc/projecthub/...
I have watched many similar tutorials and I still do not understand why it is necessary to burn a bootloader into the ATtiny. Why not simply burn the hex file directly? There is so little code space in the ATtiny13A for example that it seems wasteful to use any for a bootloader.
@@AnasKuzechie I have investigated this further. Regular Arduino boards using the bigger micros like the 328 do use some 500 bytes or so of code space for a boot loader. However, the Tiny range, when programmed by an Arduino as ISP, do not use a bootloader. The so called Arduino bootloader in this case just sets the fuzes to set clock speed for example but does not load any code into the Tiny. Basically your hex file goes straight in and all the code space is available.

This channel has got to be one of the hidden gems of TH-cam, thank you
Thanks John
Definitely, He is a 'RARE' GEM.💐🌹🥰🎉
@@IMRANKHAN-we9un thank you
as always - thank you for sharing your knowledge!
great video! waiting for more
Thanks. You can checkout my other ATtiny85 projects.
This is amazing, it appeared on my recommended, it would be great having this amount of views lol
Thanks for your feedback
Thanks
Can push buttons be connected to the tm16xx integrated circuit?
Yes, but not with the display module I demonstrated. You have to get the TM1637 IC and interface to it the buttons. You can check the datasheet.
when i uplode code show ( errpr: A programmer is required to upload ).how to solve it
Same issue, did you resolve it yet? If yes please let me know

I believe Arduino IDE loads the hex code via the onboard bootloader. I use assembly to optimize memory storage.

@@ruffrecords Thanks for the info
