Today I happened upon this ATTiny85 Quick Reference.

MPLAB® X Integrated Development Environment (IDE)
My mate @gwozniak recommended I check out MPLAB® X Integrated Development Environment (IDE) for programming my ATtiny85 microcontrollers. Gonna try to get around to that soon.
ATtiny85
These are some notes I made about the pin-out of the HW-260 adapter boards I have for my ATtiny85 microcontrollers. I think my ATtiny45’s are also compatible. Not sure about my ATtiny13A’s.
ATtiny85
Found myself reading about the ATtiny85 again. I keep coming back to this one. It’s an old favourite.
TIS-100 PoC
So not sure if I’ve mentioned TIS-100 on the blog before or not (update: I have). But it’s this neat computer game where you need to program a network of devices (the “Tessellated Information System”) in a pseudo assembly language in order to make a broader information system work. Anyway I was thinking about doing a hardware implementation of the system and using either some type of ATtiny (probably an ATtiny85, maybe an ATtiny45) or maybe an Arduino Nano. I did a mockup with an OLED display using a nano:
ATTINY85
Searching for ATTINY85 over on AliExpress and sorting by popularity renders some interesting results.
SparkFun Tiny AVR Programmer PGM-11801
I have one of these: SparkFun Tiny AVR Programmer PGM-11801. I was thinking of getting another one or two for backup, but there’s probably no need at the moment.
Also I figured out how to put a programmer on my Pluggable ATTINY Development Board For ATtiny13A/ATtiny25/ATtiny45/ATtiny85 Programming Editor Micro Usb Power Connector (see that link for details).
Apollo Guidance Computer
Reading about the Apollo Guidance Computer. Compare that to the US$3.23 ATtiny85.
| Spec | AGC | ATtiny85 |
|---|---|---|
| Word size | 16-bit | 8-bit |
| Clock | 2 MHz | 20 MHz |
| ROM | 72 KiB | 8 KiB |
| RAM | 4,096 B | 512 B |
The values in the above table are approximate, see the sources listed above for actual figures. Basically the $3 chip is ten times faster than the AGC but with less storage. Call it a draw?
