rpi

My Arduino, ATTiny85, ESP8266/32 and RPi (Raspberry Pi) projects

Reference information:

• ATTiny85
• ESP8266
• esp-wroom
• GPIO-pi3: pin diagram for RPi3.
• i2c: Arduino and RPi3 master, ATTiny85 slave
• i2s
• spi

Arduino Nano/Uno

• IDE : general setup, particularly about ATTiny85 setup.
• sketch_feb05a : RTC clock + zeroseg (0seg) to create a digital clock

General

• debounce a button
• picocom
• Twiddle-factor FFT for mcus

Projects

• 0clock: clock made with nano, 0seg, and tiny RTC.
• abaclock: clock made with a RTC clock and an Arduino LED backpack
• alacrity: pills reminder and warnings raised by alarm
• alarm: raises a panic call to alacrity
• atlast: a Forth for mcus based on Walker's Forth
• blinky85: directory containing code for blinking an ATTiny85 from RPi - consider it a baseline for making projects using C++, and not the IDE
• blinkt.
• clockesp IN PROGRESS
• dev01: meditation timer
• dev02: projects for the DEV02 home-made board: green_red and mhz85
• dev04: Programming an ATTiny85 from the Pi
• dev05: ATTiny85 programmer for the Pi
• dev06: 8x8, nano
• minitone85: working version of tone() for ATtiny85
• mins30-85: 30 minute timer for ATTiny85, programmable from the Pi (DEV01).
• pills: remember to take your pills
• synth: sound synthesizer/tone-maker
• sleep85: conserving power by putting the ATTiny85 to sleep

Hardware

• Enclosures 10pcs 75 x 54 x 27mm DIY Plastic Project Housing Electronic Junction Case Power Supply Box
• Mini USB nano. Amazon also has good deals on these
