megaTinyCore Alternatives

megaTinyCore reviews and mentions

• SOP Arduino-compatible MCU?
  1 project | /r/arduino | 12 Feb 2023

  They're compatible with Arduino by using the megaTinyCore and programmed with an UPDI programmer. A homemade UPDI programmer can be made with a USB-Serial adaptor and a Schottky diode (instructions on that site).

• Best way to migrate from an arduino-based system to a purely microcontroller-IC one?

  Programming is done via the Arduino IDE, although NOT all libraries work. See: https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/extras/LibraryCompatibility.md

• I got an ATTiny1616 development board. How do I connect the two and flash the code (basic blink example) from the Arduino Nano to the ATTiny1616? Thanks.

  Go check the site for the Arduino megaTinyCore which includes amongst other things instructions on how to make a programmer for that kind of ATTiny microcontroller (the so-called "modern" attinys).

• Interested in a MIDI-capable relay bypass?

  So this megaTinyCore GitHub page talks a lot about the programmers and various ways you can flash to these chips. I basically used 3 male header pins (vcc, gnd, updi) connected to a modified serial programmer that I insert into pads on the board. Crude but honestly pretty painless and effective.

• Used an Atmega328 with Arduino optiboot years ago — is this outdated?

• question about choosing the right microcontroller for a small LED programming job.

  You can program them with Arduino using the MegaTinyCore and you upload programs to it using the UPDI protocol which uses just one wire. You can make a programmer for it with with a Serial-USB Adaptor, a schottky diode and some wires - all the instructions in the link above.

• I need help understanding pin naming notation for bit-bang applications...
  1 project | /r/arduino | 25 Jun 2022

  Yeah, do a quick search for PIN1_bm in this file https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/extras/ioheaders/iotn412.h

• megaTinyCore is missing?

• Cheap ADC / alternatives to ADS1115/ADS1015
  1 project | /r/arduino | 7 Nov 2021

  The modern line up of ATtiny micro controllers is pretty sweet. They go for under a dollar a piece on digikey (best place to get them). They are mostly surface mount so an ebay smd adapter board kit makes them easy to use. I picked the attiny1604 but there are many variations. This is the arduino core for them and if you scroll down has all the info and variation comparison. https://github.com/SpenceKonde/megaTinyCore

• Attiny 1626 Issues with 18B20 temperature sensor
  2 projects | /r/embedded | 3 Nov 2021

  I am programming the Tiny via UPDI through a Arduino Nano using the Arduino IDE with the MegaTinyCore. It does verify the code after upload. I can use a 1306 display (I2C), and manipulate all the GPIO's with no issue. I can use the same GPIO that I have hooked the 18B20 up to for anything else, just not 1-Wire. I have tried other GPIO with the same response. I am using the example for the Dallas Temperature and update the pin assignment. The exact same code works fine on a 328P with the same sensor, so I dont doubt it is a library issue but I'm not experienced enough to figure out exactly where the issue could be.
