ATmega/ATtiny Microcontroller Programming Shield for Arduino As ISP R1

ATmega/ATtiny Microcontroller Programming Shield for Arduino As ISP R1

 

I like using ATmega/ATtiny microcontrollers for my projects.

I normally use Arduino IDE and Arduino As ISP to program them.

I built a shield for the programming by myself for my convenience, instead of using a breadboard or other products.

This is my “ATmega/ATtiny Microcontroller Programming Shield for Arduino As ISP R1”.

I’ve been using it for quite long time with no issue but I’ve recently felt that should be enhanced a bit.

I’ve just started working on building “ATmega/ATtiny Microcontroller Programming Shield for Arduino As ISP R2” with following enhancements.

 

  1. Support ATmega8535/16/32/164/324/644/1284 DIP40 microcontrollers.
  2. Support ATtiny261/461/861 DIP20N microcontrollers.
  3. Add a power switch.
  4. Adopt a PCB with a standard Arduino UNO shield formfactor to make it look better.
  5. Make the status LEDs - Heartbeat, Error & Programming - brighter.

 

I’ll post the details about R2 including the circuit diagram, PCB design, BOM & etc. when they are ready.

  • I would quite like to use the ATtiny85 chip and I have been buying the parts to make a programme for some time, but I have never got around to putting it all together. Your R1 version looks interesting, are there more details around somewhere?

    Please understand that my R1(R2 as well) is not a standalone programmer.

    It is just a shield works with Arduino and I'm using an "Arduino as ISP" as the programmer which is the Arduino running a sketch(program) called “ArduinoISP”.

    You need to add "http://drazzy.com/package_drazzy.com_index.json" to “Additional Boards Manager URLs” of your Arduino IDE and install “ATTinyCore by Spence Konde” to be able to program ATtiny series microcontrollers with it.

     

    Building a shield to program ATtiny85 is quite simple.

     

    • RESET(PIN1) of Attiny85 -> SS(PIN10) of Arduino.
    • GND(PIN4) of Attiny85 -> GND of Arduino.
    • MOSI(PIN5) of Attiny85 -> MOSI(PIN11) of Arduino.
    • MISO(PIN6) of Attiny85 -> MISO(PIN12) of Arduino.
    • SCK(PIN7) of Attiny85 -> SCK(PIN13) or Arduino.
    • VCC(PIN8) of Attiny85 -> VCC(5V or 3.3V) of Arduino.
    • 0.1uf ceramic capacitor connected between VCC(PIN8) and GND(PIN4) pins of Attiny85, as close to the part as practical.
    • 10k resistor between RESET(PIN1) and GND(PIN4) of Attiny85.
    • 0.1~10uF capacitor between RESET and GND of Arduino. (I use 10uF.)
