- 1. How to set Attiny202 Tanno Yoshinobu
- 2. Attiny202 is Small Microcontroller Reference https://akizukidenshi.com/catalog/g/g115731/
- 3. Environment for set Attiny202 Software Windows 11 Pro Arduino IDE 2.3.2 Hardware DIP8 Programmer Adapter Socket Converter Module 150mil Arduino Duemilanove Some Wires and 4.7kΩresistance and Breadboard LED
- 4. Procedure 1. Make Writer 2. Install MegaAttinyCore in Arduino BOARDS MANAGER 3. Connect Arduino Duemilanove and Attiny202 4. Burn bootloader 5. Embed Program
- 5. Make Writer • Download and Unzip https://github.com/SpenceKonde/jtag2updi • Rename Folder Name “jtag2updi” • Open the jtag2updi.ino with Arduino IDE • Click Upload Button in Arudino IDE
- 6. Install megaTinyCore in Arduino BOARDS MANAGER • Arudino IDE Tab -> File -> Preferences -> Additional Boards Manager URLs -> http://drazzy.com/package_drazzy.com_index.json • Arduino IDE Tab -> Tools -> Board -> Boards Manager -> install megaTinyCore
- 7. Connect Arduino Duemilanove and Attiny202 • Set Attiny202 in DIP8 Programmer Adapter Socket • 5v in Arduino Duemilanove <-> VCC in Attiny202 • GND in Arduino Duemilanove <-> GND in Attiny202 • Digital Pin 6 in Arduino Duemilanove <-4.7kΩ-> UPDI in Attiny202
- 8. Burn bootloader • Arduino Tab -> Tools -> Board -> megaTinyCore -> Attiny412/402/212/202 • Arduino Tab -> Tools -> Chip -> Attiny212 • (option) Arduino Tab - > Tools -> Internal Clock and so on • Arudino Tab -> Tools -> Programmer -> jtag2updi(megaTinyCore) • Arudino Tab -> Tools -> Burn Bootloader
- 9. Embed Program • Arduino Tab -> Sketch -> Uploading Using Programmer • Wire Led between pin 4 and GND ( and resistance ) • Sample Code void setup() { pinMode(4, OUTPUT); } void loop() { digitalWrite(4, HIGH); delay(1000); digitalWrite(4, LOW); delay(1000); }
