Uploading arduino bootloader

  • Upload the ArduinoISP sketch into your arduino board

The setting of the LEDs from left to right are:

LEDs Description Status
D7 Programming when IC is programming properly
D8 Error when target IC is not connecting properly
D9 Status: heartbeat keep beating when power up
  • Button Press for D10 to LOW TTL

Setup the shield

Flash Bootloader Programming Guide and Note

  • Support three attiny series
  • Some version of ArduinoIDE is not working well, for example, 1.61, 1.00, etc, better version approved 1.05, 1.56-r2
  • Burn bootloader twice, sometimes it seems the arduinoIDE bug: the IC will fail on uploading sketch when moved to arduino board
Series DIP setup group Auto-rest ATtiny2313 jumper Core file supported 1.5 IDE LED
ATtiny13/25/45/85/2313/4313 1st group up-off Down-off and On-up for attiny*313 LinkSource D3
ATtiny24/44/84 2nd group up-off Down-off Link
ATmega168/328 3rd group up-off Down-off default in IDE Digital pin 1 (D1)
  • Done!

Board setup

  • Set the auto-reset to off, now you will only program the target IC
  • Set the right jumpers for ICs, see the examples below, ONLY turn on one group of toggle switch every time.

Programming from PC

Upload blink sketch for testing

  • To check the bootloader, you can try upload sketch
  • To upload sketch to the IC on the shield, choose "upload using programmer" in the menu, otherwise it will upload into arduino main board
  • or using avrdudess to upload AVR hex file
  • Do not program the LED pin 13, then LED on the shield will not work, use following settings instead

Series Blink sketch for testing LED on shield
ATtiny13/25/45/85/2313/4313 int led = 4; (attiny13, etc), int led = 1;(attiny2313, etc)
ATtiny24/44/84 ?
ATmega168/328 int led = 1;
