Description

TinyBling - it just does bling bling...

TinyBling is a completely pointless device that just does bling bling. It's wasted an ATtiny13A, 16 WS2812-2020 5mA addressable LEDs, and a LIR2032 rechargeable coin cell battery.

Compiling and Uploading the Firmware

Since there is no ICSP header on the board, you have to program the ATtiny either before soldering using an SOP adapter, or after soldering using an EEPROM clip. The AVR Programmer Adapter can help with this.

If using the Arduino IDE

  • Make sure you have installed MicroCore.
  • Go to Tools -> Board -> MicroCore and select ATtiny13.
  • Go to Tools and choose the following board options:
    • Clock: 9.6 MHz internal osc.
    • BOD: BOD 2.7V
    • Timing: Micros disabled
  • Connect your programmer to your PC and to the ATtiny.
  • Go to Tools -> Programmer and select your ISP programmer (e.g. USBasp).
  • Go to Tools -> Burn Bootloader to burn the fuses.
  • Open the TinyBling sketch and click Upload.

If using the precompiled hex-file

  • Make sure you have installed avrdude.
  • Connect your programmer to your PC and to the ATtiny.
  • Open a terminal.
  • Navigate to the folder with the hex-file.
  • Execute the following command (if necessary replace "usbasp" with the programmer you use):
    avrdude -c usbasp -p t13 -U lfuse:w:0x3a:m -U hfuse:w:0xff:m -U flash:w:tinybling.hex

If using the makefile (Linux/Mac)

  • Make sure you have installed avr-gcc toolchain and avrdude.
  • Connect your programmer to your PC and to the ATtiny.
  • Open the makefile and change the programmer if you are not using usbasp.
  • Open a terminal.
  • Navigate to the folder with the makefile and the sketch.
  • Run "make install" to compile, burn the fuses and upload the firmware.
