ATtiny13 TinySat

# TinySat - Solar Powered Blinken Lights TinySat collects the energy from up to two solar panels (max 6V) and stores it in a 1 Farad super capacitor. The ATtiny13A uses this stored energy to make two LEDs blink - even when the sun is not shining. - Firmware (Github): https://github.com/wagiminator/ATtiny13-TinySat  # Hardware  # Compiling and Uploading the Firmware Since there is no ICSP header on the board, you have to program the ATtiny before putting it into the IC socket. The [AVR Programmer Adapter](https://github.com/wagiminator/AVR-Programmer/tree/master/AVR_Programmer_Adapter) can help with this. ## If using the Arduino IDE - Make sure you have installed [MicroCore](https://github.com/MCUdude/MicroCore). - Go to **Tools -> Board -> MicroCore** and select **ATtiny13**. - Go to **Tools** and choose the following board options: - **Clock:** 128 kHz internal osc. - **BOD:** disabled - **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](https://aliexpress.com/wholesale?SearchText=usbasp)). - Go to **Tools -> Burn Bootloader** to burn the fuses. - Open the TinySat sketch and click **Upload**. ## If using the precompiled hex-file - Make sure you have installed [avrdude](https://learn.adafruit.com/usbtinyisp/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:0x3b:m -U hfuse:w:0xff:m -U flash:w:tinysat.hex ``` ## If using the makefile (Linux/Mac) - Make sure you have installed [avr-gcc toolchain and avrdude](http://maxembedded.com/2015/06/setting-up-avr-gcc-toolchain-on-linux-and-mac-os-x/). - 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. # License  This work is licensed under Creative Commons Attribution-ShareAlike 3.0 Unported License.
