Story

Cute P-chan running with ATtiny13 and 3 reversed mount LEDs. Use ISP pads to create awesome LED sequencing and push button to change modes.

Some of you may remember Ranma 1/2 classic anime from the late 80s it was super popular in Latin America during the 90s and P-chan was the cutest!

The design was done using Inkscape svg2schenzhen extension

Inkscape design

I generated the ground plane with Inkscape extension it was part of the mod file imported as a symbol to KiCAD, but did not notice the opening was missing when I added a connection to Power (see second image below).

1 / 2 • Inkscape layout

So the design had an awful short but it was a quick rework (thanks Abraham).

P-chan test

Code is still WIP but see the Arduino sketch for reference. We'll update the design and post the project to github or similar.

We use the hex file generated from Arduino IDE to program the ATTINY with ATMEL Studio and ICE programmer.

/********************************************************* 
 This sketch demonstrates the use of a watchdog timer.
 The watchdog timer causes a processor reset to occur if
 it is allowed to time out. When the sketch is running
 inside the second while loop, the watch dog timer is
 consistently reset to prevent a timeout. When PB0 is 
 pulled high, it breaks out of the while loop and causes 
 the watch dog timer to reset the processor.
