[UPDATE] Comprehensive Arduino Flash Memory via PROGMEM

[Updated for arduino v1.6] This post is a huge set of PROGMEM examples (done as unit tests) which you can freely copy and paste into your work.

The readership level is set at those who are already familiar with the arduino PROGMEM documentation here and the use of the F() macro and __FlashStringHelper*

Its designed as a reference to save you the “lets see how to make this work” time and communicate common pitfalls. Search for the method you need to use, and see it running in working tested code

Arduino Graphing Libraries

Here is a library to write GNUPlot output from the Arduino. Now the Arduino can produce a graph output that is directly renderable across multiple platforms and cloud services. Does not rely on some gone tomorrow software + lets you edit the plot afterward.

RGB Bias Lighting with Arduino (Part 1)

We are setting up an arduino with a WS2811 LED strip to do RGB based bias lighting effects.

Quick Graphs to make PCB Track Width and Silkscreen Ratios easy.

Recently I had to make a series of circuit boards using Eagle Cad.

I spent a lot of time calculating track widths to make sure my circuit board could handle the current I was using.
Then I had to do more calculations for font ratios. so that that all lines were wide enough to work with the silk screening process.

Sick of this; I quickly used matlab to create a few charts so I could look up the answers quickly.
I thought I would share these charts and the matlab scripts, hope they are useful.

Comprehensive Example Code Demonstrating using Arduino Flash Memory via PROGMEM

The post is a huge set of PROGMEM examples (done as unit tests) which you can freely copy and paste into your work.

The readership level is set at those who are already familiar with the arduino PROGMEM documentation here and the use of the F() macro and __FlashStringHelper*. Its designed as a reference on how to accomplish many different common tasks in PROGMEM , from standard string functions, to structures and arrays. The idea is to save you the “lets see how to make this work” time and communicate common pitfalls.
