Saving Loading Settings on SD Card with Arduino Revisitedevisited Fixed some bugs, improved stability, changed the file structure for mistake proof reading, added Long integer support. For my Aqua. Tank project I needed the ability to change settings of the system and I needed them to stay after power loss. There is an option to use Arduinos built in EEPROM to pemanently store data, but they have readwrite cycle limit and its messy.

TXTSETTINGS. TXTThe structure of the file goes like this parametername. In my example its ex. INT1. 5ex. Float1. Boolean1ex. Long2. The brackets and were added in the revisit, according to Gregor van Egdom, some text editors have different formatting and it was messing with the new line detection,now the code reads only within the brackets, so its more solid and wont get confused by anything. The code was even tested with the following file and worked flawlessly whatever is outside of the brackets is not read by the code ex. Second Life Obj Files. INT1. 5 THIS IS NOT READex. Float1. 1. 23. 45 BLAH BLAHex. Boolean1 This is a commentex. Long2. 12. 34. 56. Diferencias De Celulas Eucariotas Y Procariotas Pdf here. LOLThis sums all my needs storing integers,long integers, floats, and boolean variables to specify if some feature is on or off. The Setup. Using any available Arduino SD Card Shield even a DIY one will be soon,You have 2 general functions that you use read. SDSettings opens the file, and going line by line separating the parameter name and the value into 2 strings, using another function, apply. Setting that gets both strings with a simple if functions converts it to the right type int,float,boolean,long and applies to the right parameter. My computer will not read my SD card. It is a micro SD card, in an adapter, new, cleaned, no crusty residue. The slot came with one of those fake, plastic ones so it.
