+ * - Radio data is from nature, so if it's evenly tiled in space, it's random enough, but usually it's not
+ * - A unsafe point is the freq that fetch data is from LCG (from Cpp STL) using time as seed, but should be spread out by later random calculation
+ * - A unsafe point is the init data is still using LCG to generate, but used following methods to spread out:
+ * - - Radio data
+ * - - save a buffer of seeds and generate char by char, this cover all the possible chars combination
+ * - - Rollout with teo seeds and get a final char, this spread out again
+ * - - Hash out the generated password and spread out again if you choose. SHA-512 is proven very spreading out in random space by math
+ * - But still, this isn't meant to become a TRNG generator, don't use at critical/high safety requited/important system, this FOSS has absolutely no warranty

+/*
+    DEAR DEVS THIS IS AN EXAMPLE FILE FOR i2C COMMUNICATION
+    YOU have to derive your class from I2cDev and override the init(), and the update()
+    The update() query the device, and send the corresponding Message to the system with the data.
+    The init() must check the device if it is really that this driver meant to handle, and fully set the device up. If all ok, set the device's model to the corresponting enum value from "i2cdevlist.hpp" and return true. Othervise false, so next driver can check it. (since multiple different devices manufactured with the same addr)
+
+    You can create custom functions, that can be called from any app that identifies the device and casts the I2cDev to your class.
+    This can be checked by query the 'model' variable.
+
+    Steps:
+    - Add this new module name in the i2cdevlist.hpp's enum (to the end)
+    - Create a hpp and cpp. (in the init SET THE MODULE to the prev enum value you created). If the filename is i2cdev_*.cpp it'll be added to cmake automatically.
+    - Add this header to i2cdevmanager.cpp, and add an if statement and the init code to the I2CDevManager::found() function. (see examples)
+    - Compile and test.
+    - Create a PR.
+
+    Notes: try to create a minimal code, to save FW space.

+The purpose of this: when creating an ext app it's address will be changed. But the compiler doesn't know this, so when it optimizes literals it can remove something from one ext app, that is included in the other, to save space.
+But when we want to run this app, it won't find the literal at the fake address, so the best case we'll get just garbage or nothing instead of the string.
+So we must use this Language helper that stores the literals in the fw instead of any ext app, so it'll be always available.
+In the first run we must move those string literal here what are not so unique, like "OK".
