#define NumberOf(arg) ((unsigned int) (sizeof (arg) / sizeof (arg [0]))) // calculates the number of layers (in this case 4)

*calculates the number of "elements in an array" not "layers"

Destructor not Destractor

In the readme.md, I have cutstom instead of custom in a title

[GiorgosXou]

In the readme.md, Summary > Output column, change float to DFLOAT typo

Nothing too important, just a visualization thing, make those horizontal

This softmax part-implementation for use with any ACTIVATION__PER_LAYER, (even thought I trust myself, not gonna lie) seems slightly suspicious:

NeuralNetworks/src/NeuralNetwork.h

Line 2041 in da5b5af

void NeuralNetwork::Layer::Softmax() {for (int i = 0; i < _numberOfOutputs; i++){outputs[i] /= me->sumOfSoftmax;}}

And by suspicious, I mean: i don't remember 😭 + division lol

[GiorgosXou]

Reminder: Remove space in middle after = :

NeuralNetworks/src/NeuralNetwork.h

Line 1509 in da5b5af

layers[i].weights[j][k] = *((DFLOAT*)(&tmp)); // toFloat() which is atof() is not accurate (at least on Arduino UNO)

I forgot to remove it, when I was copying a previous example, lol:

NeuralNetworks/examples/Media/Save_NN_to_internal_EEPROM/Save_NN_to_internal_EEPROM.ino

Lines 14 to 24 in da5b5af

	// Default Test/Input data
	const float inputs[8][3] = {
	{0, 0, 0}, // = 0
	{0, 0, 1}, // = 1
	{0, 1, 0}, // = 1
	{0, 1, 1}, // = 0
	{1, 0, 0}, // = 1
	{1, 0, 1}, // = 0
	{1, 1, 0}, // = 0
	{1, 1, 1} // = 1
	};

On Arduino Uno usually you need to specify CS pin to whatever you have it, usually begin(4), it's nice to have as a comment

Line 41 in da5b5af

if (!SD.begin()) {

AAAAAAAAAAAAAAA, sorry but i have an error that fried my head and I can't even write propperly lol
