Any advice on how to NOT take crappy pics of an illuminated screen? Tnx.

// dice - press a button, get two random dice

It’s not that bad..

ported and simmed on the Q..

you know, you didn’t prime that random generator..

fun stuff.. ~q

4

I do not know the seed command for Nesso or even ESP32. Assuming "not analogRead(A0)"

5

how do you spell assume.. :slight_smile:

copied from mazes..

//initialize random..
  randomSeed(analogRead(0));

had to replace that code as it’s and Arduino function..

used the below taken from cppreference.com :slight_smile:

Dice1 = 1 + rand()/((RAND_MAX + 1u)/6);

and I added the seed to setup..

~q

6

R-O-L-A-I-D-S

Could it be the button was pressed less than 500ms after the previous button press (there is a delay(500))?

I got lost in the cppreference...

[edit] I get a "different" roll every start-up.

7

I wouldn’t lose any sleep over it..

it’s not like random got allot to pick from, 1-6..

only reason why i even noticed is the random function is not part of c, so a i get an error porting to sim and have to replace with the rand() function which of course works different..

~q

8

Oh...

Is there a floating analog pin (the user port or qiic port) or clock LSB register on Nesso/ESP32-C6?

9

i did an anologRead(0) on mine, didn’t seem to complain..

figured that was the first analog pin??
