#186683 - serialangle data type
Responding to: Per Westermark's previous message
Per Westermark said:
So what data type is serialangle?

(20+20)*10 = 400. So it must be better than an 8-bit data type.


serialangle is signed int.

Earlier i said my code was like this.
 serialangle = (serialangle + 20) * 10;

 

It is actually like this
serialangle = (accdeg + 20) * 10;
 

in which accdeg is a float type which it can vary fromm -20 to + 20

You shouldn't do any "| 0x30". If the intention is to make it into ASCII digits, then you should use '0'.

I used '|0x30' cause I was told to do so and it worked fine. I will try using '0'
