Page: 6 .Graphic: Minimum Supply Voltage vs. Temperature.
The graph shows the voltage discontinuities at certain temperatures. The slope increases with increasing current. Arduino generates a voltage of 5.01 V.
How I can I know that there are no discontinuities in voltage between +2 º, +100 º C?
I see in the graph where the discontinuities begin to 2 mA, but I do not see where the discontinuities with 40 mA.
Things like that utilize floating point math and floating point math is quite inefficient on an 8-bit mcu.
A simpler approach would be to use fixed point math.
No it is not a simpler approach it is an approach that runs faster.
We are dealing with a compiler here and simple projects. All those posts and you still haven't got the basic hang of this forum have you.
