not sure , for the 16f1788 the microchip ipe with pk4 warns , 5.00 v recommended (not sure where the ldo comes into play)



as i don't , i have never seen or heard of a pic having an adverse...

your not trying to run chip at less than 5v ? decouple caps etc [i'm using none]
reset is pulled high ?
enc and sw pins are pulled high with suitable r

i cannot get mine to fail no matter hard i...

would seem that way , although his dt_ints may be altered.
only changes i made

latc.6 = 1 ' reversed polarity tty
serout2 PORTC.6,84,[13,10,"I'm Alive",13,10,10]

not to mention that mine ,same code same chip does not reboot

the reason i ask is that if your programmer is still connected and the programmer is used to power your proto board .
some leave the icspclk pin on the programmer as a high output , if your RE...

one thing you can eliminate is a code problem [assuming code as posted] mine is has run for 24 hours+ without resetting

describe your setup including whether you leave the programmer attached...

mine has been running for 4 hours now , nill resets

i breadboarded a 1788 and using the code as posted in reply 8 with one slight change in that serout2 is set to T9600 it
1. fails to count properly as predicted
2. shows no signs of resets...

if you look at the expected b5,b6 pin values at each interrupt
for neg edge trigger only

ints occur on orange lines
9010
under ideal conditions you get for say cw rotation...

all you have to do is post the code for your attempt and i will have a look


hints

serout2 PORTC.6,16468,[13,10,"RE_val ",dec5 RotEnc1_val] once in an isr is bad twice is just asking for...

oneway to count detents divide the absolute raw cnt value by the number of edges/detent ,then restore the sign
eg
sb= cnt.15
detents = abs(cnt)<<2; four edges
if sb then detents= ~detents+1

for mechanical encoder with button i use something like this
