PIC16F345 and DT_INTS-14

[dran11]

Sorry, it is PIC16F15345. Attached is modified DT_INTS-14 but does not work.

to start with you have not fully defined how the main OSC is setup i would add
OSCCON1 = $62;
secondly you have not set a clock source for timer1, as it is it expects a clock signal on the t1clk pps pin you probably don't want that
T1CLK = 1; ClockSource FOSC/4; 534mS
is more like it
thirdly the chip has auto context save for interrupts so wsave etc are not needed or even useful

i don't have a 16f15345 chip on hand and my simulator has no model for them either so the code is untested

but try this

found a 16f15313 in my junk box which is from the same family tree

changing pins to suit all works as expected
