16F18875 Timer 2

[medelec35]

interrupt handler is wrong.
Using PIE1 & PIR1 instead of PIE4 & PIR4

Hi Martin,

Thanks for the bug fix, I'll roll it out to the family.

What do you think of these chips? We are looking to use the 16F18877 device on the PIC E-block. It's slightly cheaper and also more capable and highly remappable, though we will need to add support for remappable I2C into Flowcode.

My personal opinion is that these chips are great, and the similarness to 16F877 gives some advanges. Bigger memory, more space to do things that the old ones could not had fitted : like ethernet+can+sd+other peripherials on same project, 16F877 was too small on memory side, the 16F18877, it fits!

Hi Ben,
I have not tested for any other interrupts as just wanted to get Steve up and running.

Specification wise you can't go wrong with them.
I have only had a quick play with one and it works really well.

As cheaper and more memory it seems like a win win situation.

Edit:
Just checked the rest of the interrupts and there is an issue from Timer1 interrupt.

Func test.c: main()
    92:	T1CONbits.T1OSCEN = 0;
	                  ^ (255) not a member of the struct/union ""
	                     ^ (182) illegal conversion between types
int -> volatile union S300
    94:	T1CONbits.TMR1CS1 = 1;
	                  ^ (255) not a member of the struct/union ""
	                     ^ (182) illegal conversion between types
int -> volatile union S300
(908) exit status = 1
(908) exit status = 1

All I did was add the timer1 interrupt, and left on the default options.

Aha thanks again Martin,

I've fixed that problem now and found a few more timer related typos, always helps to do some compilation testing.
