Hello

@ Ttelmah:
About this Motorola 78LC05: I searched Google, some semiconductor catalogues, etc. but I can't find the datasheet or some place to buy a device.
Is this an older part number (R ...

Hello

to the value of reference I should use

That depends on your analog input volatage range.

how to configure the PIC to use this reference

Should be in the datasheet or the CCSC manual ...

Hello

GP0 and GP1 are the comparator inputs. I think you have to first switch off the comparator module to use this pins as I/O.

Happens to me with a PIC12F675...

Yeah, my calculation is for US, I'm sorry, I should' ve mention that...
I'm studying etech and we use c for any propagation speed. We get it from the context, if it means sound, light or whatever.

Hello

...at least 100 measurements per second...

Could be a bit difficult:

c = 340m/s
round-trip distance: s = 2*3m = 6m

round-trip time: s/v = ~17ms

=> maximum measurement frequ: ~ ...

Hello

That statement about register values at reset is at page 38:

Some registers are not reset in any way; they are
unknown on POR and unchanged in any other reset.
Most other registers are ...

Hello

I have some problems with signed integer multiplication:
I multiply two signed ints together, to get a signed long, but the result looks like it's treatend unsigned internally:

#include ...

Hi

I agree, the setup_tris_b(0) is wrong if you want to use the pin as an input. But that isn't your problem, because unless you'r using fast_io (which you don't) the compiler handles the tris bits ...

Hello

if(solbas == 0)

solbas is defined as PIN_B0 and PIN-B0 is defined as a constant value in the header file (look at it). S you'r comparing a const to another one, with the never changing re ...

Hello

It's not exactly the same as orginally asked, but something similar:

What should I do, if the two bytes of a long aren't in consecutive oder. For example I want to do this:

long any_var ...

Hi

I forgot to mention that I'm using a 16F part... I think thats still 8bit no ?
Yes, thats true, TMR0 (or the RTCC) is 8Bits.

Look at your list file to see what setup_timer_0(RTCC_INTERNAL) w ...

Hello

What do you mean with "it doesn't work"? Does it compile? What exactly doesn't work, what results do you get?

Hi

unsigned char is from 0 to 255
signed char is from -128 to +127

Hi

I think you selected a PIC in MPLAB that is to new for your PS+ with version 2.1. With "device" it means the PIC device (it should be shown in the MPLAB status bar).
To program your PIC, you ha ...

Hi

How do you want to reset your PIC? By hardware signal or by a received RS232 command?
Can you specify your problem a little bit more?
