I'm starting a project using the Realtek RTL8305SC ethernet switch. Does anybody have a good idea of how to use it, some code for it, or even a flow diagram of how it should be used in conjunction wi ...

What "basic stuff" are you referring to would you have to write yourself?

Yes, but what else did you like (other than #USE RS232) that C18 did NOT have that CCS did have (or vice versa?)

I will be using the "full" version, not the student edition.

What kind of macro's does CCS provide that C18 does not? Would it be terribly difficult to do them myself? Also, I don't bel ...

I have used CCS's compiler for years (5 years to be exact) and have been very happy with it. However, for a "side job" I am required to use C18. What are some of the things I should know, ...

Does that mean that the CCS compiler automatically disables interrupts during those functions, or do I need to do that separately?

Also, I'm not doing any 'move' operations, I don't think.

Ttelmah, I'm not sure I understand your first sentence. Do you mean that if I am calling a function in my ISR (let's say function MovePiston() ), then each time my code OUTSIDE of the ISR calls MoveP ...

I'm currently working with the PIC18F4685, and I have an interrupt that executes every 0.5 milliseconds (i.e. 2000 times per second). What I'm finding in my code is that sometimes instead of happenin ...

Yes, but do I have to do that delay manually? I would have thought thats done automatically in the read_adc() function (as long as its returning a paremeter).

Also, what should the TAD value be set ...

When I set up my ADC, I just do this:

setup_adc_ports( AN0_TO_AN4 | VSS_VREF );
setup_adc(ADC_CLOCK_DIV_32);
set_adc_channel(0);

My first question is: For the " ...

Hi everyone,

I am having an odd issue with CAN. The CAN interrupts work and my code works much of the time. However, when I send a lot of messages to CAN, occasionally I find that the CAN receive ...

I see in the manual it lists the _fixed(n) type qualifier. I'm not really sure how to use it. Do I do something like

int_fixed(2) nTest;

for a 2 place decimal value? Then when I use ...

In my code, the filter is letting everything through, regardless of the ID that it is getting. My mask is 0x100FF000 and my filter is 0x10011000. If my ID is 0x10044000, the message is getting throu ...

I am trying to enable CAN filters in my code, but using the "can_enable_filter()" function gives me a "Undefined identifier" error in my compiler. What gives?

Also, I tried wit ...

I found the problem. my canSetBaud function needs to have one more line in, and then the final function will look like this:

void canSetBaud(void)
{
can_set_mode(CAN_OP_CONFIG& ...
