void GpioInit(void) { // Set to inputs FIO0DIR = \ FIO1DIR = \ FIO2DIR = \ FIO3DIR = \ FIO4DIR = 0;
// clear mask registers FIO0MASK =\ FIO1MASK =\ FIO2MASK =\ FIO3MASK =\ FIO4MASK = 0;
// Reset all GPIO pins to default primary function PINSEL0 =\ PINSEL1 =\ PINSEL2 =\ PINSEL3 =\ PINSEL4 =\ PINSEL7 =\ PINSEL8 =\ PINSEL9 =\ PINSEL10 = 0; }
How can I change PINSEL1 with this code?
Well, it isn't too common that a C expression might be long.
But the OP should by now have figured out that the C compiler does not need any \ at the end of the lines to concatenate individual text lines into a single line. Not even when someone needs to print a very long text string is it needed to use any \ to split the text string over multiple lines.
I feel increasingly superfluous to this discussion. You are free to discuss it amongst yourselves.
We are.
It is very pleasing to hear you acknowledge the fact. You two are sure to both learn something new from your discussion.
And have you learned anything - like how to deal with compiler messages, where the backspace is & isn't used for line continuation, and whether those huge long expressions are necessary or desirable...?
Actually, I rather doubt that backspace is used anywhere for line continuation!!
(yawn)
you two carry on without me.
K Panjaab,
You should first remove all spaces behind \.
void GpioInit(void) { // Set to inputs FIO0DIR = \ // ^ A space at above position.
Then
PINSEL0 =\ PINSEL1 =55;
You set both PINSEL0 and PINSEL1 to 55. (0x37)
As Per Westermark already told you. But the OP should by now have figured out that the C compiler does not need any \ at the end of the lines to concatenate individual text lines into a single line. Not even when someone needs to print a very long text string is it needed to use any \ to split the text string over multiple lines.
This also works.
void GpioInit(void) { // Set to inputs FIO0DIR = FIO1DIR = FIO2DIR = FIO3DIR = FIO4DIR = 0; // clear mask registers FIO0MASK = FIO1MASK = FIO2MASK = FIO3MASK = FIO4MASK = 0; // Reset all GPIO pins to default primary function PINSEL0 = PINSEL1 = 55; PINSEL2 = PINSEL3 = PINSEL4 = PINSEL7 = PINSEL8 = PINSEL9 = PINSEL10 = 0; }
Thanku John Linq. With that post, the lazy OP got what he was searching for - a direct working answer.
And the guy ( or girl - the gender is stochastic here) has got a serious attitudinal problem.
by the way, k panjaab, which part of India do you hail from?
That is very true; but not in the way you thought.
The responses here are very good material for my research.
Some contributors discuss the unmentioned portion of the OP's question to better understand the question, and to provide better help to the OP. I think this fine.
However, doing a community behavior research might be OK here. But fooling people is very bad.

If you ever come to my town, stop me and ask "can you tell me the way to the station?", I'll be sure to just reply "yes" and carry on walking.
But when you get to a rental agency and ask "which car would you recommend", you would probably prefer if they check on your needs before recommending a car. If you are alone and want fun driving then a 2-seater or 2+2 car might be recommended. If you are going to move to a new apartment, then you might get more use of a van.
In your case - the direction to the station would probably differ for a pedestrian or if they have a car. And it would probably make a difference if they go there to pick some up with the car, or if they need to park the car before taking the train - the long-term parking lot might not be directly at the entrance.
In your case - the direction to the station would probably differ for a pedestrian or if they have a car.
In a role reversal, if I were to ask someone the way to the station and they then responded with "before I can answer that, you must explain in minute detail what the reason for your request is and what you intend to achieve when you get there and you must confirm that you have read and understood the ubiquitous webpage on how to ask a smart question", I'd just drive on and hope that the next person I ask is a little more sensible.
But a large number of people who on this site come and ask questions, doesn't just want to know the driving directions to the station. They also want to know the driving instructions for the car. You find them sitting on top of the roof of the car like Mr Bean, and they require information how to get the car running (does it need fuel too???) what button to press to get the car to correctly auto-navigate etc.
