The K&R book on C specifies that you should not rely on the compiler clearing static data, although most do, its good practice to do it yourself.

One suggestion, add a NULL as the last entry in your array of pointers: a friend asked me how to pass a array of pointers into a funtion and print the strings out from the function...i came up with this, but have a feeling there is a more direct way of doing it? thanks Code: Select all #include "pro...

Personally I prefer to declare the typedef in one: Then when using: The prefix udt, tells me that its 'user defined type'.

Need more information, you are assuming that 'we' know what you are talking about... When you say OK Let's say that I wan't to display my IP address and a subnet mask somewhere on that page. How would I do that? Are you asking for help on how to retrieve your IP address and subnet mask from your sys...

Why the 'const' keyword?

You are a type, I'm puzzled what purpose this serves, you aren't declaring an instance of the structure.

I'm not sure what you were intending to do with your script, but the syntax is not valid. the src element of the script tag should refer to a document reference including the path on the server.

You should look up AJAX, then you can do exactly what you want.

Sorry, I don't and I'm not at home right now, I don't have access to the required information, sorry.

Your PIC will be able to accurately assert RTS when data is sent, Windows won't. If you were to look on a scope, with data and RTS you would see a considerable overlap on the windows side.

If you are using RS485, what protocol are you using? Is the RTS line being asserted during data transmission? If you do need to assert RTS then its unlikely if not impossible to do this in Windows due to the timer inaccuracy. You would be better off sourcing and using an RS232 to RS485 adapter that ...

The type uint8_t is 8 bit, the only difference between a standard type and an unsigned type, is that the Most Significant Bit of the type (MSB) in a signed type is used to indicate the sign of the type. If the MSB is set then the value is negative, if its clear then the type is positive. In an unsig...

Maybe I've misunderstood, but I thought what was being asked for was a way to interpret the HTTP data on the server once it had been posted ? If this is the case then the data will not be chunked, it will be in one contiguous data stream that can be interpreted by the code. If you what you are askin...

POST data follows after the HTTP headers, the end of the headers is indicated by \r\n\r\n (A blank line) The posted data then follows, each data item is prefixed with the name of the field the data corresponds to followed by an '=' character, the data may then be URL encoded. Multiple data items are...

Externals extend the scope of global variables defined in a c module. Globals should only be declared in a single C module, then external references to the globals should be placed in the header. Externals and globals should have a 1:1 relationship, if you have an external that does not have a match...

Looking at your type definition: typedef struct { int a; union { char b[13]; struct { float c1, c2, c3; short d; }; }; } UserStruct; UserStruct UStr[2] = { { 2, "TEST"}, // String is recognized as a string. Everything is fine { 4, { 5.0, 6.0, 7.0, 1}} // Second part is recognized as a string too {5,...

The only thing I would add is that the '&' returns the address of the item in memory. When dealing with character arrays, the string functions expect the last character in the array to be a 0 (null terminator), if they don't find this they will continue reading into memory.

The first line is correct, assuming that noisebuffer is a single dimensional array then the correct code should read: strcat will terminate at the next null, so you must take care that noise buffer terminates with a null at some location after element 5.
