Hello...

In my program I have two serial ports, one hardware and the other one software. I'm using fputc, fgetc, fprintf and Streams to use both serial ports. Does anybody know if the code size usi ...

Wouw! Yesterday I was trying to find a relationship between sides of the trieangle, but never take in consideration the Area. Thanks very much!
I will test it today!

Thanks!!!

Hello

I have 3 points with 3 coordinates each one (X,Y,Z). This coordinates are float points number.
Suppose P1, P2, and P3. I need to calculate the ortogonal distance (the shortest distance) bet ...

It's difficult to explain the main reason, as English is not my native language...but one of the most important reasons is that a binary search is faster!

but it's not working...don't know why... if somebody has a code...or and idea...please post it!
Thanks

Hello... how are you

I have a litlle listo of elemtents stored in a external ram....lets say 26000 floatant numbers... (and I really have this number...jajaja). Also I have an index that sort them ...

Hello

I need tomake a function that takes a float or a int32, and descompose it in 4 bytes.
And then another one, that takes 4 bytes and make the 32bits variable.

How can I do this?

I tried ...

Well.... I have a 74LS245.. me be it's a good option to make the converter. Which IC do you use?. My dataflash doesn't have Ready/busy Pin...

Up to now, the software version is working more than the Hardware

Thanks

I didn't know that I have to put the SCK in high or low before setting CS. As the Status Read function is working, the rest fo the code should work okey.
PICC Version is 3.216, the PIC18F87 ...

Hello.. I used some of the codes posted here for driving a 4Mbit dataflash. I can get the Status byte (so the SPI communication is good, and the Dataflash response). But when I tried to write or read ...

Thanks

Is there any usefull way to display the 4 bytes that compose the float into screen... first to check the operation, second to be able to send a float though the serial or spi port.

Thanks ...
