Hi all Matrixmultimedia developpers,

My suggestion is to develop a new component for easy use USB implemented in PIC 18F4550 for example.
USB Component could be a easy way to develop application to read and write value between PC and PIC (in bulk mode) with real USB and not through the RS232/USB ...

Hi all,

What is the flowcode HID USB example use for ? If i download it in the PIC ,how can i use it ? which connection i need ?

Thank Steve,

Hello,

I want to communicate with PIC18F4550 with it's USB interface.
Is there any specific Component to have direct access of USB (like RS232 component ) in Flowcode ?
Someone has a exemple to program USB of PIC18F4550 ?

Thanks.

Hi all,

I want to simulate Push Button with a PIC and control it by RS232.(Letter 'A' shall put the Bit 2 of port B to low during 200ms)
In attached below you can see an extract of by file.
My problem is that the delay of 200ms is not respected.
If i send quickly Letter 'A' the delay is shorter ...

Thanks a lot for you reply Sean,

I will try to test my circuit directly with the PIC.

Hi,

My project consist in replace 8 push buttons of my card by a PIC to simulate those push buttons and controlled it by RS232.
I use PORT B of my PIC and I just want to know if i need to use a "intermediate" circuit (like ULN2803 ie) to interface to my card or can i connect my PIC directly. (my ...

Hello,
Yes a use Flowcode V3 Professionnal,
This code is in a file bintodec.c ,I added
char BIN_TO_DEC(char IN); to the definition and
#include "bintodec.c" in the suppementary code.

I went to use this code like a function in My main program like:
FCV_B = bintodec(FCV_data); (data = string and B ...

I am beginner in language C

I create a function to translate string (ex:"10110") in a integer ,but compilation is on error in the first line:

bintodec.c(1): error: missing semicolon
bintodec.c(1): error: failure

here is by function :

int Bintodec (char* IN)
{
char I;
char X;
int RESULT;
char ...

Yes Benj,

Thank a lot,It's better using hardware.......

I have a other question :

Is it possible to have the function pow(x,y) in flowcode ??
If i use it I have a message error ?
How can i use X^Y ??

Thank for you replay........

Hello,

How can I send you my file ?

Thank you for you reply Benj,

I try to do the same program with 20MHz crystal,but it doesn't work .
I don't know why ;With 20MHz each instruction take 0.2us Right ?
For my capture, the delay between two bit is 80us ,So why PIC don't have enough time to execute a read of PORTB ,tranfert it in a text ...

Hello,
I'm a new user of Flowcode.
PIC use : 16F877A. XTAL Frequency : 4MHz prescalaire to 16
I need to capture data bus on RB4 composed by word of 32 bits of 12.5Khz .Each Word are tranmit every 300ms.
But as i don't have any synchronisation or bit start and bit stop ,I use a second bus connected ...
