Ok, but what is its syscall number? I implemented the syscalls in syscalls.src like this:

Code: Select all

   SYSCALL 040C,   _Serial_ReadOneByte
   SYSCALL 040E,   _Serial_BufferedTransmitOneByte
   SYSCALL 0418,   _Serial_Open
   SYSCALL 0419,   _Serial_Close
   SYSCALL 0414,   _Serial_ClearTransmitBuffer
   SYSCALL 0CC5,   _InputString


But were can I find the numbers (like 040C, 0414)? Until now I just googled it.

EDIT: Seems like I just have to remove 0x

Ok, I was able to implement the syscall correctly. It supports nearly every single mathematical expression (sin, ln, sqrt (as a symbol)) but not spaces and not small chars
Does anybody know how to do that?

You can use your own string input or an implemented one:
1) download mylib
2) include mylib.h
3) declare "struct String * msg;"
4) init string "msg = stringInit("", strlen(test));"
5) get message "stringInput(1, 1, msg, 8, strlen(test), "", 1, INPUT_STRING);"
6) Your data is now "s1->data"

I don't think that you have to clear the transmit buffer more than one time

Strangely, the resulted output on my computer looks always like this:
"Loÿrÿeÿm iÿpsum doÿlÿoÿrÿ siÿtÿ ameÿtÿ"
Does somebody know why?

Looks like some parity problem.
The ÿ always occurs after even-parity characters.

Try to adjust the parity setting on either side:
f.i. here:
mode[ 2 ] = 2;//parity: 0=no; 1=odd; 2=even

SimonLothar: That's exactly what I did yesterday to fix it
Casimo: I already tried that, but I wasn't able to read the information from s1->data...
That works now, but, when compiling, the linker aborts.
First, I got an undefined external symbol error "_stringInput" (which was fixed by changing the name of the specific syscall in syscalls.src), and now he would like to see "_stringInit" defined, but I am not familiar with that syscall and wasn't able to find it in SimonLothars work...
Does somebody know that syscall? Does it even exist?

BTW, Casimo: In your example the information should be stored in msg->data, not in s1->data, or am I wrong?

stringInput and stringInit are functions contained in mylib.c. These are no syscalls.

Yes, I just figured that out, sorry
Well, it works now, here is my final code:

Code: Select all

#include <string.h>
#include "fxlib.h"
#include "mylib.h"

int Serial_BufferedTransmitOneByte(unsigned char);
int Serial_Open(void *sm);
int Serial_Close(int mode);
struct String* msg;

int i;
unsigned int key;
unsigned char demo;
char mode[6];

int AddIn_main(int isAppli, unsigned short OptionNum)
{
    messageBox("Use this program to|tweet via serial","fx-9860GII twitter client");
    Bdisp_AllClr_DDVRAM();
    msg = stringInit("", 50);
    mode[0] = 0;
    mode[1] = 5;
    mode[2] = 2;
    mode[3] = 0;
    mode[4] = 0;
    mode[5] = 0;
    Serial_Open(&mode);
    stringInput(2,3,msg,19,50,"Tweet",1,INPUT_STRING);
    if (strlen(msg->data)>0)
    {
        for(i=0; i<strlen(msg->data); i++)
        {
            Serial_ClearTransmitBuffer();
            demo=msg->data[i];
            Serial_BufferedTransmitOneByte(demo);
            Sleep(100);
        }
        /*This is the tweeting trigger used by the Arduino*/
        Serial_BufferedTransmitOneByte('X');
        Sleep(100);
        Serial_BufferedTransmitOneByte('Y');
        /*----------------------------------------------*/
        Bdisp_AllClr_DDVRAM();
        locate(2,4);
        Print((unsigned char*)"Tweeted sucessfully");
        while(1)
        {
            GetKey(&key);
        }
    }
    return 1;
}

}

Thanks to everybody who helped me starting to code with the SDK!
I'm going to try to add a possibility to enter small characters.
