Communication whit Robonova through port serial

2007-06-18T18:40:48+01:00

Hi Guys:
I tried swapping TX and Rx connections to the MR-C3024, but it didn't work.
I look that RX and TX to the MR-C3024 is in high voltage 5V and I have a doubt: The pin RX must be in 5V but the pin TX mustn't in 5V?. I suppose that the RX must be in 5V because always ought to be receiving data.
But I look that both is in high. I don't know if I'm wrong.

I will try agian swapping RX and Tx and debug the connection in parts.

Thanks, we will follow in contact.

You need to debug the connection in parts.

It is along time since I saw a serial program which writes direct to UART registers. This makes me suspicious of the PC part. I suggest to add a read from the com port and printf within the PC program. Then test in loop- back first on the RS232 TX and RX, then the TTL level conections normally connected to the C3024. If both of these work, then look to the Robobasic code, or swap the connections as Pev suggests.

If the RS232 loopback works and the TTL does not, then suspect the Max232 circuit. If you want to connect by wire from PC to Robonova, you can do this simply with the standard serial cable. Make sure Robobasic is not runing on PC, so serial port is free. Any character between 0 and 0x7f which is sent to the serial cable connected to the RoboNova will automatically appear in the first defined variable (RxIn in your program). 0xFF is also passed, but do not use values between 0x80 and 0xFE, since these are serial commands.

Hi

the code :

Retry:
ERX, 9600, RxIn, Retry

Looks right to me - it says recieve a byte from ERX at 9600 baud into variable RxIn and goto retry if it fails

When I first played with the ERX/ETX ports I had a lot of issues working out which port was which, they do not seem to be logically labelled and I ended up reversing the TX/RX connections to what seemed to be the wrong way but it worked.

Have you tried swapping TX and RX connections to the MR-C3024 around?

Hi Gort .
Another quiestion:

I need put this line for that controller receive throug port serial
RxIn=BYTEIN(port number), or RxIn=IN(port number)?

But how I know that port number is the port ERX?

Hi Gort.
Thanks for check my code. Look I need that Robonova receive for the serial port the byte that i send through to the Pc with the code in C.
In the code RoboBasic I put this line:

Retry:
ERX, 9600, RxIn, Retry

I supposed that whit this line, RoboBasic would receive the byte, but I don't know if this is right.

Other problem it's that I connected the serial cable to the pin ERX throug max232 for regular the voltage, but this not work. I don`t know if the connection whit the pin ERX is right because I don't know like robonova interpret that serial port it's.

I see that exist the port serial whit which i program the robot and the port serial that the controller has, using the pins marked like ERX y TX. I don´t know how recognize that port is?

Sorry, my english isn't very good!.

after further review, it looks like the C code is correct. I am still not sure How Robobasic is getting the value of the byte passed to it by the serial port?

Is the robonova getting the value of RxIn in the Robobasic statement:

Retry:
ERX 9600, RxIn, Retry

Can Some translate the Spanish comments?

2007-06-13T16:44:49+01:00

If some one could translate the Spanish comments in the C code it could make it easier to help? In the C code the switch statement dose not look right. When is a value moved into valor and I am not sure if the syntax is correct? I need to look at it more and walk through what it is doing. C is not one of my strong languages. Also Could it be in the way the serial connection is hocked up?

Hi. I hope that you can help me.
I realize a program in C that send a byte through of the serial port to the Robonova and this receive too trouhg serial port but this not work. I don't know that I'm realize wrong.

I use a Max232 to convert the voltage, but in the moment in that I connect the signal of gnd and erx, the headlight of the robonova turn on but this not realize nothing when i sed it a data.
I connect the signal gnd in the pin corresponding of the three that have this. I don´t connected the middle pin because I supply the voltage to the max apart, in the pin of signal I connec the cable rx.

Here the program in C and the program in Robobasic.

Code in Turbo C

Code:: #include #include #include #define COM1 0x3F8 void inicializar_puerto (); void main() { int valor,i; unsigned char tecla; clrscr(); inicializar_puerto(); gotoxy(20,5); printf("EJECUCION DE RUTINAS DEL ROBONOVA"); gotoxy(6,10); printf("1.-Dar un paso con pie izquierdo."); gotoxy(6,12); printf("2.-Dar un paso con pie derecho."); gotoxy(6,14); printf("3.-Levantar mano derecha."); gotoxy(6,16); printf("4.-Levantar mano izquierda."); gotoxy(9,18); printf("Selecciona una Rutina: "); scanf("%d",&valor); switch(valor) { case 1: outportb(COM1,valor); gotoxy(6,21); printf("ROBONOVA-1 Da un paso con pie izquierdo"); break; case 2: outportb(COM1,valor); gotoxy(6,21); printf("ROBONOVA-1 Da un paso con pie derecho"); break; case 3: outportb(COM1,valor); gotoxy(6,21); printf("ROBONOVA-1 Levanta mano derecha"); break; case 4: outportb(COM1,valor); gotoxy(6,21); printf("ROBONOVA-1 Levanta mano izquierda"); break; default: for (i=7; i<8; i++) { textattr(i + ((i+1) <<4)); gotoxy(18,22);cprintf("Debes introducir un n£mero del 1 al 4!"); } break; } getche(); } void inicializar_puerto() { outportb(COM1+1,0); outportb(COM1+3,0x80); outportb(COM1+0,0x0C); outportb(COM1+1,0x00); outportb(COM1+3,0x03); outportb(COM1+2,0xC7); outportb(COM1+4,0x0B); }
