Virual Terminal In Proteus

Hi everyone
I want to use Virtual Terminal in proteus and send or receive data from my µC(atmega16).
I can send data from µC and receive it with the virtual terminal, but I dont know how to use this terminal to send data to µC..:confused:
how to set this as a sender.

PIC microcontroller and LCD

Hi, I've been working on this issue for days now and I'm not a programmer but I've been trying to make my pic (PIC24HJ12GP201) communicate with my LCD (Matrix Orbital LK204-25). When I connect to output on hyperterm the code works great it shows what it is suppose to show, however I cannot seem to make it work on LCD which is using the serial RS-232 interface. Can anyone please give me an idea as to how to make it work?

Here is the code that I have: [code] #define FCY 25000000 #define BAUDRATE 19200 #define BRGVAL ((FCY/BAUDRATE)/16)-1 void initUART(void) { PORTBbits.RB4 = 1; ///*************************** // Assign U1Rx To Pin RP0 //*************************** RPINR18bits.U1RXR = 0; //*************************** // Assign U1CTS To Pin RP1 //*************************** RPINR18bits.U1CTSR = 1; //*************************** // Configure Output Functions // (See Table 9-2) //*************************** //*************************** // Assign U1Tx To Pin 11 //*************************** RPOR4bits.RP8R = 3; //*************************** // Assign U1RTS To Pin 12 //*************************** RPOR4bits.RP9R = 4; //UART Initialization// PLLFBD=38; // M=40 CLKDIVbits.PLLPOST=0; // N1=2 CLKDIVbits.PLLPRE=0; // N2=2 RCONbits.SWDTEN=0; // Disable Watch Dog Timer while(OSCCONbits.LOCK!=1) {}; // Wait for PLL to lock U1MODEbits.STSEL = 0; // 1-stop bit U1MODEbits.PDSEL = 0; // No Parity, 8-data bits U1MODEbits.ABAUD = 0; // Autobaud Disabled U1MODEbits.BRGH = 0; // Low Speed mode U1BRG = BRGVAL; // BAUD Rate Setting for 19200 U1STAbits.UTXISEL1 = 0; U1MODEbits.UARTEN = 1; // Enable UART U1STAbits.UTXEN = 1; // Enable UART Tx } /////////////////////////////////////////////////////////////////// int main () { unsigned int place1,place2,place3; int STX,ETX,sign,unit_num; int temperature; initADC(); // initialize the ADC initUART(); // initalize the UART LCDinit(); OutStr(">"); The LCDinit(); Is a function from a header. I didn't included it here, but what the LCD requires to perform tasks is to have decimal values sent to it. For instance in order to clear the screen which I've been trying to do, the following must be done (this is excerpt from LCD manual); Clear Screen Syntax Hexadecimal 0xFE 0x58 Decimal 254 88 ASCII 254 ?X? Description This command will immediately clear all of the contents of the display. so what I've done is make the following commands WriteUART1(254); WriteUART1(88); [/code] I do not know why it does not work by sending this, I have the LCD to it's default setting to 19200 baudrate and that's how i set software too. Please, any help with be greatly appreciated

Voice recognition with easyVR - bridge problem

Hi guys !

I'm working on a vocal recognition with the shield easyVR 3.0. I got both, shield and module.

Actually, I added the easyVR library in the arduino program, and upload the bridge example to my board. I guess that my shield is well plugged with my arduino, I saw some tutorials like this :
http://www.theengineeringprojects.com/2013/04/getting-started-with-easyvr-commander.html
So when I uploaded the bridge example in my arduino, this is what I got in the serial monitor :

"---
Bridge not started!"

As I saw in the same tutorial, I tried to connect the shield with the program easyVR commander. So I chose the same COM as my arduino, and tried to connect but, even if I got the bridge example in my arduino, I always got this :

" device has been found,but the 'bridge" software is not responding or it is outdated. You need to manually download the updated "bridge" software to the device (see instructions)."

Could someone help, I don't understand anything even after many research !

If you need some pictures of how I plugged the shield and the arduino, or what I did in the program, just ask :)

Thanks
