Thanks,
yes, but works with another version of Framwork and compiled with hi-tech ... tries but fails to do so with the new framework and c18
a few years ago I started to learn using the famework 1.0 and the example you I comment, thanks!

How I can generate a string for display in the debug? When I run this code hangs the pic... Code: public bool outputString(String text)
{
// Output a string to the LCD display
// Encode the passed string into an array of bytes for transfer
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
Byte[] outputString = encoding.GetBytes(text);
// Declare our output buffer
Byte[] outputBuffer = new Byte[65];
// Byte 0 must be set to 0
outputBuffer[0] = 0;
// Byte 1 must be set to our command
outputBuffer[1] = 0x90;
// Byte 2 is our character count
outputBuffer[2] = Convert.ToByte(text.Length);
// Copy the characters from the string into the output buffer
for (Int64 counter = 0; counter < text.Length; counter++)
outputBuffer[3 + counter] = outputString[counter];
// Perform the write command
bool success;
success = writeRawReportToDevice(outputBuffer);
// We can't tell if the device receieved the data ok, we are
// only indicating that the write was error free.
return success;
}
Code: case 0x90: // *** Send text to PIC ***
sprintf(debugString, "Text to PIC");
debugOut(debugString);
for (characterNumber = 0; characterNumber < ReceivedDataBuffer[1]; characterNumber++) {
stringtext = ReceivedDataBuffer[2 + characterNumber];
}
sprintf(debugString, stringtext);
debugOut(debugString);
break;

modify the code and now it works! I do not know if is the right way ... Code: case 0x90: // *** Send text to PIC ***
sprintf(debugString, "Text to PIC");
debugOut(debugString);
for (characterNumber = 0; characterNumber < ReceivedDataBuffer[1]; characterNumber++) {
string[characterNumber] = ReceivedDataBuffer[2 + characterNumber];
}
string[characterNumber] = '\0';
sprintf(debugString, "%s", string);
debugOut(debugString);
break;

Now if it all works, send text to the PC and the LCD... Again is the right way? Code: case 0x90: // *** Send text to PIC ***
sprintf(debugString, "Text to PIC");
debugOut(debugString);
for (characterNumber = 0; characterNumber < ReceivedDataBuffer[1]; characterNumber++) {
string[characterNumber] = ReceivedDataBuffer[2 + characterNumber];
}
string[characterNumber] = '\0';
sprintf(LCDString, "%s", string);
// Clear display
while (BusyXLCD()); // Wait if LCD busy
WriteCmdXLCD(0x01); // Clear display
putsXLCD(LCDString);
sprintf(debugString, "%s", string);
debugOut(debugString);
break;

Looks ok to me. The code copied the number of characters indicated by receiveBuffer[1] into an array of char and then terminates the string with '\0' (to make it into a normal C string) before passing it to the LCD.
