RECEIVING INFORMATION on PC FROM MICROCONTROLLER BY RS232

[tusemo]

Does anybody have (or know) visual c sharp code to receive data from rs232 ?

It's not that difficult to write. You have to open the MSComm port and set the parity, baudrate, stop bits. and then transmit / receive data. If you want I can try. I have done that in VB.net

Try this app to receive serial data.

is it possible to sen information to pc what ever I want (no time restristion) ?, Should I use 9-pin serial port's some pins more than Rxd and Txd

You only has to use three pins Rx, Tx, and GND. You have to connect your MCU's Rx and Tx pins to MAX232 and then connect the output of MAX232 to PC.

If your PC does not have a serial port (most computers nowadays don't), you have to either use USB or a USB-to-RS232 converter and then use RS232.

Than you all.
