is anybody know interfacing micro controller usig vc++ with PC. > [does] anybody know [how to] interface[ing] [a] micro controller usi[n]g vc++ with PC. ========================================================== Plug RS232 cable from DB9 on microcontroller to DB9 on back of PC. Use windows functions 'createfile, readfile, and writefile' to open the com port and read and write characters to microcontroller. Use the UART on the microcontroller to send and receive characters to the PC. Make sure the baud rate is the same on both. Make sure microcontroller has RS232 interface chip like max232 to convert 0-5v signal from microcontroller to +-12V RS232 level. |
