Any body can help me that how can i give data to MCU from PC using the hyperterminal or any other terminal through serial port. my prog properly work on KEIL but when i burn the hex file it can work as it work on keil serial window
have you triple checked the connections to your MAX232(equivalent)? Erik
I m using the nrf24E1 board which has built in MCU with transciver and Max chip for serial port as well. i utilized the 9 pins for serial port and i already transmitted data on PC but cant transmit from PC to board
Are you sure the handshaking signals are not active and the Terminal software doesn't use handshaking.
Do you initialize your serial port properly? If you debug from µVision this has been done by the MON51.
