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.
