Final answer:
To receive data serially using 8051 microcontroller with a baud rate of 19200 and save the received data at RAM location 40H, you can follow these steps: Set the baud rate, configure serial communication settings, write the interrupt service routine, and enable interrupts. Use HyperTerminal and the Memory window to see the received data.
Step-by-step explanation:
Program to receive data serially using 8051
To receive data serially using 8051 microcontroller with a baud rate of 19200 and save the received data at RAM location 40H, you can follow these steps:
- Set the baud rate using Timer 1. With XTAL = 11.0592MHz and a baud rate of 19200, the TH1 and TL1 values can be calculated.
- Configure serial communication settings by setting SM0 and SM1 in the SCON register to 1, TCLK and RCLK to 1, and REN to 1.
- Write the interrupt service routine to handle the received data. In the ISR, check the RI flag to see if data is received and save it at RAM location 40H.
- Enable interrupts and wait for the data to be received.
You can use the HyperTerminal to send data to the 8051 microcontroller and observe the received data by checking the memory location 40H in the Memory window. Make sure to select the correct COM port and set the baud rate to 19200 in HyperTerminal.
Remember to create and configure the necessary hardware connections and make sure your microcontroller board is setup properly.
