#161837 - package is MAX232 DIP package Responding to: ???'s previous message |
I am using AT89C51 DIP and Maxim Max232CPE DIP package... Used 1uF capacitors only.
In the PC i set to COM1 port to 9600 baud rate,8 data bits, no parity, no flow control, 1 stop bit. still it is not receiving the byte from micro to PC. we have VB program which sends and receive data from micro 8051. even the VB program is set for 9600 baud rate. Let me know anything is need attention on Carrier Detect etc operation to receive data from 8051 to PC. please check my earlier C code .. |
