#88859 - REN !! Responding to: ???'s previous message |

In all the code and examples I have there is no mention about REN. How do I put it to 1? REN is a bit in an 8051 SFR (Special Function Register). REN = Receiver ENable: it enables the Receiver part of the UART. Obviously, if you don't enable the receiver, you will receive nothing! You set it to 1 the same way you set any other bit in any other SFR to 1! Sounds like you need to review the UART operation in the "bible:" Chapter 1 - 80C51 Family Architecture: http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set: http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf |
