#165110 - howto test input from serial without stop all operations Responding to: ???'s previous message |
Have you looked at the basic tutorials on the 8051 UART yet?
See: http://www.8052.com/forum/read/165109 See also: http://www.8052.com/faqs/120112 and note that there is a whole section of this site's FAQs dedicated to Serial Communications Questions The RI flag shows when SBUF has a character ready to read; so you could just "poll" this - but you have to be sure that you "poll" it frequently enough to not ever miss a character... Intead of "polling" RI, you could use an interrupt instead... See the above references - and there are many, many more about the 8051 UART. |
