#84176 - Problem displaying posts? Responding to: ???'s previous message |
I mentioned the oversampling as a means of detecting the edge of the startbit in my first posting to this thread, mentioning there also the possibility to use timer2 interrupt for the same purpose; and was discussing both ideas further in the subsequent posts. Maybe the postings don't display to you and Andy completely? I use the "flat" mode and I see all my text, but as I understood you are using the traditional "threaded" mode - maybe there is some problem with it? If you set mov t2con,#6 mov th2,#0FFh mov tl2,#0FFh setb et2 setb ea the first 1->0 transition on P1.0 pin will increment the timer value, causing overflow to 0000h hence firing the interrupt. To "reenable" the edge detection, th2:tl2 has to be reset to 0FFFFh. Jan Waclawek |
