#122691 - totally imprecise not enough/too much Responding to: ???'s previous message |
I posted "So, tie DE and !RE together, after a transmission wait a bit time and then pull it low to receive, after receiving wait a bit time and then pull it high to transmit."
Sudheer //put some nops Stefan wait a little bit (..5 nop's) , then start transmitting. BALONEY BS INCORRECT FOOLIDH!!!! The delay is DIRECTLY related to the baiudrate and i ano "a bit of delat" but a minimum of 1 bit time. Less may lose bytes more may lose bytes if 'the other end' turns fast. Now, Sudheer and Stefan do not come back "I tested it" that will be about the most irrelevant statement you can make. Erik |
