In the 51 microcontroller, can choose to send the ninth as the parity bit, it is need to judge the check digit in the receiving interrupt? Received 0 x90 sbuf data, for example, requires cyclic shift to judge the number of 1, plus 1 or 0 RB? Send time is also need to calculate, then will be 1 or 0 to TB, and then sbuf?

CodePudding user response:

51 remember not can design the register set up 10 or 11? Oh, you don't need to manually calculate SBUF only eight, you didn't place calculated
