Hello you I want to build some function for RS485 realize. the algorithm of this function is next :
1. Set bit of I/O register to 1 for enable of transmit RS485 driver 2. write something to port 3. tcdrain() for transmission complete 4. Set bit of I/O register to 0 for disable of transmit RS485 driver But problem is in incorrect tcdrain() working. Function does not provide of waiting of data transmission process complete Can you give some comments, or some solution of this problem Thank you _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
