Hi,
I want to recive Midi-Data with a 8051-UART. Sending Midi-Data with the source below is no problem, but reciving doesn't work:
The lowest bit is allways missd.
And unique bits are also missed.

This is the current source:
===========================
; Projekt CT-TG13 2002/2003 :
; 21.01.2003
;
; The MIDI Interface operates at 31.25 k Baud (+1%)
; using an asynchronous serial data byte
; comprising 1 Start bit, 8 Data bits (0 to 7) and 1 Stop bit.
; This makes a total of 10 bits per serial byte with a period of 320 microseconds.
