 		 #117978 - My settings from the 80's
Responding to: ???'s previous message
My first MIDI project in the 80's was a converting a set of organ bass pedals to MIDI for a client. Here are my settings for a vanilla 8051 with a 12MHz crystal):

Save This Code
           MOV TMOD,#$20   ;DISABLE GATE
                           ;TIMER MODE
                           ;TIMER 1, MODE 2
           MOV TL1,#$FF    ;RELOAD VALUE=255
           MOV TH1,#$FF
           MOV TCON,#$50   ;BOTH TIMERS RUNNING
           MOV SCON,#$70   ;MODE 1, 8 BIT UART


It was tx-only. I can try and find some other project code, but it might take a while.
