APPLICATION INFORMATION
; DAC D next
; DAC D codes should be taken from 16 bytes (8 samples) further on in the sine table
; – this gives an inverted cosine function
MOV
A,R7
; pointer in R7
ADD
A,#0FH
; add 15 – already done one INC
ANL
A,#03FH
; wrap back round to 0 if > 64
MOV
R7,A
; pointer back in R7
MOVC
A,@A+DPTR
; get DAC D msb from the table
ORL
A,#03H
; set control bits to DAC D address
B_LSB_TX:
JNB
TI,B_LSB_TX
; wait for DAC B lsb transmit to complete
SETB
T1
; toggle FS
CLR
T1
CLR
TI
; clear for new transmit
MOV
SBUF,A
; and send out the msb of DAC D
INC
R7
; increment the pointer in R7
MOV
A,R7
; to get the next byte from the table
MOVC
A,@A+DPTR
; which is the lsb of this sample, now in ACC
D_MSB_TX:
JNB
TI,D_MSB_TX
; wait for transmit to complete
CLR
TI
; clear for new transmit
MOV
SBUF,A
; and send out the lsb of DAC D
; increment the rolling pointer to point to the next sample
; ready for the next interrupt
MOV
A,rolling_ptr
ADD
A,#02H
; add 2 to the rolling pointer
ANL
A,#03FH
; wrap back round to 0 if > 64
MOV
rolling_ptr,A
; store in memory again
D_LSB_TX:
JNB TI,D_LSB_TX
; wait for DAC D lsb transmit to complete
CLR
TI
; clear for next transmit
SETB
T1
; FS high
SETB
T0
; CS high
