MOV SBUF,A ; and send out the lsb of DAC A
; DAC C next
; DAC C codes should be taken from 16 bytes (8 samples) further on
; in the sine table - this gives a 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 C msb from the table
ORL A,#01H ; set control bits to DAC C address
A_LSB_TX:
JNB TI,A_LSB_TX ; wait for DAC A 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 C
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
C_MSB_TX:
JNB TI,C_MSB_TX ; wait for transmit to complete
CLR TI ; clear for new transmit
MOV SBUF,A ; and send out the lsb of DAC C
; DAC B next
; DAC B codes should be taken from 16 bytes (8 samples) further on
; in the sine table - this gives an inverted sine 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 B msb from the table
ORL A,#02H ; set control bits to DAC B address
C_LSB_TX:
JNB TI,C_LSB_TX ; wait for DAC C 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 B
; get DAC B LSB
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
B_MSB_TX:
JNB TI,B_MSB_TX ; wait for transmit to complete
CLR TI ; clear for new transmit
MOV SBUF,A ; and send out the lsb of DAC B
; 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
