SOS！ 哪位有SSD1815（SOLOMON公司）液晶IC的驱动程序

[hzwpf]

使用Serial mode !
具体口线：CS RST CLK DA A0
如何使用，多谢指教

[incaution]

;关键在于写命令字和写参数，其他初始化的设置按pdf文件说明

TRANS_COMM: ;写命令字，入参data_port

clr cs
clr ao
mov r7,#8
loop1:
clr clk
clr c
mov a,data_port
rlc a
mov da,c
nop
mov data_port,a
setb clk
djnz r7,loop1
nop
nop
nop
setb cs
ret

;==================================================
TRANS_DATA: ;写数据，入参data_port

clr cs
setb ao
mov r7,#8
loop2:
clr clk
clr c
mov a,data_port
rlc a
mov da,c
nop
mov data_port,a
setb clk
djnz r7,loop2
nop

setb cs
