经过一番捣鼓,字符显示OK了。
关于硬件:进过前面几次的帖子没有详细说明,这里顺便补充一下。
1 VSS 电源地
2 VCC 电源正(+3.3+0.1V)
3 V0 对比度调节输入
4 RS 数据/指令选择
5 R/W 读写控制
6 E 使能端
7~14 DB0~DB7 数据总线
15 CS1 片选 1
16 CS2 片选 2
17 RST 复位输入
18 VEE 负压输入
19 A 背光正极(+3.3+0.1V)
20 K 背光负极
硬件上注意:
PB11: RS
PB10: RW
PB1 : CS2
PB0 : CS1
PB4 : RST
PB5 : EN
其他引脚可以不连接:
vout = -6.23V 悬空即可
V0 偏压输入.可以悬空
LED+ 连接+3v3
RST 也可以悬空,上电自动复位
实际决定对比度的是vcc,第二引脚!经验值4.0~4.2V duty效果较好
方法2:
威廉希尔官方网站
支持建议, PCB背面电阻R3改成3.9K,Vcc= 3.3V 对比度也是OK的,没有验证.
网友有兴趣可以验证一下,顺便回个帖,嘿嘿。
