,240,128 240×128液晶显示
问
请问高手,有没有用过Youth的240×128液晶的程序,怎么不能显示。请问直接接口是怎样接呀,我用的是连线图:
*DB0---P0.0* *DB4---P0.4* *C/D-------------P2.0* */RD---------P3.7*
; *DB1---P0.1* *DB5---P0.5* *CE--------------P2.1*
; *DB2---P0.2* *DB6---P0.6* */RW-------------P3.6
; *DB3---P0.3* *DB7---P0.7* */RST------------VDD

答 1: 建议用异步接口同步接口用时候会有问题
建议用异步接口
等数据线、读写控制信号稳定后在使能片选端
~~~~ 答 2: 恩,用异步接口... 答 3: 谢谢啦! 答 4: 如果程序没问题的话修改一下端口定义就可以了// T6963C 端口定义
#define LCMDW XBYTE[0xfeff] // 数据口
#define LCMCW XBYTE[0xffff] // 命令口
