客户在一个项目中显示屏部分共需要35个GPIO,其中需要并行操作的GPIO有25个,主要实现输出控制信号功能,会需要计数器或定时器功能;触摸按键部分共有8个按键;请协助评估CY8C5467LTI-LP003  UDB资源否够用,以及是否有其他合适的芯片,谢谢!

看起来CY8C5467LTI-LP003是可用的,但是PSoC4 或PSoC6也可用。最好在Creator里配个原型,编译一下看能否满足要求。

这个显示屏有什么屏?字符?段位?图形?你的想法中UDB是给什么用的?

Hi Roy,

显示屏是段式显示屏,80个seg,2个com;使用UDB可以减少CPU的占用,类似于并行操作,

MCU主要是接收485信号然后在显示屏显示再加触摸按键的功能,请问有相关的例程可以提供么,多谢!

80个seg那么多?例程的话可以在这里https://www.cypress.com/documentation/code-examples/psoc-345-code-examples 找找,这里基本列出了全部PSoC3/5的例程。

Hi Roy,

客户是外配了驱动ic,想法是通过配置UDB,并行操作25个IO口给驱动IC控制信号,想用CY8C5467LTI-LP003 这颗料。Tks!
