只是一个简单的问题。我正在使用一个新的CY8CKIT-042 PSoC4先锋套件。有些事，我无法在它的工作（如一个简单的16x2液晶显示），尽管我已经试过了，我知道尝试一切。我使用的创造者没有专家（3），或接受，或'包'，但我真的达到年底的事情去尝试。作为最后一招，我拿出放大镜和阅读部分的psoc4芯片。它是。。。CY8C4245AXI-83ES我的问题…“ES”代表什么？如果是我想它的意思，然后我用一个“工程样品”这一局。（或者试着用一个。）有人能对此有所启发吗？如果_is_工程样品（我已经购买了两（2）先锋套件都有'的部分上），那么这就可以解释为什么我有困难。谢谢。詹姆斯 以上来自于百度翻译 以下为原文Just a quick question. I am using one of the new CY8CKIT-042 PSoC4 Pioneer Kits. There are some things that I am not able to get working on it (like a simple 16x2 LCD display), even though I have tried everything that I know to try. I am no expert using Creator (3.0), or the PSoC, or the 'kit', but I am really reaching the end of things to try. As a last resort, I got out my magnifier and read the Part Number on the PSoC4 chip. It is... CY8C4245AXI-483ES My question... What does the 'ES' stand for? If it is what I think it means, then I am using an 'Engineering Sample' part on this board. (Or trying to use one.) Can someone shed some light on this? If it _is_ an Engineering Sample (and I have purchased two (2) Pioneer Kits - both have 'ES' parts on them), then this may explain why I am having difficulties. Thanks. James
