E0 rI would like to give a brief overview of a couple of parts that Cypress has since 4 Z7 G2 u: L, e/ _+ kintroduced that are sure to be huge successes on future designs.

再下還有幾個疑問就是 ; F8 O( Q$ P: ~; T: q) h4 h9 M1 L在下正在用的PSoC Express把元件都模組化了 / i" L' U& r3 _5 c& B" B2 W想請問一下就是說這本書的內容是否還適合在下使用4 g) k" [0 Z3 L5 e0 w
