Since I have no money to fabricate PCB, I have to go to school components store and collect them. My friend Terrence help me a lot, who gave me 18F4550. For others components, I have to buy them from market.
The test result: all pass, including debugging and downloading.
Before this ICD2, I tried "The simplest ICD2", but it failed under MPLAB 7.42.
In addition, the Vpp has some problem: it can not pull MCLR down to ground, (MCLR is pulled-up to Vcc with 10K resistor in the circuit.)
It only spend me 9 Singapore Dollar (around 5.6 US dollar).

因为自己没有资金去做PCB。
于是,自己就从学校里面拿了很多元器件,然后朋友Terrence帮忙给了18F4550,其他少的东西就去买了.
测试结果是:一切顺利,除了Vpp有点问题,可能这和设计有关吧。
