MCP23016 Applications:

- General purpose I/O expansion for I2C/SMBus applications (like driving ACPI power switches, sensors, push-buttons, keypads, LEDs & fans etc.)
- Power supply applications
- PCs, cell phones, Home Appliance and industrial applications
- Board version tracking and configuration
- Board health monitoring and status reporting
- Multi-card systems in telecom, networking, and base station infrastructure equipment
- Field recall and troubleshooting functions for installed boards

MCP1252/53 is a regulated charge pump that can be used for white LED drive in parallel, the drive capability can be up to 120mA. The control of the brightness of LED can be done through a control signal which applied to /SHDN pin. Only need a small capacitance external capacitor and no inductor is required, so it is very easy to use with no EMI issues.

For drive LED in series, we have MCP1650 boost controller, the voltage output of MCP1650 can up to 100V with 5W power output, so it is easy to drive many LEDs is series, datasheet of MCP1650 been put in Microchip's website, you can get it from website or contact Microchip Taiwan office.

We don't have specific NiMH battery charger at this moment but we have a PIC+MCP1630 solutions for NiMH battery charger, please reference to "教材及講義/2004春季研討會/AIPD New product/MCP1630" to get the presentation material.

我想如果你透過RS232的方式來傳收資料 , PIC都不成問題 , 只不過你可以先了解一些東西 , 如VB傳一筆資料出來時是什麼格式 , 二進制?十進制?還是ASCII?那麼PIC收到的資料時你就會知道怎麼去解釋這筆資料 , 換句話說 , VB那端需要什麼格式的資料收發 , 了解以後 , PIC這一端應該就不是太大的問題了

感謝你們的回應
我會繼續努力的

要怎麼用PIC16877傳送接收VB的程式
或VB傳送接收PIC的指令

呵呵....XD
我是用這網站的資料來做的沒錯....
線路和信號也確認過了。
不過16F86A有時候還是會燒壞，國外的news也提到有這情形。所以PO上來問一下有沒有人有這經驗。
因為JDM比PSTART小太多了，攜帶也方便。但是燒壞幾顆實在心疼，就只好回去用PSTART了.....

這裡有說明

我现在需要使用PIC驱动LCD，其中LCD选用162A，采用4位数据方式工作，应该怎么样驱动 啊？我看过 和调试过许多源文件，但是都不能显示，是什么原因啊？谢谢各位的帮助
