找了一個 AN510 給你參考一下:

AN510 : Implementation of an Asynchronous Serial I/O

http://www.microchip.com/stellent/idc ... eId=1824&appnote=en010973

The PIC16C5X series from Microchip Technology Inc., are 8-bit, high-speed, EPROM-based microcontrollers. This application note describes an implementation of an asynchronous serial I/O using a PIC16C5X micro-controller. These microcontrollers can operate at very high speeds with a minimum cycle time of 200 ns @ 20 MHz input clock. Many microcontroller applications require chip-to-chip serial data communications. Since the PIC16C5X series has no on-chip serial ports, serial communication has to be performed in software. For many cost-sensitive high volume applications, implementation of a serial I/O through software provides a more cost effective solution than dedicated logic. This application note provides code for the PIC16C5X to simulate a serial port using two I/O pins (one as input for reception and the other as output for transmission).

主要針對將2組ADC轉換出來的訊號，藉由RS232傳輸至PLC(Power line carrier) module 解碼，

PIC12只要能以串列傳輸方式將ADC傳送既可。

本身熟C語言但可能要以Assembly撰寫

謝謝您

PIC12 沒有 UART Module，所以傳送只能用軟體模擬方式用 I/O 傳送。請告知傳送的 Protocal ? C or Assembly?

不好意思~

想請教有人有用過將PIC12擷取ADC資料藉由RS232傳輸嗎?

目前AD取值OK但是不會用RS232傳輸，

可以提供我相關參考資料嗎?
