I2C 的 Communication Protocal 裡資料的傳送都是以 8-bit 為單位，他無法直接抓 10-bit，如要抓 10-bit data 就要分成兩次讀取或使用 Sequential Read 方式讀取。

[I2C 問題]--
請問如何一次抓 10bit的值[ADC],目前我只能抓取8 bit的值 ******************************************* int EEPROM_ByteWrite(unsigned char CMD , unsigned char Addr , unsigned char Data ) 1.當我將 unsigned char Data>改成 unsigned int Data 編譯時會發生錯誤 2.當連抓2次 data 卻無法成功() MasterWriteI2C(Data>>8) // high byte data MasterWriteI2C(Data) // low byte data ex:265 high byte data=抓取為0,不是2...?? low byte data=抓取65,OK ****************************************** chip型號--> dspic30f6010A C語言 韌體I2C I2C Master & Slave ************************
