想請問各位板大
SPI的library裏的OpenSPI() 有些指令不太明白 Framed SPI support Enable/Disable, Frame Sync Pulse direction control, Secondary Prescale select, Primary Prescale select 不太懂得這些指令在控制些什麼動作 還有SPI傳輸中有CS腳位 不是要制定嗎(拉低準位) 動作才能輸出 怎看不到OpenSPI()沒它的指令 只要制定好library裏的OpenSPI() 和ConfigIntSPI 就可以讓兩塊晶片採取MASTE和SLAVE的狀態嗎 PS:已經查過spi.h的檔案
