16bit LCD接口问题?请讨论一下。
对于MTK平台
不清楚。
通常应该是取低位
高位不用吧
偶是从NLD0-NLD15通过EMI接到LCD口的,
请问下如果接口接成了16位那么软件里面怎么设置对应的也为16位?
谢谢
For parallel LCD modules, the LCD controller can reuse external memory interface or use dedicated 8/9/16/18-bit
parallel interface to access them and 8080 type interface is supported. It can transfer the display data from the internal
SRAM or external SRAM/Flash Memory to the off-chip LCD modules.
For serial LCD modules, this interface performs parallel to serial conversion and both 8- and 9- bit serial interface is
supported. The 8-bit serial interface uses four pins – LSCE#, LSDA, LSCK and LSA0 – to enter commands and data.
Meanwhile, the 9-bit serial interface uses three pins – LSCE#, LSDA and LSCK – for the same purpose. Data read is
not available with the serial interface and data entered must be 8 bits.
Data and command send to LCM are always through the parallel Nandflash/Lcd interface or through serial SPI/LCD
interface. Sending LCM signals through EMI is forbidden, but the pixel data produced by LCD controller can be
dumped to memory through AHB bus.
