tft otm8009a 驅動問題

2019-08-14 00:34发布

請問otm8009a裡的初始化函數Lcd_Initialize指令的意思
還有為什麼是用FSMC B模式

以下是程式

#include "stm32f10x.h"
#include "Tiky_LCD.h"

STM32 的FSMC我不是很懂，不过OT8009A的初始化，可以帮你分析一下

有需要3.97寸液晶屏（CPT3.97+OTM8009A）的朋友，可以联系我支持MCU-8/16/24BIT，可用于STM32的FSMC接口，目前数量有2500PCS，提供液晶屏的所有技术支持（初始化，CAD图纸，平台上的调试）
