1.2538支持SPI接口吗?看手册说的是SSI
关于SPI接口的定义,SCK:PA2,MOSI:PA4,MISO:PA5,
2538作为主,去驱动从设备,上面的引脚分配可有问题?
#define BSP_LCD_SCK BSP_SPI_SCK //PA2
#define BSP_LCD_MOSI BSP_SPI_MOSI //PA4
#define BSP_LCD_MISO BSP_SPI_MISO //PA5
2.2538的I2C接口对应的引脚是哪两个引脚?手册里没找到
3.我现在准备做的也是用2538去驱动网络芯片W5500,SPI接口,
但是我看到下面的帖子2538的SPI接口有问题,不知道是否可行?
