Honored ContributorThe problem of SRAM
Hi!
I have succeed to display a image on the LCD through my LCD_CORE,thank you for your help. But I still have a problem about the SRAM,The data bus of my SRAM is 16 bit,so I think the data I write to the SRAM which shoud be 16 bit at a time and the address should be added 2 everytime.but to my surprise in my code the data must be 32 bit and the address must be added 4 everytime which are right.and the datas I read from the address,address+1,address+2,address+3 which are same. is there anyone can help me? thank you!2 Replies
