How to use FSMC bus to drive ili9325 LCD screen in STM32

This article introduces how STM32 uses FSMC bus to drive ili9325 LCD screen, the content is very detailed, interested friends can refer to, hope to be helpful to you.

After a few days, it was finally lit up. I was very happy to write an article to record it. Poor pure software developers, do not understand hardware and embedded bullshit, related concepts are not very understanding, readers go to search.

Environment:

Stm32f103zet6 Core Board + st-link v2 Emulator + ili9325 LCD Module

Connect:

FSMC bus is a reused GPIO pin, and the corresponding relationship can be found in the data of stm32f103zet6. My connection is as follows:

/ / STM32F103ZET6-> ILI9325

/ / PE0-> LED

/ / PE1-> RESET

/ / FSMC_NE1 [PD7]-> CS

/ / FSMC_A16 [PD11]-> RS

/ / FSMC_NWE [PD5]-> WR

/ / FSMC_NOE [PD4]-> RD

/ / FSMC_D0 [PD14]-> D0

/ / FSMC_D1 [PD15]-> D1

/ / FSMC_D2 [PD0]-> D2

/ / FSMC_D3 [PD1]-> D3

/ / FSMC_D4 [PE7]-> D4

/ / FSMC_D5 [PE8]-> D5

/ / FSMC_D6 [PE9]-> D6

/ / FSMC_D7 [PE10]-> D7

/ / FSMC_D8 [PE11]-> D8
