3.5" inch TFT LCD Display Module 480X320 driven with FSMC.
TFT LCD Display Module 480X320 driven with FSMC
I have recently bought a 3.5" inch TFT LCD Touch Screen Display Module 480X320 with a www.mcufriend.com
label on the back side. The display was equipped with an 8bit parallel interface. First I decided to test it with the UniGraphic library using the BUS_8
protocol. The display was very slow but improved when I switched to the PAR_8
protocol. Because I heard about the possibility to use a Flexible Static Memory Controller (FSMC), built into some STM MCU's, to drive LCD's (read/write to LCD's memory rather than to an external SRAM) I thought it would be a fun to try it out.
Below is the brief story of what I did:
- Created a project for my STM32F407VE board in the STM32CubeIDE
- Set the
Clock Configuration
to match the one used by Mbed for the Seeed Arch Max board:
- Selected
FSMC
in theConnectivity
category and configured it as below: - Let the
STM32CubeIDE
generate the code (files). - Created a new program for the Seeed Arch Max target in the Mbed Online Compiler by selecting a
mbed os blinky
template. - Replaced the
main.cpp
with themain.c
content of theSTM32CubeIDE
project. Copy & Pasted
the other files with codes from theSTM32CubeIDE
project to the online compiler project.- Renamed and modified:
"stm32f4xx_it.h" to "stm32f4xx_it_msp.h"
"stm32f4xx_it.c" to "stm32f4xx_it_msp.c" - Added the UniGraphic library to the online compiler project.
- Extended the
UniGraphic
library with aFSMC_8
protocol and replaced theTFT::set_orientation(int orient)
function with the one used bymcufriend
for arduino. - Modified the
main.cpp
as needed.
