STM32F4 Discovery board - Keil 5 IDE with CubeMX: Tutorial 21 - TFT LCD ili9341 (using FSMC)

[@drewh0208]

THANK YOU SO MUCH! I got it working with the DevEBox STM32F407 breakout board with the 16-bit-interface TFT_320QVT_9341 display board! With your linked code and some tweaks for my setup I get exactly the same thing shown at 16:41! I had to change the data address 0x6004000 to 0x6002000 to use with my particular Register Select A16 setting per 6:47 ("Understanding FSMC addressing" paragraph). I also think that after HAL_GPIO_WritePin(RST_GPIO_Port, RST_Pin, GPIO_PIN_SET); in main.c there should be added another HAL_Delay(10); after raising the Reset line, but doesn't seem necessary from experimentation. I made a couple more tweaks to change to a 16-bit interface, changing *(__IO uint8_t *) to *(__IO uint16_t *) in the SendCommand/SendData functions, and adding another SendData function for 16-bit color data and editing the printImage function to combine the upper/lower bytes. 3:34 changing these timing settings from the 15/255/15 default settings sped up the drawings a lot. My circle function still seems a liiiitle bit slower than what's shown in the video. www.amazon.com/gp/product/B081BCXST2/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 www.amazon.com/DIYmalls-ILI9341-Display-Resistive-320x240/dp/B086ZK6VG5/ref=cm_cr_arp_d_product_top?ie=UTF8

Thank you so much for describing the FSMC and ILI9341 and how to use it in Cube. I am using an STM3220G Eval board which uses a 3.2" LCD and the ili9325 drivers but its very similar to your driver in the way of functionality. Thanks again. :)

Hi, Is it possible to connect a TFT LCD ILI9225 or any other with an ISP to a NUCLEO unit, or whether there is a library for this TFT LCD. I am also interested in what sample FFT for NUCLEO boards. I use NUCLEO-144, STM32F767ZIT. best regards

[@mutexembedded2206]

LMM LIGHT MY MUSIC Yes, it is possible of course.. as long as you have Parallel interface (8bits or 16 bits). You need to do the initialization sequence of the ili9225; you effectively need to have your own LCD driver but the FSMC Write concept is the same. Good Luck

Great tutorial, the LCD works great except for me unable to write some specific colors, like 0x001F turns the screen white and I can't do anything unless I reset the STM board. Would you happen to know why this happens?

[@mutexembedded2206]

Hi, Sorry for later reply.. that could be overclocking or long wires

[@slojanko]

Thank you, the newest version of CubeMX has output speed values along with FSMC so I played with those a bit. I also switched to TrueSTUDIO which is a free and without limits alternative to uVision.

[@slojanko]

So I'm looking at the datasheet of the display and was wondering if it was possible to write the entire frame to the display, then request a refresh to avoid the huge tearing I'm currently having. There seems to be no mention of this being possible, would you know anything about this?

I'm using PC4-11 as the data lines, but you can take any consecutive pins from one port. Best would be to use PC0-7 for example since no shifting is required. Writing to ODR would be faster but only if you dont have to mask other pins from the same port.

Depends. SPI uses 3-4 pins while FSMC uses over 10 pins. However FMSC can probably transfer at much higher rates since it's a parallel interface.

Hello very good videos I have an lcd 3.2inches with ILI9341 and interfaces of 16bit LCD register select is A18 modify *(__IO uint16_t *)(0x60080000) data; and it works I see the color blue, but I can't change the colors when I write text or a figure the color is wrong I wanted to ask you that something else I have to modify so that the colors are displayed correctly with 16bit interfas thank you very much

[@hooligun90]

Hello, I have the same problem. Did you find a sollution for it?

[@psyduckel]

Hi there MYaqoobEmbedded, Would the tutorial work using the NUCLEO-L476RG, if not what would you need to change? Thanks for any help.

[@mutexembedded2206]

Hi, No, the L476 does not seem to have an FSMC NOR interface.

[@psyduckel]

Do you have any recommendations on how to get an TFT LCD ILI9341 screen working on the NUCLEO-L476RG?

[@mutexembedded2206]

Psyduck Hi, You can replace FSMC Read/Write functions with SPI read/write .. but needs to set your display to spi mode.

[@psyduckel]

MYaqoobEmbedded thanks for the reply, unfortunately the screen I'm using does have spi :'(

[@mutexembedded2206]

Psyduck You can try implementing the parallel interface timing yourself; Set the data on 8bits or 16 bits pins and trigger WR pin to write data to lcd.. There are a lot more details about this on lcd data sheet.. Just google lcd parallel interface 8080

[@wuerike]

Great video! I have a stm32L4 and it havent the FSMC option, could you teach how to do it by the SPI interface?

[@mutexembedded2206]

Hi, Modify Read/Write functions to use SPI Write&Read instead of FSMC Read/Write,, as simple as that.

[@mrudulaamirapu2472]

Yes, I too would like to know how to do the same. If you can, please give a little more information. Thanks!

[@mutexembedded2206]

Mrudula Amirapu Hi, Sure.. I will explain to you how to do that with some coding later today.

[@mrudulaamirapu2472]

Thank you very much! I find your tutorials very helpful! :)

[@mutexembedded2206]

There are 4 changes you need to make to replace FSMC with SPI: Step(1): The wiring of LCD SPI interface is different MBED Display + 3,3V 3,3V GND GND MOSI SDI MISO SDO SCK RS CS CS Reset RST DC WR/SCL GND RD Step(2): Need to enable a Digital Output pin DC pin (Data/Command) - At the start of ILI9341_SendCommand() function, set DC to LOW. - At ILI9341_SendData() function, set DC to HIGH. Step(3): replace "*(__IO uint8_t *)(0x60000000) = com;" in ILI9341_SendCommand() function with HAL_SPI_Transmit() function and transmit the command byte. Step(4): Similarly replace "*(__IO uint8_t *)(0x60040000) = data;" in ILI9341_SendData() function with HAL_SPI_Transmit() function and transmit the data byte. So, the modified functions should look something like this: ILI9341_SendCommand(uint8_t com) { HAL_GPIO_WritePin(DC_Port, DC_Pin, 0); HAL_SPI_Transmit(&hspi, com, 1, Timeout); } ILI9341_SendData(uint8_t data) { HAL_GPIO_WritePin(DC_Port, DC_Pin, 1); HAL_SPI_Transmit(&hspi, data 1, Timeout); } That's pretty much it,, Good luck

[@hoangphamtranminh8344]

Is it a possible to touch on screen? Because i see you only display the pic on screen. Hope you answer my question. I need to know because i’m ready to buy that screen. Tks

[@mutexembedded2206]

Hi, Yes, this one has got resistive touch, but touch pins (x+, x-, y+, y-) are shared with communication pins, look that up. There is a good alternative too, that works with this library: www.mikroe.com/tft-proto-board Good luck

[@hoangphamtranminh8344]

Tks for your quink reply but I still have some question. You said that touch pins are shared with communication pins. So you mean that is impossible to do touch action on that screen with stm32f4, isn't it? Hope you rep soon because i'm ready to buy that touch screen (in you vid) to use for kit stm32f4 :D

[@mutexembedded2206]

Hi mate, What I meant by touch pins are shared at this particular module is that, X+, X-, Y+, Y- are connected directly to LCD_WR, LCD_RD, and so on. So in order to take Touch reading, you need to stop communicating to the LCD temporarily and convert LCD_WR pin from Output to Input in order to read touch value. But there are better ili9341 screen boards where touch pins are separate.

[@edwardsoto3279]

you will obtain a better performance using the HAL FMC library

[@kinsi55]

Thanks a lot.

[@nicknagy8903]

I'm using this with an STM32F767ZI and getting weird results. It looks as if the functions and examples are ALMOST working. For example, printImage(50, 50, 80, 130, myImage, sizeof(myImage)) creates an image that's way too thin, in the bottom corner, and looks discolored. Or Fill(COLOR_RED) will create some red pixels at the edge but not cover the screen. I've disabled the FMC FIFO, the FMC clock SHOULD be at 168MHz, I'm using single jumper wires between each connection to try and minimize signal travels, and I've checked the connections multiple times. I have also tested in Arduino with at ATMega and a different class-distributed library for the TFT, and have verified that with that code the TFT works fine. So I know that the problem must have to do with the STM32/Nucleo, not the TFT itself. I can't figure out what I am doing incorrectly. I'm using TrueSTUDIO instead of Keil, would that make a difference??

مرحبا محمد Showing content on half of the screen only is usually caused by data bus width; if you are using 8 data lines and LCD is set to use 16 data lines mode, it will only fill half of the screen. Thanks

[@mutexembedded2206]

Amfibrachy Hello! Good to hear that you're finding the videos helpful.. For the ST7735 LCD, it should not be too hard to look at an existing code alongside with its datasheet to create a driver for it. I have not worked on this before, but you should be fine if you spent sometime on it. Good luck

Thanks you. That's my laziness I suppose )) I haven't watched all your videos yet. So do you think if i'll follow all of them, I'll be able to make the display work without any library, all on my own + CubeMX?

A ILI9341 2.4 keil Project configured with cubemx , gui created with GUIBuilder, and touch screen code To add further you can really demostrate the use of gui development tool like "μGUI - free Open Source GUI module for embedded systems" [embeddedlightning.com/ugui/] EasyGUI - Easy GUI for microcontrollers [github.com/MaJerle/EasyGUI] littlev - [littlevgl.com/porting] Since these three tools are free of cost and really contributes a main step of product development thanks
