Great, that helped a lot! Thx m8 ! After adapting Ports / SPI to my HW config it worked instantly like a charm🤩 ('F401 black pill clone + 2.8" TFT with touch controller) Allow me some technical remarks (not critisism at all, but maybe helpful): a) Most chinese display of this type have a 3.3V LDO Onboard, so I would suggest to connect the VCC Pin to 5V. With this aproach the power burden on the MCU board LDO is significantly reduced ("load sharing" on 5V line). (But always check datasheet and jumpers first!) b) The ILI9341 datasheet states a "SCL" (aka SPI SCK) clock period of min. 100ns -> 10MHz max. so i recommend to check the SPI Baudrate result and adjust the prescaler value accordingly. Even if it may work at higher clock rates it may become instable (over temperature typically). Keep up your great work! Greetings from actually quite snowy☃ germany...
Thank you very much! Tried and it worked. I have redone it for SPI2 as planning to keep PortA for other purposes. now i will try to learn making menus and use touch buttons.
Hey, i followed your instructions but i can only change the background color with ILI9341_FillScreen function, other functions do not work for me :( , can you help please? im using 2.8 tft spi 240*320 v1.2 lcd with bluepill
Hello, thank you for this project I made a font using the GLCD font creator software, but it is not displayed correctly because of the "offset of character". How can I extract this number for my font? How did you calculate the offset value for your font?
To get my MCU working at maximum CPU speed I had to enable FIFO on the DMA parameters. Without it I had to reduce the HCLK and FCLK by 2, from 168 MHz to 72 MHz else the LCD bitmap and data was being corrupted at times, rectangles not filling the whole area mainly. Reading the datasheet I see that only with FIFO does the data get packed and unpacked to "maximise" bandwidth, but why is FIFO enabled so necessary to make this work reliably?
You really helped and the Library works great. You left some Instructions on how to make new fonts using GLCD font creator. But at point 9 where you instructed to change the offset, width, height, bpl. Height and width are clear (They are given in the title). But where do i get the Offset and BPL values from?? And what even do these. I need some help here ty!
Library creator's GitHub Repo is at github.com/eziya/STM32_HAL_ILI9341 He says about fonts I wanted to make it support diverse fonts so I adopted character functions from SPI_TFT_ILI9341 library. As it supports C font array created by GLCD Font Creator by MikroElektronika. www.mikroe.com/glcd-font-creator Please refer to the following link to get more details about fonts. os.mbed.com/users/dreschpe/code/SPI_TFT_ILI9341/
i tried to edit the libary with init code for the ST7796S, however i cant get the display to init properly. any idea how i can port a libary to stm32cube ide?
Hello, i have 2 questions. At first how can i clear the LCD ? I didnt find the clear command , and the second one is :can i put the logo of this lcd or not ? Thank you very much .
Thank you, this is very informative, well done and works quite well. However, I noticed that although there is four fonts included in your source code all these fonts are very narrow and I wanted to use a wider bold and larger fonts but I tried to import other fonts from the Adafruit GFX font library but they did not work. Your font set for each font starts with the first four bytes with byte values as follows: Offset, Width, Height and BPL (which I have no idea as to what this one is) Do you have any recommendations as to how to use bigger or different fonts with this code? Are these fonts in your source code considered to be scalable fonts?...Thank you
Thanks. I did not create this library. I found it in public github repository. The author explains how to create new fonts at github.com/eziya/STM32_HAL_ILI9341 I am sorry to say that I haven't tried it myself to create a new font yet. Please try the above link for new fonts.
I tried doing the same thing, but when I am loading the code, the color is getting filled only at the left edge and not on the complete screen. I am using 3.2" TFT, so do I need to make any other changes?
I'm starting with the STM32.. Excellent tutorial. I followed this video and programmed the Blue Pill well. Everything fine with STMCube IDE as expected and the TFT performed well too. I tried again with a Black Pill I have (STM32F401CCU6) but the debug hammer gave me 6 errors like: 'MX_SPI1_init' used but never defined. Can you comment about sommething I must do different with black Pill? Thank you.
Very useful demo, thanks! Sadly I cannot get it to work with a 407VG Discovery board, I´ve checked trough everything several time, using SPI2, changed the clock speeds to match, checked with a scope on the board, so the signals look good, there is some noise on the reset line, I´ll add a capacitor to VCC 5v input on the LCD. The v1.0 red lcd has 5-3v regulators, so I think 5v in will help with the noise. Fingers crossed!
Yeah!! As soon as I added a 470uF capacitor to the VCC-GND 1-2 pins on the LCD, it started to work! Note: The Chinese schematic also says: Power supply selection: When the external VCC input is 5V, J1 is disconnected When the external VCC input is 3.3V, J1 is shorted

I had some problem with these code, everything is ok but if the main() has the funtion "ILI9341_FillScreen" and then it doesn't work, i do with stm32f103c8 also, Thank you .
@@NizarMohideen Of course i do with ILI9341_FillScreen(WHITE); My mean if i have this funtion in my main code, it doesnt work, if the main code doesn't have this funtion, it work well, thanks.
Good video, very didactic. I tested with exactly same board (STM32F103C8T6) and it worked perfectly, but if I turn the board OFF and ON again, I don't have any image on the display (but the blink LED still working). If I program the board again the display works, but I can not restart it. Is there something related with RAM memory or display? Any idea? Thanks!
Hi Nizar, excellent tutorial! I've been looking for a way to communicate with you because I have a problem: In the file ILI9341_STM_Driver.c in the function DrawColorBrust(); There is a BrustBuffer[BufferSize] declaration that gives me problems, since it requires the number of elements to be a constant value, I think it could be due to the version of my compiler, but I see that it doesn't give you any problems. I have solved it halfway, always setting the BURTS_MAZ_SIZE value but this breaks the rest of the functionality, any ideas?
Well, I already found my answer. With versions prior to C99 it is not possible to declare an array with a value that is not a constant, so I have tried to "solve" the problem with the not very recommended way of using dynamic memory with malloc(), but even so, it still fails when painting the backgrounds of the characters. What surprises me the most is that in theory the IAR is using C11. If I manage to fix it, I will update it here.
Can I interface this ILI9341 TFT Display with my STM32F401 Nucleo-64 development board using the same drivers and code? What would be the interface protocol, parallel or SPI? Also, can we write & display this "HELLO WORLD" text in bold and bigger font?
You can select SPI1 and three GPIO_Output pins for CS, DC and RST pins Change ILI9341_STM32_Driver.h file according to the pin section as shown below /* PIN Configuration */ #define HSPI_INSTANCE &hspi1 #define LCD_CS_PORT GPIOB #define LCD_CS_PIN GPIO_PIN_10 #define LCD_DC_PORT GPIOB #define LCD_DC_PIN GPIO_PIN_0 #define LCD_RST_PORT GPIOB #define LCD_RST_PIN GPIO_PIN_1 Configuration → Parameter Settings of SPI, change prescalar (for Baud rate) to 4 If it doesn’t work, Change prescalar (for Baud rate) to a different number Available Fonts are FONT1, FONT2, FONT3 and FONT4
The library creator named eziya in github used to display picture as well. He displayed a while color tiger image called snow_tiger.h It is available in github.com/eziya/STM32_HAL_ILI9341 I don’t know how to create another picture in this format. Thanks
Thanks you it works. I tried using it on Arduino UNO with 5v > 3.3V converter but i get only white display. I thougth display is broken. But i still don't know why it doesn't work on Arduino
I haven’t tested it with F401CC but I think you can use it with F401CC. The library creator named eziya in github used it with F407VG, I simply changed #include "stm32f4xx_hal.h" in header files to #include "stm32f1xx_hal.h" for F103C8 and it worked. Try by changing it back to #include "stm32f4xx_hal.h" in ILI9341_GFX.h and ILI9341_STM32_Driver.h and see. Thank you

I figured out. It needs a delay before ILI9341_Init(); because the microcontroller is faster than the display.
