stm32f4 tft lcd example in stock

You can refer to the examples under STM32CubeF4 package to see their structure and get inspired from them to configure your files: STM32Cube_FW_F4_V1.21.0\Projects\STM32F429I-Discovery\Applications\STemWin

STM32F429 has also LTDC driver for LCD like that, but this driver we will use later. For now we will use SPI for driving in serial mode and some other pins for controlling.

Remember: This library can also be used, if you are not using STM32F429 Discovery. It can be used in previous STM32F4 Discovery board. All pins can be changed in defines.h file which is included in project.

According to the Setup, the LCD_D2 is connected to the PA15. So if I want to write the DATA to the LCD_D2 pin, first I will select the 2nd bit of the data (d & (1<<2)), and than shift this by 13 using <<13. This will be like adding 2 with 13 to make a total of 15, and that’s where the LCD_D2 is connected to.

Similarly, LCD_D7 is connected to PA5. So to write the data, first we will select the 7th bit of the data (d & (1<<7)), and this time shift it RIGHT by 2 (>>2). This is like subtracting 7-2=5. And that’s where, the D7 is connected to.

The process here remains the same. Except, we have to first select the GPIO Pin, and than shift it according to the position of the LCD Pin, that it is connected to. In the function above, we are first selecting the PB0 pin, and as it is connected to LCD_D0, we don’t need to shift it anywhere. Same for the PB1 also.

Next, we are selecting PA15, and as this one is connected to the LCD_D2, we need to shift it by 13 to the right ( >>13). This process continues for all other pins too.

I"ve written some code to make a FSMC connection between my STM32F407VET6 and a TFT LCD 240x320 pixels. I was checking this several times, however I can"t recognize what"s wrong.

I"m using 16-bit data bus with FSMC_NE1, FSMC_A16, FSMC_NWE, FSMC_NOE. I"ve connected PE6 pin which is FSMC_A22 in FSMC interface. Now I"m wondering weather it can work with such configuration (I mean PE6 pin). All I get is white screen on my LCD as it is in RESET state.

so im trying to make a frequency counter with a nucleoSTM32F429zi and i have a few issuse firstly im using a PWM output through a low pass filter to make a sine wave. that works fine however at the end of the project i have to desplay the frequance on an LCD this is where my problems i have an LCD connected properly. but when the PWM is active there is no output to either putty or the LCD i am also unable to send anymore than a single character at a time and i need a string to show the frequancy. please advise me on what is wrong

I"m using this library but the problem is that I get only two colors at my LCD screen. Black and Purple. That"s because this library is made for 8-bit databus.

It’s time to write about a more complex but interesting connection with the STM32F4-Discovery board. Since I started developing with electronics, I’ve found a lot of applications in which an LCD is needed or can be an added value, specially if it includes a Touchscreen.

Last week I received a 3.2″ TFT LCD with Touchscreen from waveshare, model HY32D. It is based on SSD1289 display controller and also includes a touchscreen interface based on XPT2046 which communicates over SPI link. With a QVGAresolution (320×240 pixels) is enough for many applications and, more important, it is very affordable.

Well, fortunately Waveshare(LCD module supplier) includes some code to drive different kinds of displays and touchscreens. On Waveshare module’s page there is also a very helpful table that indicates the pinout (also the module itself has named pins on bottom side) that helps wiring to the board. Basically I have connected in this way:

The STM32F429 Discovery kit (STM32F429I-DISC1) allows users to easily develop applications with the STM32F429 high-performance MCUs with ARM®Cortex®-M4 core.

The discovery board referenced STM32F429I-DISCO does not support the drag&drop and Virtual Comm Port features. If you are using this board version, you will have to use an external tool (for example the STM32 STLink utility) to program your code .bin file. There is no possibility to use either the printf in your code.

The STM32F429I-DISC1 board includes an ST-LINK/V2-B embedded debug tool, a 2.4" QVGA TFT LCD, an external 64-Mbit SDRAM, an ST MEMS gyroscope, a USB OTG micro-AB connector, LEDs and push-buttons.
