stm32f103 tft lcd library factory

For any microcontroller project, interfacing a display unit with it would make the project a lot easier and appealing for the user to interact with. The most commonly used display unit for microcontrollers is the 16×2 Alpha numeric displays. These types of displays are not only useful to display vital information to the user but can also act as a debugging tool during the initial developmental stage of the project. So, in this tutorial we will learn how we can interface a 16×2 LCD display with the STM32F103C8T6 STM32 Development board and program it using the Arduino IDE. For people who are familiar with Arduino this tutorial will just be a cake walk since they both are very similar. Also to learn more about STM32 Blue Pill Board follow our getting started tutorial.

As told earlier the Energia IDE provides a beautiful library which makes the interfacing a piece of cake and hence it’s not mandatory to know anything about the display module. But, would didn’t it be interesting to show what we are using!!

Out of all these 16 pins, only 10 pins are to be used mandatory for the proper working of the LCD if you want to know more about these LCD display jump to this 16x2 LCD article.

As you can see the complete connection is made over a breadboard. We need a FTDI board to program the STM32 Microcontroller. So similar to our previous tutorial, we have wired the FTDI board to STM32, the Vcc and ground pin of the FDTI programmer is connected to the 5V pin and ground pin of the STM32 respectively. This is used to power the STM32 board and the LCD since both can accept can +5V. The Rx and Tx pin of the FTDI board is connected to the A9 and A10 pin of the STM32 so that we can program the board directly without the boot loader.

Next the LCD has to be connected to the STM32 board. We are going to use the LCD in 4-bit mode, so we have to connect the 4 data bit pins (DB4 to DB7) and the two control pin (RS and EN) to the STM32 board as shown in the STM32F103C8T6 LCD interfacing circuit diagram above. Further the table below will help you in making the connection.

As told in this tutorial we will be using the Arduino IDE to program our STM32 Microcontroller. But, the Arduino IDE by default will not have the STM32 board installed, hence we have to download a package and prepare the Arduino IDE for the same. This is exactly what we did in our previous tutorial getting started with STM32F103C8T6 using Arduino IDE. So if you have not installed the required packages fall back to this tutorial and follow it before you continue here.

One noticeable advantage of using Arduino for programming our microcontrollers is that Arduino has readymade libraries for almost every famous sensors and actuators. So here we start our program by including the LCD library which makes the programming a lot easier.

In the next line we have to specify to which GPIO pins of the STM32 we have connected the LCD display control and data lines. To do this we have to check our hardware, for ease you can also refer to the table given at the top which lists the pin names of LCD against the GPIO pin of STM32. After mentioning the pins we can initialise the LCD using the LiquidCrystal function. We also name our LCD as “lcd” as shown below.

Next we step inside the setup function. Here first we have mention what type of LCD we are using. Since it is a 16*2 LCD we use the line lcd.begin(16,2). The code inside the void setup function gets executed only once. So we use it to display an intro text which comes on the screen for 2 seconds and then gets cleared. To mention the position where the text has to appear we use the function lcd.setcursor and to print the text we use the lcd.print function. For instance lcd.setCursor(0,0) will set the cursor at first row and first column where we print “Interfacing LCD” and the function lcd.setCursor (0,1) moves the cursor to second row first column where we print the line “CircuitDigest”.

After displaying the intro text we hold the program for 2 seconds by creating a delay so that the user the can read the intro message. This delay is created by the line delay(2000) where 2000 is the delay value in mill seconds. After the delay we clear the LCD using the lcd.clear() function which clears the LCD by removing all the text on LCD.

Finally inside the void loop, we display “STM32 –Blue Pill” on the first line and the value of seconds on the second line. The value of second can be obtained from the millis() function. The millis() is a timer which gets incrementing right from the time the MCU is powered. The value is in form of milli seconds so we divide it by 1000 before displaying it on our LCD.

Make the connections as show in the circuit diagram and use the code given below on Arduino IDE. Go to tools and make sure the right board is selected as done in getting started tutorial. Also, before uploading the program make sure the boot 0 jumper is set to 1as shown in the image below and press the reset button. When the upload button is pressed is code should get uploaded and the message will be shown on LCD as show in the image below.

This is just a simple interfacing project to help use the LCD display with STM32 board, but further you can use this to build cool projects. Hope you understood the tutorial and learnt something useful from it. If you had faced any problem in getting it to work, please use the comment section to post the problem or use the forums for other technical questions. The complete working of LCD display with STM32 can also be found as a video given below.

This second article in the series of documentation-by-example posts will present a C++ driver for 320×240 (QVGA) TFT LCD panels that have an ILI9325 controller built in to them. This driver is included with my open source stm32plus C++ library and this article will show you how to use it with the STM32F103* ARM Cortex M3 microcontroller family running at 72Mhz. As of stm32plus 2.0.0 the driver is fully compatible with the STM32 F4 series of microcontrollers.

I like Ilitek controllers. They’re consistent across the range, they’re well documented and they’re easy to program if you’re familiar with TFT controllers, which I am.

The schematic for the STM32 dev board documents the pinout for the TFT panel. Helpfully, the port numbers are annotated as well as the function of each pin. 16 data lines are broken out, so that implies we’re talking to the controller over its 16 bit bus (it has 18-bit, serial and RGB capabilities as well). Register-select (/RS), chip-select (CS), read (nOE) and write (nWE) are all there. There are additional pins for the reset line (RST) and the backlight. A pleasant surprise is the presence of the touch-screen interface on SPI1 up at the top right; we’ll be kicking the tires of the ADS7843 touch screen IC in a future article.

This dev board plays host to the STM32F103VET6 MCU. The V in ST’s nomenclature means that the device has 100 pins. Those of you that are familiar with the limitations of the 100 pin device will know that means that the Flexible Static Memory Controller (FSMC) only has one 64Mbyte NOR/SRAM bank at address 0x60000000. That’s fine, it gives me the chance to show stm32plus addressing a different bank than the usual #4 that I use on the STM32F103ZET6 board I use most often.

Here’s the code used to initialise the LCD. When this code has completed the LCD will be reset, initialised with your chosen colour mode, gamma and orientation and ready to use.

That’s all there is to it. If you’ve also read my previous article on driving the HX8347A controller then this will all look familiar. That’s because stm32plus hides away all the device-specific details and presents you with a unified interface for controlling graphic devices. Here’s a quickie image taken from the rolling demo. As usual the camera is less than kind to the TFT. The actual display is sharp and contrasty.

We declare an Fsmc8080Lcdtiming object that takes care of the timing details. The two parameters are the address setup and data setup times in HCLK cycles. At full speed the STM32F1 has a 36MHz FSMC bus and the STM32F4 has a 60MHz bus. Therefore the timings may be different for each MCU if the bus is faster than the panel.

Our example initialises it in portrait mode, 18 bit colour (262K). If you take a look at TftInterfaces.h you will see that following modes are available:

The predefined drivers are just C++ typedefs that bring together the necessary combination of template instantiations to create a coherent graphics library.

I found the TFT screen and Uno on Banggood.com about a month ago and over the weekend I was messing with the pair and found the tftbmp draw code in the demo.. I extended it with the ability to read any bmp file on the SD card.. so all you do is put your bitmaps on the SD and plug it in.. Having to add/edit/recompile/reload the Uno everytime is BS... Here is my code:

The LCD I am using is a 2.8″ TFT LCD with SPI communication. I also have another 16-bit Parallel TFT LCD but it will be another story for another time. For this post, let’s focus on how to display what you want on the 2.8″ LCD. You can find all details about this LCD from this page:http://www.lcdwiki.com/2.8inch_SPI_Module_ILI9341_SKU:MSP2807

First thing first, this LCD use SPI as the main communication protocol with your MCU. For STM32 users, HAL Library has already implemented this protocol which makes this project easier for us. But, a little knowledge about this protocol does not hurt anyone. SPI is short for Serial Peripheral Interface which, aside from two data lines, also has a clock line and select lines to choose between devices you want to communicate with.

This LCD uses ILI9341 as a single-chip SOC driver for a display with a resolution of 240×320. More details can be found in the official document of ILI9341. But the most important thing is that we have to establish astart sequencein order for this LCD to work. The “start sequence” includes many other sequences which are also defined in the datasheet. Each sequence starts when you send a command to ILI9341 and then some parameters to follow up. This sequence is applied for all communication between MCU and ILI9341.

For this project, I recommend using theSystem Workbench for STM32for coding and building the code. After installing and open the program, go to the source code you have just downloaded and double click the.cprojectfile. It will automatically be open in your IDE. Then build the program by right click on the folder you just open (TFTLCD) and chooseBuild Project. Wait for it to finish and upload it to the board by right clicking the folder, choose Run As and then clickAc6 STM32C/C++ Application. And that’s it for running the example.

The most important library for this project is obviously the ILI9341_Driver. This driver is built from the provided source code in the lcdwiki.com page. I only choose the part that we need to use the most in many applications like writing string, displaying image and drawing symbols. Another library from the wiki page is the TOUCH library. Most of the libraries I got from the Internet were not working properly due to some adjustments to the original one.

To draw symbols or even display images, we need a “byte array” of that image or symbol. As an illustration, to display an image from a game called Transistor, I have a “byte array” of that image stored in a file named transistor.h. You can find this file in the link below. Then, I draw each pixel from the image to the LCD by adding the code in the Display_Picture() function in the Display folder.void Display_Picture()

The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.
