That's the point - to be able to understand even a "simple" LCD project, you need to have worked through the basics of handling GPIO, registers, timing, etc.

But lower nibble can be modified according to our convenience. The question is why we need to modify lower nibble? Well you generally don't but as I mentioned in my previous article that we can connect upto devices on the same line of I2C and let's say we want to connect two different LCDs on the same I2C line, than we can't use two PCF with same addresses and we need to modify one of them.

So how do we modify the address? To change the address we are provided with A0, A1 and A2 pins. By default these three pins are high so the address by default is which is 0x4E. So let's say you connected A0 to ground, new address will be which is 0x4B.

In this manner, we can connect upto 8 LCDs to the same line. As shown in the figure above, first pin of the device is Vss which is pin 1 of LCD. So all you have to do is connect first pins of the LCD to Vss above and rest will connect accordingly. Starting with Vss as first pin, connection is as follows First of all we have to create functions for LCD command and data. The above function will send the command to the device to which our LCD is connected. As we are using 4 bit LCD mode, we have to send command in two parts first upper than lower.

Both parts are sent along enable pin 1 and than with enable pin 0. The above functions ends the data to the device to which our LCD is connected. We have to send data in two parts first upper than lower. In second case data is OR with 0x01 to make only RS pin high and all others low. No comments:.

We will be comparing these micros to each other along with comparing them to the Arduino. You will also get a discount on shipping on your first order.

So, according to the above comparison that I've drawn, let's summarise our findings:. The STM8S, on the contrary, makes its case as a cheap micro but definitely delivers lesser power. Which is what we are going to do in the next steps :. Try out different example sketches which should upload to the board as easily as the Blink sketch did.

Respect project. Similar projects you might like.The time has come for me to try one of the bit ARM microcontrollers available these days.

I'm not going to give up with 8bit world, no way, but I think it is very interesting to expand my knowledge in this area. These microcontrollers have more speed, more peripherals and more capabilities, with the drawback of significant complexity comparing with 8 bit MCU's. As we can see from the graphs above, our microcontroller ranks in the middle, in terms of performance and memory. These charts are screenshots from ST site:.

I must say from the start that I am very satisfied with this board. I like the minimal design, what gives me the freedom to choose how and what devices to connect. Because I do not have yet a dedicated programmer I will go further with first option system bootloader. NOTE: After flashing and running an example you must push reset button to be able to flash another example.

To make it work in Arduino IDE 1. I put here an archive "ready to use" with additions already made for this specific board. I left intact the entire original project structure. Note: These changes are already made in the attached archive.

You just need to unzip the archive content and to put in place. At this point I must admit that I cheated a little Instead I tried to find some tools to compile and run some examples, and set my own way to work with these MCUs. I spent a few days after google: " stm32 toolchain " trying to of guiding me in the multitude of possibilities. There are many No longer talking, I decided to start from groundbecause I want to understand what's going on at low level. There are precompiled versions for WindowsLinux and Mac also source code.

After installation make sure that the bin folder of arm-none-eabi-gcc is inluded in PATH enviroment variable. We can test this with command:. From their description: "This library is a firmware package which contains a collection of routines, data structures and macros covering the features of STM32 peripherals.The LCD display is an important component while interfacing any sensors and displaying the output value. LCD Liquid Crystal Display screen is an electronic display module and finds a wide range of applications.

A 16x2 LCD display is a very basic module and is very commonly used in various devices and circuits. A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc.

The data register stores the data to be displayed on the LCD. Make an exact same connection like this. There are 6 methods by which you can program STM32 Microcontroller. The methods are: 1. STM32duino Bootloader Method 2. Serial Method 3. By using ST-Link Debugger 4. Jlink Method 6. By HID bootloader 2. I have used the first method i. By this method, you can directly upload code to STM32 via usb port.

But before that, you need to install the bootloader in STM Copy this code to Arduino IDE and upload it by any method mentioned above.

Ask A Question Cancel reply.In any embedded project, displaying important stuff on a display unit is very important as it gives the user an easy way to interact with the system. Take your energy meters, weather stations, heart rate monitoring systems and many more.

stm32f103c8t6 lcd

All these projects have a display unit in their final implementation. A simple character display is more than sufficient for displaying important stuff like readings from a sensor, the value of the ADC, status of a relay etc. So, in this project, we will do the same. Since this is a demo for interfacing the LCD module, we will display some sample text just to see the output. But as a refresher, let us quickly have a brief intro of the same. The term 16X2 means that it has 16 columns and 2 rows.

Each column in a row is used to display a character and hence, in a 16X2 LCD display, you can display a maximum of 32 Characters at a time. The LCD module will be configured in 4-Bit mode so that only 4 data pins are used to transmit the data that is to be displayed on the LCD. Coming to the LCD Module, pins 1 and 2 i. Similarly, the pins 15 and 16 i. To adjust the contrast of the LCD Display. Coming to the control pins i. Next are the data pins. We will be using the LCD in 4-bit mode so only 4 data pins i.

D4 to D7 Pins 11 to 14 are used. Connected these pins to B0, A7, A6 and A5 respectively.

The other four data pins i. D0 to D3 can be left unused. If you have completed this basic setup and successfully uploaded a first program Blinkythen you are good to go. If you are switching with power ON, then you have to press the Reset button every time you switch between the modes.
