How do I communicate with an LDC screen with I2C?

25 Apr 2023 by CD416

Good morning, I am doing a project for my school, for this I have to communicate with an LCD screen 2x16 (I2C). I use CubeIDE software and NUCLEO-STM32F411RE development board. I have already my program, there is no error or warning. however the...

I would go back to the site you found the code on, and ask there - they will at least n=know what the processor board is expecting to be connected to it, and how. They may even have used the same LCD and have a good idea of it's interface...

Check the hardware connections (if you have a logical analyzer, or an oscilloscope, then check the I2C signals as well). Then try to run the sample code as it stands. If it works then start to adapt it to your needs.

Why is the button on the STM32 micocontroller not responding once I am in the while loop?

18 Aug 2023 by Member 16074047

I am trying to make a program where two different LEDs are blinking every 1000ms but I also want to be able to exit the loop anytime I want. Once I get in the while loop, the button on the STM32 is not responding. I am working with STM32CubeIDE...

Why is the button on the STM32 micocontroller not responding once I am in the while loop?

18 Aug 2023 by OriginalGriff

You have 5 Delay statements in there: each of them probably waits around 1 second - so unless you hold the button down for at least 5 seconds, probably longer, there is no way that the code will see the button being pressed since it reads the...

Why is the button on the STM32 micocontroller not responding once I am in the while loop?

18 Aug 2023 by Andre Oosthuizen

You need to add a pause within your loop because your current loop is continuously running and not giving the system a chance to process other events, including button presses - void Screen1View::relay_1() { if (toggleButton1.getState()) { ...

How can I transfer numbers that I input on my STM32 controller into a variable in cubeide?

24 Aug 2023 by Mike Hankey

The STM32H750B-DK, and most STM32 devices do not have any EEPROM available so you will have to add a EEPROM chip to persist the data you require. MicroChip also has a chip, the 47C04-E/P that is a RAM chip that automagically backs up the RAM...

Depending on your needs, you may also implement emulated EEPROM in flash. See How to use EEPROM emulation on STM32 MCUs.

27 Aug 2023 by OriginalGriff

The error message is pretty clear: globals.h: No such file or directory And it means what it says - the file globals.h is not in any location that the compiler is checking. Start by finding the file, and compare its location with the rest of your...

First, you would be better served by asking your question in a forum dedicated to the hardware you're using, at ST Community[^]. Next, you make no mention of what pins you connected the LCD on, which LCD it is, what it's requirements are, and...
