If itoa function gives you an error, use sprintf instead of itoa as shown below
sprintf(snum, "%d", x);

You need to include stdio.h for this function as shown below
/* USER CODE BEGIN Includes */
#include "stdio.h"
/* USER CODE END Includes */

I'veseen many videos and tutorials about 1602 Display, but this is, by far, the best of them.

Hello sir I have never missed any of your video, your content is amazing I have tried almost all projects, I would recommend you to do a bluepill project where MCU would send a live time data to http server or firebase using GSM(GPRS).

hi, i don't know how to use HD44780_CreateSpecialChar, HD44780_PrintSpecialChar, HD44780_LoadCustomCharacter. Can you show me a example to use it ? Please

[bigcatdairy]

I did it in the exact same way but nothing displayed lol, what could be wrong pl?

[sahilmanihar]

Can you make a video on interfacing dht11 temperature and humidity sensor using STM32 and it's output showing on lcd 🙏🙏

i am using stm32f030f4p6 and I got problem in liquid_crystal_i2c.c in the syntaxe (I changed the source to 0xx...instead of 4xx which means the problem is not here) so what is the problem

[alinavaid]

Hello. I am trying to connect an Geeek Pi LCD to NUCLEO-L053R8 using IC2 interface. I was wondering if the I2C address for this LCD will be the same as the LCD used in the example. I would really appreciate if we can connect, i am working on my senior design project.

Thanks for your guide line. Please guide me how can I modified code for 20x4 lcd

I have a problem that LCD is not displaying. first line of display is on and that's it, do someone had same problem?

[mertali]

I tried it on arduino and it works, but when I try it the way you show, the first 8 digits are fine but the last 8 digits are rectangular. Is there any solution for this?

[arrazyzaid]

Why does it still give an error even though I've followed it from start to finish?

[hacker]

i hope we can drag and drop the .C and .H Files to SRC and Include folder respectively ?

[fatiswealth]

Hi, other than the Ground and Vcc, the other 2 pins does it matter which pin it is connected to? Must it be a ADC pin or just normal GPIO pins will do? :)

[aissatoudieng]

Hello, I am doing a project on STM32 with ADLX345 and LCD display in I2C. can you please help me

[roopesh]

Sir I am using Keil and CubeMX. For me, the folder structure doesn't have Include folder. What to do?

[alifioahmad_raihan]

Sir, I have tried to follow step by step but when compile find an error : make: *** [Core/Src/subdir.mk:37: Core/Src/liquidcrystal_i2c.o] Error 1
How to fix it sir ?
