60. STM32CubeIDE LCD 1602 Display. Parallel 16x2 with STM32F446RE

STM32 Nucleo for beginners

You can use without 100 Ohm resistor for only short period of time to test.
You must use a 100-330 Ohm resistor if you want to use for long time.🚦

✅✅✅ working without any issue I'm using with STM32G030 MCU good thing compare to other library it print Integer directly with separate function without converting it into string. Thanks for reducing our work load.

I'm curious if it goes well, because the author is connecting VDD to 5V and according to Datasheet of the LCD, the MIN Input High Voltage is 0.7VDD what is 3.5V, but as known the GPIOs only deliver 3.3V.

Hi, I followed your guide but I've a problem with display: the left side is less visible than the right side. I tried with from 10 - 330 Ohm resistor but nothing has changed

Hi Sir,

I watched both F1 and F4 videos. Could you please tell if the lcd.c and lcd.h files/code would be same for all stm32 versions, and just change that #include part?

[Hammad]

One more question please sir.

If we have done everything like this, and want to print some sensor data also in while(1), how would lcd code come then?

for example, over here:
ADC_Select_CH4();
HAL_ADC_Start(&hadc1);
HAL_ADC_PollForConversion(&hadc1, 1000);
ADC_VAL_Voltages[0] = readValue5;
readValue5 = HAL_ADC_GetValue(&hadc1);
voltage1
HAL_ADC_Stop(&hadc1);

Thankyou!

Thanks sir it was a great video it helped a lot ;)

can i ask a question sir?....the backlight does not light up. But my lcd setup is in 4bit please i need help, plus my board is installed on a board that uses seperate supply from the data input...really need assisstance

[thetasigma]

It was super helpful, thank you very much sir!

[ProjectAssistant-ycqg]

Great sir..can you make 4 bit LCD and 4x4 keypad interfacing video sir..please

[furkanunal]

Hi Sir,

Firstly, thank you for the video.
It works for me but I want to do this with a temp value that I measure.

[bahriozdem]

very good thank you (teşekkür ederim)

[JYK-uu]

There is an error message for "Project 'LCD' has no explicit encoding set". Can you please let me know how to figure out?

[arifkhan-rbdl]

can you make a video on how to do lcd.h and lcd.c with the help of registers

[saikumarprince]

Hello sir...! My 1st question:-That lcd.h and lcd.c files can use any type board...? Please reply and clarify me...
2nd question:- why you are take random pins like different port pins. Why not take same serial pins like.. PORT-B 0, 1, 2, 3, 4, 5, 6. Can you please clarify my doubts sir

[mbatechmeds]

Thank you Nizar ! Do you take classes also by any chance?

[dishakarnataki]

Hi, Great tutorial..I tried this example for all LCD pins connected to PORTC with connections as below: PORTC0-->RS PORC2--->EN, PORTC3, C4,C5,C6 ----> D4 to D7 but, I am just getting boxes and no display on LCD.. but, if I change my pins to that as shown in example it works fine.. why is it not working for my pinouts that I am using?

[vincegalido]

Hi Sir, thanks for the tutorial. I have a question sir, I can display the value but why it doesn't have backlight sir?

[christiancaballa]

Nice video, can i use this code for nucleo F411RE?

[esathidayet]

thanks man. i like it. if you have mail adress, i want to send a mail about stm32.
