Hello sir, this video was uploaded 3 years ago from the moment this comment comes down so I don't know if I can convey this to you. I have spent so long trying to get my tzt0.42 to work with my stm32f401RCT6 blackpill and this was the video that finally got it to work. Thank you so very much!

Thumbs up for adding the source code to video description!

Hi, thanks for the videos you are sharing. Kindly create a tutorial how to use the internal temperature sensors in the STM32 chips

[mertoguzhan]

thank you man, very helpful content !

[manofmesopotamia]

thank you so much, you teach me a lot of things, I really appreciate your efforts.😊

[remontlive]

You are made a great and easy tutorial? thank you indeed!

[galalahmedfahmy]

Hello Nizar. What display do you use in this video ? I see it's SSD1306 based display, but which model do you use exactly ? It's colors display. Thanks you very much for nice demonstrations!

itoa function was not available. Got an error because of the function missing. Please let me know how to resolve this issue.

uint8_t sicaklik;
char dizi[5];

while(){
sprintf(array, "%d", temp);
SSD1306_GotoXY (53, 30);
SSD1306_Puts (array, &Font_11x18, 0);
SSD1306_UpdateScreen();
HAL_Delay (500);

}

I checked in the debugging environment, there is no issue with the conversions. When going from two-digit temperatures to three-digit ones, there is no problem. However, when the temperature drops below 100 degrees, instead of getting 99, 98, 97, I'm getting 990, 980, 970. What could be the reason for this?

While uploading the code each time, I'm getting an error :
Error in final launch sequence:

Failed to execute MI command:
target extended-remote localhost:3333

Error message from debugger back end:
localhost:3333: Connection timed out.
Failed to execute MI command:
target extended-remote localhost:3333

Error message from debugger back end:

localhost:3333: Connection timed out.

Just after I use the run option or debugger run. Why so?

I did everything perfectly but the display still does not turrn on, what should i do ??

[lucadebs]

Did you write the .c and .h files we created in Src and Inc? If you didn't, do you know where I can find a tutorial explaining how they were created? Thank you.

[farukdemirta]

I just did what you did but it didn't work I don't understand the problem connection and code is right but screen is nothing show up.

[miker]

Excellent video and a huge thank you! Any idea if it's possible to rotate the screen 180 degrees? It looks ike it might be in SSD1306_Init somewhere.

Hi. I am trying to add more fonts. But I did'nt find any program to output 32bit format font archive. Only 8 bit format! Could you tell me wich program did you use? Thanks a lot.

i tried your code on stm32f030c8t6 it worked that time, now i am trying the same with stm32f103c8t6 but it is not working with and its new version display, though i studied its datasheet the address it says is 0x3C, i tried every address, its not working at all, even made pull up connection, the sda and sck lines both remains in high state, suggest me to fix it

[sarankumar]

can you plese give me the code for spi display with 7pins for stm32f103c8t6 (or please tell me the inilization process of spi communication in stm32cubeide

[shihab]

sir, what about the color of text? can i print multiple color text in this display or it has these color by default?

[thaitoantran]

I had a problem with "itoa". Can you help me?
