This was a great tut, thank you. It would be nice to see more esp-idf material coming from your level of engineering. As you've probably noticed most are dumping ST Microelectronics and aren't participating in their pricing and hoarding scams anymore. Espressif and GigaDevice seems to be the "Go To" alternatives

it doesn't work for me my lcd displays random things and i used chatgpt to understand why but till now i didn't find a solution to that problem. I modified the delays and i used the address 0x27 in my code according to my i2c but nothing works 😢😢 HELP SOS

Great teacher!! Thank you! Do you have an example with 2 components? For example: using uart and display.

Thanks a lot for this article. I am trying hard to make this lcd screen work on my esp32, but for some reason I can't. Maybe it's because of some config related to the espressif idf, like clock speed? When I use Arduino IDE with the same hardware, It works, but with the IDF. Does not. I tested my codes using the wokwi and I'ts working too. Probably it's something related to my environment.

We need to see your face. Tell us about yourself. Your video is very good. Please make video about yourself.

I had to increase my delays in the lcd_init function to get it to work. Before that random garbage was displayed on the lcd so maybe can help others.

Excellent tutorial video. I will be following this series, thanks.
Why did you not have to #include "esp_log.h" in i2c-lcd.c I got an error when I didn't. I will have to put a logic analyzer on the display I am getting garbage, even though the code is the same except I use vtaskdelay instead of the usleep() functions which should not make any difference.

Do you know what I would need to change to the code inorder to use it for NHD CIZ model

What is the text to speech software you used... I heard it on multiple youtube videos. It's iconic.

Hi,
Where did you find i2c-lcd library?

[qzorn]

high great info. i am trying to play with the: LILYGO I2C TTGO T-CAN485 ESP32 CAN RS-485 Supports TF Card WIFI Bluetooth Wireless... do you know how to find the I2C SDA SCL pins to use with any of the SSD1306 oled 3.3v displays? thank you.

Hi, Very nice video but I see the using flash over 133K bytes!! is this really true? for a small simple program like this?

i am using 128*160 rgb tft_lcd display but i get error after flash like end of the video what you shown please can you solve my queory

Can anyone help me to find out I2C SCL AND SDA pin 'ESP32C3 mini 1' ?

[MetallKnighT]

can you do a video about TFTP client, STM will acte as client --> request a flash file from tftp server and do a firmware or software update

[tungvu]

can i change the default pin for i2c connection of ESP32

[shoyur]

whatever im doing, this doesnt work on the ESP32-S3-WROOM-1 :(
anyone else ?
