90. STM32CubeIDE OLED Display. I2C SSD1306 with STM32F446RE

Do you have any videos on how to implement an external sensor? I'm working on a project that uses an external temperature, but I can't figure out how to obtain the sensor's data.

You're simply the best

"../Core/Inc/ssd1306.h:48:10: fatal error: stm32f4xx_hal.h: No such file or directory " I'm getting error. how can i solve it?

../Core/Inc/ssd1306.h:48:10: fatal error: stm32f4xx_hal.h: No such file or directory I also get this error.

Thank you for this video! I want to do this project! What OLED is that? Where can I get it from?

If you search "ssd1306 oled" in your electronics store, you will find it you can also search in ebay, amazon or aliexpress www.aliexpress.com/item/1005004860363043.html

Hello Sir I want to design a multimeter using stm32f401Re. Thanks to your video, I made the screen of the multimeter using ssd1306. But I could not read the value with the ACS712 current sensor. More precisely, I see the value, but it is not correct. I watched your video about acs712. I wonder if you can design a multimeter using your stm32f4 board?

[@NizarMohideen]

Thanks. ACS712 will measure accurately if the current is more than 1 ampere. It may not be accurate for small currents in mA if the ACS712 sensor is cheaper quality. To get higher current you need low resister load (less than 1 ohm). If you don't have 1 ohm power resistors rated more than 25W, you can use long wires (around 100 metre-500 metre) as load

@@NizarMohideen I didnt know this info .Thank you so much. I measured the current thanks to you .
