34. How to Calibrate the ADC (Analog to Digital Converter) - STM32 ARM Microcontroller - Part 1

Purchase my new book: Arm Microcontroller Programming and Circuit Building Volume 1

I recommend using the STM32CubeIDE:

How to Set Up the IDE (CoIDE):
How to Connect the ST-Link Programmer:

The STM32 ARM Microcontroller comes with a calibration value for the individual chip at the factory and this can be used to calibrate the ADC so the ADC can output an accurate conversion.

Equipment that I use to make videos:

The way I teach is to understand the fundamentals of production, not Arduino style one-off projects. I urge all Arduino fans that want to develop projects that will be offered to consumers to be production oriented and use the Arduino bare chip to learn how to develop rather than using the Sketch environment and the Arduino boards that contain many passive components that need to be removed during the production development phases.

Great series. As you were doubtless aware, since zero means false, you don't actually have to add != 0 to that if statement.

Great series here, thanks a bunch for the effort!
I'm following along with a STM32F103 and I couldn't set the calibration bit unless the clock source was enable for the ADC and I'm thinking maybe it should have been the first step here also. Doesn't the calibration procedure require the clock source as well?
I've only watched part 1&2 so it might be explained later on, still if someone runs in a similar issue I thought I should mention it.

So what the result of your calibration?

Hi, Can I programm a sensor with ADC? how can i do it with a vibration sensor? Thanks. I really have no idea

Quick question:
Why do we use ADC1? instead of something like ADC2, 3, etc?
Thanks!

[philwolstencroft]

to disable the ADC the spec says to set the ADDIS bit and wait until the ADEN bit is cleared.
Which method correct? Yours or the spec?

Hi Daniel, I love your tutorials to be honest your explanation is very clear, as my English is very poor but still i can understand your explanation very well thanks, now my question is can we do the same thing for PIC micro chip or so.

[rudyarzumanov]

worked perfectly, thanks! btw, your line 8 says "ACD1" instead of "ADC1", fyi.

I have no idea wtf i am doing wrong, i have just created a blank project for a stm32f407vg, i added the stm32f401xc_cmsisboot component thing and i compiled it. I don't know why the component is called 401, i just couldn't find anything else. Maybe it's because i downloaded some weird beta version, but i can't find any other download link on the *AWFUL* coocox website.

the ide also just crashed while i was writing this comment. WTF IS WRONG WITH THIS THING?

edit: i also get an error when i close the project. Fuck this IDE.

Too much speech for so simple operation.
