Target: STM32L031C6T6editor: SMT32CubeIDE using HALI getting crazy soon. I cannot get this ADC to read correct. I think I missing something important. I googled and googled again and again.I have two voltage on two separate channels (7 & 8). 6.9V and...

I use ADC 12 bit in STM32L03 and cannot find where CubeIDE defines which reference voltage the ADC should have. ADC_Init() is auto-generated. Is it the default used and what voltage is it?The processor is fed with 3.3V and has VDDA connected to that ...

Does anyone have any tips on creating quick bookmarks in the left margin? On other editors I can use Ctrl+F2 to set several bookmarks within same file. Then use F2 within that particular source code file to find the nearest/next. Missing it in STM32C...

I using STM32CubeIDE and STM32L03.I don't understand how to make a simple sample of a ADC channel (in blocking mode). I had config the Cube to generate a ADC_Init() that contains my 6 Analog In channels. I want to have a function that goes like this...

The Atmega project that I trying to get into a STM32 uses two UART ports and each have its own sets of IRQ vectors. That is RX- and UDRE irq. The last one gives an IRQ when the TX-register is empty.As I said in the latter post, I haven't worked with ...

I made the ADC_Read without HAL. Now it is working. I cannot spend more time on this. Must move on.

Thanx for answer. I have eariler used higher sampl.time just for test and it did not help. Same now. Did not help. (I haven't read Table 58. Thanx for letting me know.)I do not need to use any setup regarding Vref+ or something? I just accept CubeIDE...

What you are saying is that I use the internal reference to find out the ADC "quality" and then I measure the external ref 3.3V (which is not always exactly 3.30V) and apply the calibration factor from before to the external reference and to future m...

@AScha.3 . Thanx. I suspected this. You wrote "because Cube cannot set, what voltage you supply to the pin (which is vref+)"I thought some register needed to be set that tells the AD that "your ref is at pin VDDA, not the internal vref".

It seems to be 3.3V but I don't like not finding the precise code that sets it to 3.3V.

Wrong ADC values. Why?

Where is ADCREF voltage set?

Any Ctrl+F2 marker/bookmark in CubeIDE?

I want to sample one (of six) ADC channel for 2 ms in blocking mode. How hard can it be?

Dealing with interrupts. Diff Atmega - STM32.
