I need to make this video project (which uses stm32f407VGT6) in my stm32f469 disco kit in stm32cube ide 1.10.1

I need step by step

Look below for the stm32f469 mcu typing splash screen. There are several options. The chip I normally work on is this: STM32F469NI...

In the quoted video, the author works with pa1 on stm32f407vgt6. What would be the equivalent on the stm32f469 disk kit?:

Did you even look at the schematic for your board? A1 is an Arduino pinout. Your pot is connected to PORTC pin 2.

If you want to connect the pot to PA1, then you need to use pin D3 on the Arduino connector.

Hello @neuberfran​,

You can review the ADC example (using DMA) available under STM32CubeF4 MCU package:

STM32Cube_FW_F4_V1.x.x\Projects\STM32469I-Discovery\Examples\ADC\ADC_RegularConversion_DMA

The example runs on STM32F469xx devices and can be easily tailored to any other supported device.

0693W00000UoD67QAF.png@Imen DAHMEN​ tks. But I need more details answer. Step by step. I open STM32F469I_DISCOVERY in stm32cubeide. (please see photos below). I ran the project. But I can't flash on the board. And I also need to know which pins are being used to connect to the hanmatec dos1102 oscilloscope.

Today I bought a potentiometer (B10K) and I intend to use it in the same project as the video I mentioned above. Will this be possible? Which example project should I use to work with potentiometer?

Hi @neuberfran​ ,

You'll probably want to review this Getting started ow how to use the ADC with DMA, using the STM32L476 with STM32CubeIDE and HAL:

I've evolved a lot but I still haven't been able to. If you look at the video (I repost the link below) at 12 minutes and 53 seconds, it turns the potentiometer and the values change. However, here in my project with the stm32f469 disk kit, nothing changes.

I ask you to look at the photos, please.

In one of them I show my connections on my board.

In another I show the stm32cubeide where I created the ADCDMAExample2 project that still doesn't work fully

I'm using pin a1 and in the video it's pa1. Is this the cause of the problem?
