I'm using ADC1 of STM32L452CC. Multi ADCs are connected to 2 Potentiometers and battery level port on ADC1. 2 Potentialmeters are connected to channel 5(PA0) and 6(PA1). (pin10, pin 11) And battery is connected to channel 16(PB1) like below.(pin ...

I'm using STM32L4Q5CGUX on my project. I found some gpio errors. When I write on PB9, it's written on PB8. And I can't write on PB11. Could you guys check together, please?

I installed STM32CUBEMX version 6.1.1 for the project of STM32L5. As I edited Project, I couldn't change Toolchain/IDE to SW4STM32.As below image, I could select only EWARM, MDK-ARM, and STM32CubeIDE.When I make the code through other toolchain...

I'm using ST-LINK of p-nucleo-wb55 board. I tried to connect P-Nucleo-wb55 to the ST-LINK Utility, but I can't. Below the comment of ST-LINK Utility.11:09:19 : ST-LINK SN : 0671FF39373842504306602511:09:19 : ST-LINK Firmware version : V2J35M2611:09:1...

I'm using "STM32L452CC". PA11 pin in connected to battery level checking part. But I can check only ADC1_EXTI11, and I'm using ADC1_IN5,6,7,8,9(PA0,1,2,3,4 pins) DMA_cirgular.So, for battery level checking, I wanna use "GPIO_Analog". But i cannot sea...

I could solve the problem changing two resistors. Next, I should use an opamp. thank you

Can I ask one more thing? I set the code like below. When I set ADC clock to Synchronous clock mode divided by 4, the board not working. But when I get ADC clock to Asynchronous clock mode divided by 4, the board working. I absolutely set clock conf...

YES! That's right. It was stm32l4q5cxxxP. OMG.... I didn't know about that at all.... Thank you for reminding me.

Thank you for your kind comments. I made simple example for this problem. It happened same. I checked other board and I checked hardware pin of STM32L4Q5UX directly by a oscilloscope. Have you ever checked hardware pin of this board or used this boar...

Thank you for your kind comments. However I couldn't resolve this problem. Have you ever checked this port and pin of STM32L4Q5UX_UFQPFN48? I mean port B and pin 8&9. I have updated to CubeIDE version 1.8.0. and CubeMX 6.4.0.202111222105 It also was ...

Measuring battery level by ADC, but level is changing by other adc channel

STM32L4Q5 GPIO hardware fault

Why can't I select the toolchain "SW4STM32" for STM32L5?

Why doesn't P-Nucleo-WB55 connect to the ST-LINK Utility?

How Can I get the battery level using "GPIO_Analog" ?
