ADC_Enable is timing out on STM32G031G8

I'm getting a timeout error when trying to configure a G031 to convert 8 channels. Any ideas what could be causing this? Here is the code: /* USER CODE BEGIN Header */ /** ***************************************************************************...

Pull resistor in I2C in STM32f334

I am using STM32f334 I2C as master and my slave is Arduino UNOMy problem is I am unable to receive anything from my masterI think the problem here is pull resistor, first I tried using Internal pull resistor but it did not work, then I tried with 2k ...

How to separate variables using MPU on STM32F429ZI?

This is kind of a broad question, but I'm having a bit of trouble understanding/finding resources on using the MPU on this MCU. My goal is to partition some of the variables in my code so that they cannot be accessed by accidental writes/overflow, an...

Debugging from bank 2

I'm working with Nucleo-f439zi board.I use dual banking feature.I cannot find a way to debug from bank 2how to debug application from bank 2 ?

Is internal pull up the same as external pull up resistor.

for example IC2 needs pull up resistor on the board but there is internal pull up options for pins.I wonder if this is the same. So by setting internal pull up you can skip the pull up resistors on the board. I know that NRST pin has internal pull up...

Unexpected behaviour of output PWM signals during flashing phase.

Hi, I'm using STMH755BIT MCU.I've configured three TIM1 channels to generate PWM signals, everything is working correcty except during the initial phase of software download, when PWM signals self-enable for approximatly 150ms, and then return correc...

Which flag definition would be faster ?

I have a lot of different flags in project, I wonder which style definition reads faster by processor .Definition 1     typedef struct{   __IO uint8_t flag1 ;   . //other flags     }Flag_t ;     Definition 2     typedef struct{   ...

How to search appropriate STM32

I'm looking for an STM32 which features:-Cortex M4 or M7-CAN bus capability -FPU/DSP capability-at least 512kb flash (tough I prefer 1MB or even more)-no BGA (I need to adapt it manually to a breadboard for testing - BGA makes things complicated at t...

What options/methods are there for the STM32F103CBT6 if we want to upload new software and check if it is ok, before we run it? I see options like dual NVM bank. But dont think it applies to the 32F103. regards, rob
