Hi everyone,

I am trying to configure my nucleo F767 board with cubemx. I tried the LED flashing code using HAL library and it was successful. I used keil v5 to export from cubemx then I added the necessary files to online compiler. Here is the code and file list that I insert from cubemx.

Blinky with HAL

#include "mbed.h"

#include "main.h"
#include "stm32f7xx_hal.h"

void SystemClock_Config(void);
void Error_Handler(void);
static void MX_GPIO_Init(void);
//DigitalOut led1(LED1);


int main()
{
  HAL_Init();
  SystemClock_Config();
  MX_GPIO_Init();
    
    while (1) {
      HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_0);
      HAL_Delay(500);
 
       // led1 = !led1;
       // wait(1);
    }
    
}


void SystemClock_Config(void)
{

  RCC_OscInitTypeDef RCC_OscInitStruct;
  RCC_ClkInitTypeDef RCC_ClkInitStruct;

    /**Configure the main internal regulator output voltage 
    */
  __HAL_RCC_PWR_CLK_ENABLE();

  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3);

    /**Initializes the CPU, AHB and APB busses clocks 
    */
  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
  RCC_OscInitStruct.HSIState = RCC_HSI_ON;
  RCC_OscInitStruct.HSICalibrationValue = 16;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    Error_Handler();
  }

    /**Initializes the CPU, AHB and APB busses clocks 
    */
  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
                              |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSI;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2;
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)
  {
    Error_Handler();
  }

    /**Configure the Systick interrupt time 
    */
  HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq()/1000);

    /**Configure the Systick 
    */
  HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);

  /* SysTick_IRQn interrupt configuration */
  HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);
}

static void MX_GPIO_Init(void)
{

  GPIO_InitTypeDef GPIO_InitStruct;

  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOB_CLK_ENABLE();

  /*Configure GPIO pin : PC13 */
  GPIO_InitStruct.Pin = GPIO_PIN_13;
  GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);

  /*Configure GPIO pin : PB0 */
  GPIO_InitStruct.Pin = GPIO_PIN_0;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
  HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

  /*Configure GPIO pin Output Level */
  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_RESET);

}

void Error_Handler(void)
{
  /* USER CODE BEGIN Error_Handler */
  /* User can add his own implementation to report the HAL error return state */
  while(1) 
  {
  }
  /* USER CODE END Error_Handler */ 
}

here is the list that I added from keil v5 project. /media/uploads/randalthor/cubemx_mbed_dosya_aktar-m-.png

After it was done successfully, I decided to read the encoder and see the value on the computer with Serialpc. The code was compiled without errors but I could not read the values through the serial port. When I deleted the clock settings which is created by cubemx, SerialPC works fine, but the code does not enter the timer because timer value does not change. Here is the code that I used.

Encoder with HAL and mbed

#include "mbed.h"
#include "main.h"
#include "stm32f7xx_hal.h"



TIM_HandleTypeDef htim1;
Serial pc(SERIAL_TX, SERIAL_RX);

static void MX_GPIO_Init(void);
static void MX_TIM1_Init(void);
void SystemClock_Config(void);
uint16_t count=0;



int main() {
    
    HAL_TIM_Encoder_Start(&htim1, TIM_CHANNEL_ALL); 
    
    
    
    HAL_Init();
    SystemClock_Config();
    MX_GPIO_Init();
    MX_TIM1_Init();
    
    
    while(1) {
        
        count=TIM1->CNT;
         HAL_Delay(100);
        pc.printf("Encoder value is %d\r\n", count);
    
    }
}

Where do you think I made a mistake?

Here is the two things that I have learn.

1) Nucleo F767ZI already running at 216Mhz with mbed os. Does not need to speed it up by adding system clock configurations from cubemx.

2) Always pullup your encoders! Now it works.

Could you please tell me what you did to get it to work. Did you delete SystemClock_Config completely or just certain parts of it. I am trying to get some PWM DMA code to work but when I start a HAL_TIM_PWM_Start_DMA my code seems to hang.

Yes, I have deleted SystemClock_Config function. I am using PWM with HAL_TIM_PWM_Start and it works fine. Also, I use ADC DMA with HAL_ADC_Start_DMA function. I do not have any problem with those.

where is this configured in mbed's code? I might need to change it someday, or is there a good reason not to? I'm now having the problem of not getting the functions of stm32l4xx_hal_msp.c replace the weak function of stm32l4xx_hal_adc.c

Do you know if there is an extra step?

Hi all I am using the same board and I kept getting "XXX_HAL symbol multiply defined" error message... Can anyone help?

Thanks!
