STM32CubeMX (MCUs)

Posted on April 11, 2018 at 11:48Hi guys.I'm working in a STM32L433RCTP based project.The code generated by the Stm32CubeMX for clock configuration has no value set for the PLL-M prescaler in the  PLL struct, see original code:---------------------------------- /**Initializes the CPU, AHB and APB busses clocks */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI48|RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.HSI48State = RCC_HSI48_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE; RCC_OscInitStruct.PLL.PLLN = 10; RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV7; RCC_OscInitStruct.PLL.PLLQ = RCC_PLLQ_DIV2; RCC_OscInitStruct.PLL.PLLR = RCC_PLLR_DIV2; if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { _Error_Handler(__FILE_

Posted on September 07, 2017 at 13:48Hello, I'm using STM32F103RBT6 for my project, I've designed a custom board. I'm using cubemx to generate the basic code and Atollic for debugging.I'm reading the switches using external interrupt. In the external interrupt call back, I'm starting a timer. In the timer interrupt handler, I'm doing some work. I've kept the timer timeout period to 2 seconds. My problem is whenever the code is started to run for the first time and when I press the switch, the code immediately  goes to the timer interrupt handler. This happens only once for the first time. After this, whenever I press the switch, code goes to the timer interrupt in 2 seconds which is correct. Why does it go immediately goes to the interrupt handler for the first time and then works fine thereafter??I've attached the c file for reference. Is there any cha

Posted on February 05, 2018 at 15:41Hello,I noticed a problem while trying to generate code with CubeMX, regarding injected ADC.The problem appears as follow:- Make a project with Cube on a Nucleo-F413ZH,- Use default pin attribution,- set PC0, 1, 2 to analog,- configure 3 Conversions in ADC_Injected_ConversionMode,- rank 1 -> channel 10, rank 2 -> channel 11, rank 3 -> channel 12,- use Low Layer for ADC,- generate code.    /**Configure Injected Channel     */  ADC_INJ_InitStruct.TriggerSource = LL_ADC_INJ_TRIG_SOFTWARE;  ADC_INJ_InitStruct.SequencerLength = LL_ADC_INJ_SEQ_SCAN_ENABLE_3RANKS;  ADC_INJ_InitStruct.SequencerDiscont = LL_ADC_INJ_SEQ_DISCONT_DISABLE;  ADC_INJ_InitStruct.TrigAuto = LL_ADC_INJ_TRIG_INDEPENDENT;  LL_ADC_INJ_Init(ADC1, &ADC_INJ_InitStruct);

Posted on April 02, 2018 at 17:41Hello ST,I found that code, generated by STM32CubeMX for STM32F4 SDIO periperal, is poorly integrated with MCI interface (CMSIS driver). And doesn't work out of box without modification.STM32CubeMX generates HAL_MMC_MspInit function (file stm32f4xx_hal_msp.c). But MCI interface expect HAL_SD_MspInit (file MCI_STM32F4xx.c, line 543).Another problem related to SDIO_IRQ. I've disabled SDIO global interrupt here, because MCI_STM32F4xx.c has SDIO_IRQHandler already:(otherwise STM32CubeMX generates second SDIO_IRQHandler)But in this cas

I would like communicate with DS3231 RTC chip.I wroted small easy code :void DS3231_DateTime_get(void){ DS3231.ds3231_TX_buff[0] = 0x00; HAL_I2C_Master_Transmit(&hi2c1, DS3231_address << 1, &DS3231.ds3231_TX_buff[0], 1, 1000); HAL_I2C_Master_Receive(&hi2c1, DS3231_address << 1, &DS3231.ds3231_RX_buff[0], 7, 1000);//HAL_I2C_Mem_Read(&hi2c1, DS3231_address << 1, 0x00, I2C_MEMADD_SIZE_8BIT, DS3231.ds3231_RX_buff, 7, 1000); DS3231.second = BCD2DEC(DS3231.ds3231_RX_buff[0]); DS3231.minute = BCD2DEC(DS3231.ds3231_RX_buff[1]); DS3231.hour = BCD2DEC(DS3231.ds3231_RX_buff[2]); DS3231.day = BCD2DEC(DS3231.ds3231_RX_buff[3]); DS3231.date = BCD2DEC(DS3231.ds3231_RX_buff[4]); DS3231.month = BCD2DEC(DS3231.ds3231_RX_buff[5]); DS3231

Posted on March 26, 2018 at 14:29Hey, i tried to setup my STM32L4R9 with CubeMX v4.25.0 as followed:- FreeRTOS- FatFS- SD Card- DMA Support unfortunately i noticed that the DMA-Interrupt tab does not show up in the SD-Card settings. I tried it with other STM32 MCUs where it showed up instantly. Is there anything i can do/configure to activate the DMA-Interrupt feature for the L4R9 in CubeMX? I saw there is an demo project with my requirements for the L4R9 on the eval board.. but would love to have it in CubeMX too! Regards#cubemx-v4.25.0 #stm32l4+ #fatfs #dma-sdmmc

Posted on April 22, 2018 at 05:41HELLO..I want to measure the frequency and duty cycle of the external signal. I have gone through some example available , and suggestions on website. Everywhere they are using either channel 1 or channel 2 in any of timer , unfortunately in my case signal is given to channel 4 ,  Is it still possible to measure duty cycle and frequency by using channel 4 , if so how to configure the same in stm cubemx ..Can anybody suggest please , I am fully stuck with this issue ..Thank you#pwm-input #stm32h7 #cubemx

Posted on April 13, 2018 at 11:06hey,I have a LWIP client/server application and I want to add the PTP synchronization feature to the communication. I'm using STM32F746ZGTx Nucleo and CubeMX. I'm trying to enable RMII_PTP_Synchro mode for ETH (after enabling TIM2) but cubeMX is displaying the following message:'Warning: STM32CubeMX does not support the configuration of this IP's mode. You can configure it only manually'.I can't start this configuration from scratches so is there any precoded sources I can relay on to activate and configure this feature?Thanks.#ptp #stm32f7 #cubemx #ieee1588

Posted on April 12, 2018 at 19:25CubeMX is a great tool but there is something I am not understanding. I am using System Workbench to write my project. If I go back to CubeMX to make a change it tend to wipe out the code I've added to main.c.  Should I put all my code in a separate source file and leave main.c as unchanged as possible? What is the right way to do this?#system-workbench #cubemx #workflow

Posted on September 01, 2015 at 19:13Hi to every one,It's the first time that I use the STM32CubeMX + SWSTM32 to program a stm32f401RE board. I have done already some example project but I can't use the printf() function to communicate  with a terminal ( Tera Term) on the PC. Somebody can explain me how I can do it?Thank you in advance!!

Posted on April 12, 2018 at 21:08I want to use I2S for single MP45DT02 MEMS microphone, for which I2S WS pin is not needed. CubeMX forces WS pin when enabling I2S peripherial, but I need to use this pin as GPIO for something else. Is this a bug in CubeMX and can I reassign this pin as GPIO in project, or is it not possible and it has to be WS pin even when it is not used?#cubemx-v4.25.0 #stm32-f7

Posted on February 04, 2017 at 19:00Hi,I used to use cubemx with 1.5.1 firmware. I am using NUCLEO-F767ZI board. After formatting my computer, I realize that there is something new in timer configuration lines. It comes as:htim(anyofthem).Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;After cubemx, I am adding configuration files to the mbed OS and it returns error for that lines.If I just delete that line, is the board works properly?#cube-mx #nucleo-f767zi

Posted on March 15, 2017 at 09:59 I discovered CubeMX 4.20 always generates code where VBUS sensing is enabled, no matter if it is ticked in CubeMX or not. This caused enumeration fails in several projects where PA9 is not used by me (I use it in CDC Virtual Com Port mode) Affected code file is usbd_conf.c line 299 (line 18 in snippet) USBD_StatusTypeDef USBD_LL_Init (USBD_HandleTypeDef *pdev) { /* Init USB_IP */ if (pdev->id == DEVICE_FS) { /* Link The driver to the stack */ hpcd_USB_OTG_FS.pData = pdev; pdev->pData = &hpcd_USB_OTG_FS; hpcd_USB_OTG_FS.Instance = USB_OTG_FS; hpcd_USB_OTG_FS.Init.dev_endpoints = 4; hpcd_USB_OTG_FS.Init.speed = PCD_SPEED_FULL; hpcd_USB_OTG_FS.Init.dma_enable = DISABLE; hpcd_USB_OTG_FS.Init.ep0_mps = DEP0CTL_MPS_64; hpcd_USB_OTG_FS.Init.phy_itface = PCD_PHY_EMBEDDED; hpcd_USB_OTG_FS.Init.Sof_enable = DISABLE; hpcd_USB_OTG_FS.Init.low_power_enable = DISABLE; hpcd_USB_OTG_FS.Init.lpm_enab

Posted on April 12, 2018 at 11:26Hi guys.I'm working on a STM32L433RCTP based project with STM32CubeMX.It's probably not the best idea to use CubeMX as a reference, if you have the datasheet / ref manual....It took some hours for me to figure out, why there are some pins not responding to what I've done with them. Here is the reason: I located the pins by looking at the CubeMX drawing. But in STM32CubeMX there are some pins wrong.I took two screenshots. On the right side, there is a screenshot from the datasheet and on the left side you can see a screenshot from CubeMX. The CubeMX screenshot is overlayed by the pin names, extracted from the datasheet screener. So you can compare the pins in CubeMX with the pins in the datasheet.As you can see, the pins in the red boxes doesn't match with the ones from the datasheet.

Posted on January 24, 2018 at 19:28Hello,There were questions similar to this before, but not exactly. This is applicable to STM32CubeMX V4.24.0 with STM32CubeL4 fw package V1.11.0 (latest at this time).Previously code generated by STM32CubeMX for configuration of SDMMC+FATFS+DMA+RTOS was not working. Some workarounds were found on the discussion boards which required modification of code generated by STM32CubeMX (i.e. these modifications would be erased by following code regenerations). The code generated by STM32CubeMX did not match code from the STM32CubeL4 package (STM32Cube_FW_L4_V1.11.0\Projects\32L496GDISCOVERY\Applications\FatFs\FatFs_uSD_DMA_RTOS). For example, SD_initialize() function from sd_diskio.c was missing initialization of queue SDQueueID (compared to the same function in sd_diskio_dma_rtos.c from the STM32CubeL4 example). Essentially, the queue was left uninitialized at all

Posted on February 13, 2018 at 23:38Hi There,I've just switched to using Atollic (from System Workbench) and am having issues with the code generation in STM32CubeMX.  When I build a project using 'generate under root', the code will not compile with undefined references to all the HAL functions.e.g. errors like..\STM32_workspace_9.0\TEST_PROJECT_UNDERROOT\Debug/..\Src/hrtim.c:69: undefined reference to `HAL_HRTIM_Init'If I generate with this box unticked then there are no problems.I am using: STM32CubeMX V4.24STM32Cube FW_F3 V1.9.0Atollic TrueStudio V9.0.0#atollic-truestudio #stm32cubemx

Posted on June 25, 2017 at 23:49I am using STM32CubeMX 4.21.0 for STM32L4.  When using FreeRTOS with tickless support, the freertos.c file is generated with functions decleared __weak, but this macro is not defined.  I am generating for GCC.  I am running on Linux.__weak void PostSleepProcessing(uint32_t *ulExpectedIdleTime){/* place for user code */}I am getting annoyed at having to add/* USER CODE BEGIN Includes */ &sharpdefine __weak __attribute__((weak))/* USER CODE END Includes */Can you reproduce the problem?#freertos #stm32cubemx #linux #gcc

Posted on March 11, 2017 at 19:02Sometimes, STM32CubeMX just stuck at generating code, and i am not able to do anything. Just end the process from Task Manager. What does happen?P.S. Jawaw.exe in the Task Manager not load my CPU at all.#stm32cubemx

Posted on April 06, 2018 at 21:47Now that encoder mode seems to be missing from CubeMX, at least for STM32F070 and STM32F407 devices, what is the most 'CubeMX-friendly' way to use it? The idea is to generate a CubeMX project, then run a script to make it a project for the IDE we're using. Both devices have encoder mode capable timers.And why is it, that I've seen F7xx devices configured to use encoder mode with CubeMX? Is the CubeMX itself different or what's the thing?#cube-mx #encoder-mode #quadrature-encoder

Posted on March 26, 2018 at 17:00Hey guys,i am right now working on the Nucleo L476 RG Board. I generated source code with STM32CubeMX (v4.25). I am using the internal opamp in 'Follower' mode and reading the output with the on-board adc. VCC is 3.3 V.When applying different voltage levels to the input of the internal opamp i have seen that the opamp output never goes below 1.4 V even when i directly short the input to GND. Above 1.4 V everything works like expected.Does anyone have a clue what is going wrong/missing in the code to make it work over the full spectrum?Thank you and best regards,Alex
