STM32CubeMX (MCUs)

I'm working with a Stm32 Nucleo F429Zi board and I am having trouble getting the SWV working when debugging. When I created a blank new project and went through the Atollic tutorial to redirect printf() to go to _write() and eventually ITM_SendChar(). This project worked and printed everything fine so I decided to go ahead using CubeMX because I wanted to include lwIP.After creating the project in CubeMX, without altering many settings, I went through the exact same steps as the previous project to redirect printf. However, when I tried printing in a loop the swv console only showed very strange characters (possibly from the extended ASCII codes) but only all at once, not a constant feed from the loop. I tried just using ITM_SendChar and followed it when debugging all the way until it executes, ITM->PORT[0].u8 = (uint8_t) ch; where the ch value was correct. However, when I look at the SWV trace log, the values going into port 0 are random and happen at the same time

STM32F767 project, converted from 4.25.0 to 4.26.1, now it has an error in the ADC1, 2, and 3 configuration where the Scan Conversion Mode is set to Enabled. This value is apparently bogus and I must pick a new value from the drop down list that only contains the value Enabled.Oooohhhh kaaaaay???I guess my testing is done for now.Andrei from The Great White North

Posted on December 22, 2017 at 14:44Dear ST,First is there any publicly available Bug report site?Found with SMT32CubeMX Version 4.23.0and using the latest firmware package for stm32f4 (1.18.0)USB Custom HID Device: STM32CubeMX Parameter Setting: USBD_SUPPORT_USER_STRING is always enable and can not be disabledUSBD_SUPPORT_USER_STRING does not enable the function: uint8_t *     USBD_FS_USRStringDesc (USBD_SpeedTypeDef speed, uint8_t idx , uint16_t *length);  as its preprocessor check, checks on  USB_SUPPORT_USER_STRING_DESCuint8_t *     USBD_FS_USRStringDesc (USBD_SpeedTypeDef speed, uint8_t idx , uint16_t *length); is not added to the USBD_DescriptorsTypeDef when USBD_SUPPORT_USER_STRING is enabled.resulting in a INVSTATE Usagefault when the device is connected to a pc for the first time where the PID / VID combina

Posted on May 24, 2017 at 10:49CubeMX (latest version: 4.21.0) advises NOT to use the 'systick' clock has HAL systick source when FreeRTOS is used (a message box pops up when generating code). So I switched to TIM6.When doing this the generated code seems buggy: in the main() function a call to HAL_Init() initializes the TIM6 and it queries the HAL for the current PCLK clock to do so. However, since SystemClock_Config() is called only later on in main(), the PCLK clock will change and we end up in a wrong systick frequency. In my case it ended up in 50uS instead of 1mS.This happened generating code for stm32l476, and it became very evident when using the IWDT: despite it relies on LSI clock, the SW initialization code relies on HAL systick for register write timeouts. It failed and ended up in an error handler.Using the 'systick' clock as HAL systick seems not affected  (BTW why doing this is discouraged by CubeMX?)#c

Posted on November 20, 2017 at 16:58On our custom board we don't use RTC clock for time or date.But I need to activate RTC to use Backup registers, and we use GPIOC PIN13 in mode OUTPUT_PP for leds.With STM32CUbeMX 4.23.0 and STM32CubeF1 package 1.6.0 I have two options in Pinout :Activate RCT with 'RTC OUT' as 'Disable' or 'No RTC OutPut'.When 'RTC OUT' is 'Disable', in the screen  'RTC Configuration', I can't select 'No output on tamper pin' so GPIOC PIN13 can't be used.When 'RTC OUT' is 'No RTC OutPut', in the generated code we have :hrtc.Init.OutPut = RTC_OUTPUTSOURCE_NONE; which is OK, but the initialisation of time and date uses RTC_BKP_DR1 with value 0x32f2.So I have the choice of not beeing able to use GPIOC PIN13 or RTC_BKP_DR1.I choosed the first Option, and then manually modify the generated code to write hrtc.Init.OutPut = RTC_OUTPUTSOURCE_NONE; Is there another solution ?

See the attached screenshot for the error message that appears.#stm32cubemx #iar

I would like to transfer the data coming to ADC to DMA and average the signals after 15 seconds. I could able to read the values from ADC BUT here are my problems. I am using industrial acceleromoeter while reading adc values i could able to see them when i change the position of accelerometer it does appear in the watch windows of keil but when i connect it to the motor ( to measure the vibrations) I am always getting an error that cannot able to acccess the target !!! so I have decided to store the values read by adc to DMA and calculate the average. I have seen many tutorials but i could not able to find a way to send the data to dma ? how can i achieve that ???? all of the tutorials are using external rc osillator where as i dont prefer to use external oscillator. wont dma work without external osicllator ? hwo can i store the values of adc everytime they change?

Posted on February 06, 2016 at 23:01Hello, while dealing with custom bootloader we have to switch application to certain offset address. Thus we have to move the address of the vector table. While HSE values are supported to be customized vector table offset is not. please add following lines to the system_stm32xxxx.c files: /* &sharpdefine VECT_TAB_SRAM */ ---> &sharpif !defined(VECT_TAB_OFFSET) &sharpdefine VECT_TAB_OFFSET  0x00 /*!< Vector Table base offset field.                                    This value must be a multiple of 0x200. */ ---> &sharpendif Thanks, Regards, Adib. /**********************************************

When I start a new project with a STM32L4R9IDISCOVERY board, the OLED display is not configured and I can't manage to configure it correctly? Why isn't it already configured? Does anyone have a working .ioc file that I can use? None of the example projects include an .ioc​ file

Posted on February 15, 2017 at 04:28It seems STM32CubeMX can not handle well with UTF8 source file.If my main.c is encoded in UTF8, regenerating code in STM32CubeMX will lead to a scrambled mess.

Working with the STM32F429 Discovery board and STMCube_FW_F4_V1.21.0 I've got the same problem several times.If I use the main.c provided with the application examples, the code will run into an endless loop after calling HAL_RCC_OscConfig and taking care of the return value.The program works as expected, if the return value is ignored.The configuration of the PLL causes this behaviour:The check, if the PLL is used as system clock source will go to the else path and returns HAL_ERROR. The calling function expects HAL_OK.

Hi All,​I am using 32L100C Discovery board to develop my own project at the moment and I just need to add watch dog in my code. Everything works fine until I code generate IWDG according to the attached slides although settings are different and RCC is enabled. ​In addition, I have 2 UARTS to transmit and receive packet to third UARTS but it transmitted weird character after code-generate watchdog. I set my ​prescaler to 32 and reload value to 4000 and I did not change anything in the clock configuration. Have I done something wrong and missed something?Kind Regards,William

Hi Everyone,I am using STM32L100RCT6 at the moment for my own personal project and I want to add watchdog function in my code especially IWDG. So I want to ask if there is any tutorial and example code I could use or does anyone has experience in setting it up. Sorry, I am a beginner and this is just the last bit of my own project. Many thanks

Posted on February 22, 2017 at 15:30I'm trying to install STM32CubeMX on Win10 64bit.I know I have Java Version 8 Update 121 installed and I'm sure it's working (since I'm using it).Now when I invoke SetupSTM32CubeMX-4.19.0.exe a window pops open after a couple of seconds saying:STM32CubeMX InstallerThe registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted.And that is it.It doesn't say which Java Version it's looking for nor does it say which one it finds (corrupted).Can somebody help, please??#stm32cubemx #stm32cubemx-install #stm32cubemx-java

Posted on March 30, 2018 at 00:30I was looking at the timing value that STM32CubeMX calculated for the I2C timing register in my STM32F486.  I have the I2C1 clock in at 80MHz.  I checked the data sheet and did not see a maximum value for the I2CCLK and CubeMX is not complaining so I figured it was OK to leave this as is.  When I checked the value for I2C_TIMINGR that CubeMX calculated it seems to be off somewhat.  The value for SCLH is 0x9C and the value for SCLL is EC.  If I back these out to actual time SCLH is 3.925usec and SCLL is 5.925usec.  The I2C clock turns out to be 100502.5Hz, just over the maximum 100KHz it should be.  It seems to me that these values really should be 0x9E and 0xEE.  Am I missing something here?  Thanks.  #stm32f486 #i2c-timing-register #stm32cubemx #i2c-setup

Posted on February 09, 2018 at 21:13I'm using an STM32F779IIT6 configured by the CubeMX (V 4.24.0, STM firmware 1.9).  FreeRTOS is configured for STATIC memory only (important), no dynamic allocations allowed.  I've enabled the USB_HOST_FS system as a Mass Storage Host Class.The generated Cube code under USBH_Init in usbh_core.c snippet is as follows:osMessageQDef(USBH_Queue, 10, uint16_t);phost->os_event = osMessageCreate (osMessageQ(USBH_Queue), NULL);This, in turn, calls osMessageCreate as seen above, which leads to...&sharpelif ( configSUPPORT_STATIC_ALLOCATION == 1 ) return xQueueCreateStatic(queue_def->queue_sz, queue_def->item_sz, queue_def->buffer, queue_def->controlblock);&sharpelseWhile that's all fine and dandy, the queue_def->buffer was NEVER initialized by the Cube code; It's NULL, causing an ASSERT each time the processor starts up.The top lin

I tried to use the STM32CubeMX to configure DAC to work with DMA which would enable me to transfer data from memory, all clocked by TIM6. I used same configuration for STM32F334 and it worked without any problems. After I never got this working, I tried to add another request in DMA configuration menu and discovered this, which looks like some kind of bug, because I haven't found anything like this in reference manual. I believe that STM32CubeMX is not optimized for STM32H7 enough and it looks like this is also the reason why my code wouldn't work with this model.Thank you for reply.

Posted on September 28, 2017 at 11:49In STM32CubeF4 STM32F446ZE, there is a timer one pulse mode example.Setting TIM3 CH2 as input capture and CH1 as Output Compare to work as One pulse mode.(Set slave mode as trigger mode and trigger source as TI2FP2 )It works  totally fine!However, It seems that CubeMX cannot be configured to do this job!(Let's suppose CubeMX is used. I hope this is not a stupid question because I am told to offer an ioc project)Let's review what needs to be done for TIM3 as One Pule Mode using CH2 as Input capture and CH1 as Output compare.1. TIM3 CH2 as input capture2. TIM3 CH1 as Output Compare, PWM mode 23. Slave mode as trigger mode.4. trigger source as TI2FP2.5. one pulse mode is enabled.A typical one pulse mode (OPM) looks like this, Yellow wave is CH2 input capture, Blue wave is the Output compare pulse toggling high w

Posted on August 24, 2017 at 04:41I used STM32CubeMX version 4.22 to generate MSC usb device and modified it to have 2 custom bulk interfaces. I am using STM32F412, FS usb with internal Physical with maximum packet size of 64. Interface 0 has 2 BULK endpoints IN and OUT. Interface 1 have two alternate settings. Alt Setting 0 has 0 endpoints and Alt Setting 1 have 2 BULK endpoints IN and OUT.Endpoints are defined as :&sharpdefine INTERFACE0_IN_EP 0x81&sharpdefine INTERFACE0_OUT_EP 0x01 &sharpdefine INTERFACE1_IN_EP 0x82&sharpdefine INTERFACE1_OUT_EP 0x02My device enumerates fine and Interface 0 works as expected. Host sends Set Interface 1, Alt Setting 1 request then i activate Interface 1 endpoints (0x82 and 0x02).Interface 1 is not working as expected, i am sure it has something to do with my FIFO Settings. I get dataOut Call for INTERFACE1_OUT_EP but when i try to write INTERF

Hey there i want to send and receive LIN Message through my MCU (STM32F091CCT6 - TJA1021T/10/C LIN Transreceiver). But i cant see any example code in documents.Here what i did for this.I select USART1 in LIN mode and USART2 Asynchronous mode to see console messages.Here my clock configurations. My crystal has 12Mhz clock and i want to work at 48Mhz.These are my parameter settings for LIN mode. I select to 19200bps for LIN limitations and i did not use interrupt for this USART.After these settings i generate the code. I add delay for 500ms and send break signals.  HAL_Delay(500);  HAL_LIN_SendBreak(&huart1);When i plugged in oscillator to uart pins i can see a break signal in 500 seconds like that.After that problems start. I cant see any break messages in PLIN API(Peak PLIN USB Converter API to see LIN messages). I can under
